Description
The invention relates to improved compositions comprising a
water-soluble and/or water-insoluble active material having the
capacity to impart a residual characteristic to surfaces treated
therewith such as antibacterial compounds, tarnish inhibitors,
ultra-violet absorbers, fluorescent brighteners, bluing agents and
skin treating materials and an aminopolyureylene (APU) resin in an
amount effective to enhance the effects of the active materials.
The APU resins appear to enhance the deposition and/or retention of
the water-soluble and waterinsoluble active substances on the
surfaces contacted therewith.
The capacity of the APU resin to improve the effectiveness of the
active materials on surfaces contacted therewith surprisingly is
maintained in the presence of water-soluble organic detergents and,
therefore, detergent compositions containing the mixture of active
material and APU resin represent preferred embodiments. Such
detergent compositions include dishwashing detergents, shampoos,
laundry detergents, hardsurface cleaners and toilet bars. The
effectiveness of the APU resins in the presence of minor and major
amounts of watersoluble organic detergents is surprising because
the effectiveness of the active materials is due to the deposition
and/or retention of the active materials on surfaces contacted
therewith and detergents normally tend to minimize deposition and
retention of such materials on the washed surfaces. Thus, usually
only a small percentage of the active materials in a detergent
composition is actually retained on a particular surface or
substrate after washing and, optionally, rinsing. Accordingly, to
achieve a particular level of activity, the concentrations of
active material must be increased-with an attendant increase in
cost - when used as a component in a detergent composition.
While the mechanism by which the improved effects are obtained is
not understood, it appears that the APU resin may unite either with
the active material or the contacted surface to increase the
affinity of the active material for the surface. In many cases, an
increase in the weight of active material retained by the surface
has been quantitatively verified. However, no absolute mechanism
has been defined and the invention is not limited to any particular
theory.
Generally, the improved compositions of this invention consist
essentially of a mixture of an aminopolyureylene resin having a
molecular weight in the range of about 300 to 100,000 and a
water-soluble or water-insoluble active material having the
capacity to impart a residual property to surfaces treated
therewith and selected from the group consisting of (A)
antibacterial compounds, (B) tarnish inhibitors, (C) ultra-violet
absorbers, (D) optical brighteners, (E) bluing agents and (F)
skin-treating compounds, the weight ratio of resin to active
material being effective to improve the effects of the active
material and selected from the range of 1:1 to 20:1 preferably 1:1
to 5:1. Preferred compositions are detergent compositions
comprising 2% to 99% by weight of a water-soluble, organic
detergent, 0.05% to 5% by weight of aminopolyureylene resin and
about 0.05 to 5% by weight of active material.
Also, within the scope of the invention is a method for improving
the effectiveness of active materials on surfaces contacted
therewith which comprises contacting the surface with a water
solution or dispersion of the active material and an effective
amount of the aminopolyureylene resin sufficient to improve the
effect of the active material retained on the treated surface after
the contacting solution is removed.
The APU resins suitable for use in the described compositions and
method have a molecular weight in the range of about 300 to 100,000
and are characterized by the following repeating unit:
--(CH.sub.2).sub.n X--(CH.sub.2).sub.n NHC(Y)NH--
wherein X is NH, N--C.sub.1 to C.sub.22 alkyl, ##SPC1##
Y is O or S, and n is 2 or 3. Such APU resins and their cosmetic
effectiveness are set forth in the copending application of Paul
Grand entitled "Cosmetic Compositions" filed of even date
herewith.
Thus, suitable APU resins include both the polyurea and the
polythiourea-containing compounds. Preferred APU resins have a
repeating unit where Y is oxygen, n is 3, and X is selected from
the group consisting of N--C.sub.1-8 alkyl and ##SPC2##
Generally, the number of repeating units in the resin will be
sufficient to yield a polymer having a molecular weight in the
range of about 300 to 100,000. Preferred APU resins have an average
molecular weight in the range of 1,000 to 20,000 and a particularly
preferred resin is the reaction product of equimolar quantities of
N-methyl, bis(3-amino-propyl) amine and urea having a molecular
weight of about 4,300.
The molecular weight of the APU resins is based upon aqueous gel
permeation chromatographic analysis. The separation is carried out
in oxalic acid solution, adjusted to pH 3.5, on three Corning
controlled-pore glass columns (nominal pore sizes 175,125 and 75A)
in series. Detection is by differential refractometer. Reference
compounds are dextran polysaccharides of molecular weights of
150,000, 110,000, 40,000, 20,000 and 10,000 and sucrose and
galactose.
The APU resins which can be used in the compositions of this
invention are prepared by reacting, for example, 145 grams of
N-methyl bis (3-aminopropyl) amine (1.0 mole) and 60 grams of urea
(1.0 mole) in a 3-necked flask equipped with a therometer,
mechanical stirrer, condenser, and nitrogen sparge tube. Nitrogen
is bubbled slowly through the solution throughout the course of the
reaction. The solution is heated to 140.degree.C. over a 20-minute
interval where ammonia begins to evolve. The solution is further
heated to 250.degree.C. over a 30-minute interval and allowed to
cool. The product is a hard, resinous powder (Resin A) having a
molecular weight of about 4,300. The secondary amine analogues can
be made by the above process if bis (3-aminopropyl) amine or bis
(2-aminoethyl) amine are reacted with urea or thiourea. The
piperazine analogues are made by reacting N,N'-di(3-aminopropyl)
piperazine or N,N-di (2-aminoethyl) piperazine with urea or
thiourea. The N-C.sub.1 to C.sub.22 alkyl analogues are prepared by
reacting N-C.sub.1 to C.sub.22 alkyl bis(3-aminopropyl) amine or
N-C.sub.1 to C.sub.22 alkyl bis(2-aminoethyl) amine with urea or
thiourea. Additional analogues are prepared by the following
reactions: ##SPC3##
The preparation of the remaining analogues is well within the skill
of the art following the above techniques.
The active materials which are potentiated by the APU resin are
well known and have been used for treating surfaces and substrates
to impart certain residual characteristics to the contacted
surfaces. The treated surfaces or substrates include proteinaceous
materials such as hair and skin, textiles such as cotton, rayon and
synthetic fibers, and porcelain, wood, plastic and metal. Such
active materials may be water-soluble such as cetyl dimethyl benzyl
ammonium bromide and gelatin or water-insoluble such as zinc
2-pyridinethiol-1-oxide and optical brighteners. To facilitate
activity and utility, the water-insoluble materials are usually in
the form of finely divided particles having a diameter in the range
of about 0.5 to 50 microns. Suitable active materials include
antibacterial compounds, tarnish inhibitors, ultra-violet
absorbers, optical brighteners, bluing agents and skin treating
materials such as hydrolyzed proteins, silicones and
polyacrylamides.
Antibacterial compounds which may be used in the compositions
include water-soluble and water-insoluble salts of
2-pyridinethiol-1-oxide, substituted salicylanilides, substituted
carbanilides, halogenated bisphenols, mono-higher alkyl quarternary
ammonium salts, and 5,7diiodo-8-hydroxyquinoline.

A bluing material which is potentiated by APU resin is ultramarine
blue. This is a well-known blue pigment occurring naturally as
mineral the lapis lazuli. It can be made, for example, by igniting
a mixture of kaolin, sodium carbonate or sulfate, sulfur, and
carbon. It is insoluble in water and is stable when in contact with
bleaching agents, alkali, and light. Details for synthetic
ultramarines are given in the text "Ultramarines, Their History and
Characteristics," Reckitts (Colours) Ltd., Hull, England. Preferred
are micropulverized, synthetic ultramarine blues, particularly
grades RS4-RS8 provided by Reckitts. The pigment is in the form of
particles substantially all of which exhibit a diameter of less
than about 0.05 millimeter, and is characterized by the ability to
impart a faint blue visible shade to fabrics treated therewith
without staining such fabrics when used at recommended
concentration and fashion, being generally considered to be
non-substantive, or at least non-accumulative, on fabrics.
The skin-treating materials which are enhanced by the APU resins
are the water-soluble, substantive proteins. Such proteins are
substantive to the hair and skin in the presence of detergents.
Suitable proteins are water-soluble polypeptides, having a
molecular weight in the range of about 120 (amino acid) to about
20,000, preferably from about 800 to 12,000. Such polypeptides are
obtained by hydrolysis of protein materials such as hides, gelatin,
collagen, and the like, with collagen protein being preferred,
using well-known processes. During hydrolysis the protein materials
are gradually broken down into their constituent polypeptides and
amino acids by prolonged heating with acids, e.g., sulfuric acid,
or alkalis, e.g., sodium hydroxide, or treatment with enzymes,
e.g., peptidases. First, high molecular weight polypeptides are
formed, and as hydrolysis proceeds these are converted
progressively to simpler and simpler polypeptides, to tripeptides,
dipeptides, and finally to amino acids. It is obvious that the
polypeptides derived from proteins are complex mixtures. The
preferred hydrolysates are obtained from bone- or skin-derived
collagen protein by enzymatic hydrolysis and are sold under the
trade names "WSP-X-250" and "WSP-X-1000" of Wilson Pharmaceutical
and Chemical Corporation.
Other skin-treating materials whose skin-slip or anti-friction
properties are enhanced by APU resins include ethylene oxide
polymers having a molecular weight in the range of about 500,000 to
1,000,000 which are sold under the trade name "Polyox."
The water-soluble organic detergent materials which can be used in
forming the preferred detergent compositions of this invention may
be selected from the group consisting of anionic, nonionic,
amphoteric, zwitterionic, polar nonionic, and cationic detergents,
and mixtures of two or more of the foregoing detergents.
The anionic surface-active agents include those surfaceactive or
detergent compounds which contain an organic hydrophobic group
containing generally 8 to 26 carbon atoms and preferably 10 to 18
carbon atoms in their molecular structure, and at least one
water-solubilizing group selected from the group of sulfonate,
sulfate, carboxylate, phosphonate and phosphate so as to form a
water-soluble detergent.
Examples of suitable anionic detergents which fall within the scope
of the anionic detergent class include the water-soluble salts, for
example, the sodium, ammonium, and alkylolammonium salts, of higher
fatty acids or resin salts containing about 8 to 20 carbon atoms,
preferably 10 to 18 carbon atoms. Suitable fatty acids can be
obtained from oils and waxes of animal or vegetable origin, for
example, tallow, grease, coconut oil, tall oil and mixtures
thereof. Particularly useful are the sodium and potassium salts of
the fatty acid mixtures derived from coconut oil and tallow, for
example, sodium coconut soap and potassium tallow soap.
The anionic class of detergents also include the water-soluble
sulfated and sulfonated synthetic detergents having an alkyl
radical of 8 to 26, and preferably about 12 to 22 carbon atoms.
(The term alkyl includes the alkyl portion of the higher acyl
radicals.)
Examples of the sulfonated anionic detergents are the higher alkyl
mononuclear aromatic sulfonates such as the higher akyl benzene
sulfonates containing from 10 to 16 carbon atoms in the higher
alkyl group in a straight or branched chain, for example, the
sodium, potassium, and ammonium salts of higher alkyl benzene
sulfonates, higher alkyl toluene sulfonates, higher alkyl phenol
sulfonates and higher naphthalene sulfonates. A preferred sulfonate
is linear alkyl benzene sulfonate having a high content of 3- (or
higher) phenyl isomers and a correspondingly low content (well
below 50 percent) of 2- (or lower) phenyl isomers, that is, wherein
the benzene ring is preferably attached in large part at the 3 or
higher (for example, 4, 5, 6 or 7) position of the alkyl group and
the content of the isomers in which the benzene ring is attached in
the 2 or 1 position is correspondingly low. Particularly preferred
materials are set forth in U.S. Pat. No. 3,320,174.
Other suitable anionic detergents are the olefin sulfonates,
including long-chain alkene sulfonates, long-chain hydroxyalkane
sulfonates or mixtures of alkene sulfonates and hydroxylalkane
sulfonates. These olefin sulfonate detergents may be prepared in a
known manner by the reaction of SO.sub.3 with long-chain olefins
containing 8 to 25, preferably 12 to 21 carbon atoms and having the
formula RCH=CHR.sub.1 where R is a higher alkyl group of 6 to 23
carbons and R.sub.1 is an alkyl group of 1 to 17 carbons or
hydrogen to form a mixture of sultones and alkene sulfonic acids
which is then treated to convert the sultones to sulfonates. Other
examples of sulfate or sulfonate detergents are paraffin sulfonates
containing about 10 to 20 and preferably about 15 to 20 carbon
atoms, for example, the primary paraffin sulfonates are made by
reacting long-chain alpha olefins and bisulfites and paraffin
sulfonates having the sulfonated group distributed along the
paraffin chain as shown in U.S. Pat. Nos. 2,503,280; 2,507,088;
3,260,741; 3,372,188; and German Patent 735,096; sodium and
potassium sulfates of higher alcohols containing 8 to 18 carbon
atoms such as sodium lauryl sulfate and sodium tallow alcohol
sulfate; sodium and potassium salts of .alpha.-sulfofatty acid
esters containing about 10 to 20 carbon atoms in the acyl group,
for example, methyl .alpha.-sulfomyristate and methyl
.alpha.-sulfotallowate, ammonium sulfates of mono- or di-glycerides
of higher (C.sub.10 - C.sub.18) fatty acids, for example, stearic
monoglyceride monosulfate; sodium and alkylolammonium salts of
alkyl polyethenoxy ether sulfates produced by condensing 1 to 5
moles of ethylene oxide with one mole of higher (C.sub.8 -C.sub.18)
alcohol; sodium higher alkyl (C.sub.10 - C.sub.18) glyceryl ether
sulfonates; and sodium or potassium alkyl phenol polyethenoxy ether
sulfates with about 1 to 6 oxyethylene groups per molecule and in
which the alkyl radicals contain about 8 to about 12 carbon
atoms.
The suitable anionic detergents include also the C.sub.8 to
C.sub.18 acyl sarcosinates (for example, sodium lauroyl
sarcosinate), sodium and potassium salts of the reaction product of
higher fatty acids containing 8 to 18 carbon atoms in the molecule
esterified with isethionic acid, and sodium and potassium salts of
the C.sub.8 to C.sub.18 acyl N-methyl taurides, for example, sodium
cocoyl methyl taurate and potassium stearoyl methyl taurate.
Anionic phosphate surfactants in which the anionic solubilizing
group attached to the hydrophobic group is an oxyacid of
phosphorous are also useful in the detergent compositions. Suitable
phosphate surfactants are the sodium, potassium, and ammonium alkyl
phosphate esters such as (R-O).sub.2 PO.sub.2 M and ROPO.sub.3
M.sub.2 in which R represents an alkyl chain containing from about
8 to 20 carbon atoms or an alkyl phenyl group having 8 to 20 carbon
atoms and M represents a soluble cation. The compounds formed by
including about 1 to 40 moles of ethylene oxide in the foregoing
esters, for example, [R-O(EtO)n].sub.2 PO.sub.2 M, are also
satisfactory.
The particular anionic detergent salt will be suitably selected,
depending upon the particular formulation and the proportions
therein. Suitable salts include the ammonium, substituted ammonium
(mono-, di-, and triethanolammonium), alkali metal (such as sodium
and potassium) and alkaline earth metal (such as calcium and
magnesium) salts. Preferred salts are the ammonium,
triethanolammonium, sodium, and potassium salts of the higher alkyl
sulfates and the C.sub.8 to C.sub.18 acyl sarcosinates.
The nonionic synthetic organic detergents are generally the
condensation product of an organic aliphatic or alkyl aromatic
hydrophobic compound and hydrophilic ethylene oxide groups.
Practically any hydrophobic compound having a carboxy, hydroxy,
amido, or amino group with a free hydrogen attached to the nitrogen
can be condensed with ethylene oxide or with the polyhydration
product thereof, polyethylene glycol, to form a nonionic detergent.
Further, the length of the polyetheneoxy chain can be adjusted to
achieve the desired balance between the hydrophobic and hydrophilic
elements.
The nonionic detergents include the polyethylene oxide condensate
of one mole of alkyl phenol containing from about 6 to 12 carbon
atoms in a straight- or branched-chain configuration with about 5
to 30 moles of ethylene oxide, for example, nonyl phenol condensed
with 9 moles of ethylene oxide, dodecyl phenol condensed with 15
moles of ethylene and dinonyl phenol condensed with 15 moles of
ethylene oxide. Condensation products of the corresponding alkyl
thiophenols with 5 to 30 moles of ethylene oxide are also
suitable.
Still other suitable nonionics are the polyoxyethylene
polyoxypropylene adducts of 1-butanol. The hydrophobe of these
anionics has a minimum molecular weight of 1,000 and consists of an
aliphatic monohydric alcohol containing from 1 to 8 carbon atoms to
which is attached a heteric chain of oxyethylene and oxypropylene.
The weight ratio of oxypropylene to oxyethylene covers the range of
95:5 to 85:15. Attached to this is the hydrophilic polyoxyethylene
chain which is from 44.4 to 54.6 of the total molecular weight.
Also included in the nonionic detergent class are the condensation
products of a higher alcohol containing about 8 to 18 carbon atoms
in a straight or branched-chain configuration condensed with about
5 to 30 moles of ethylene oxide. for example, lauryl-myristyl
alcohol condensed with about 16 moles of ethylene oxide.
A particularly useful group of nonionics is marketed under the
trade name "Pluronics." The compounds are formed by condensing
ethylene oxide with a hydrophobic base formed by the condensation
of propylene oxide with propylene glycol. The molecular weight of
the hydrophobic portion of the molecule is of the order of 950 to
4,000 and preferably 1,200 to 2,500. The addition of
polyoxyethylene radicals to the hydrophobic portion tends to
increase the solubility of the molecule as a whole. The molecular
weight of the block polymers varies from 1,000 to 15,000, and the
polyethylene oxide content may comprise 20 to 80 percent by
weight.
Zwitterionic detergents such as the betaines and sulfobetaines
having the following formula are also useful: ##SPC15##
wherein R is an alkyl group containing about 8 to 18 carbon atoms,
R.sub.2 and R.sub.3 are each an alkylene or hydroxyalkylene group
containing about 1 to 4 carbon atoms, R.sub.4 is an alkylene or
hydroxyalkylene group containing 1 to 4 carbon atoms, and X is C or
S:O. The alkyl group can contain one or more intermediate linkages
such as amido, ether, or polyether linkages or nonfunctional
substituents such as hydroxyl or halogen which do not substantially
affect the hydrophobic character of the group. When X is C, the
detergent is called a betaine; and when X is S:O, the detergent is
called a sulfobetaine or sultaine. Preferred betaine and
sulfobetaine detergents are 1-(lauryl dimethylammonio) acetate,
1-(myristyl dimethylammonio) propane-3-sulfonate, and
1-(myristyldimethylammonio)-2-hydroxy-propane-3-sulfonate.
The polar nonionic detergents are those in which the hydrophilic
group contains a semi-polar bond directly between two atoms, for
example, N.fwdarw.O, P.fwdarw.O, As.fwdarw.O, and S.fwdarw.O. There
is charge separation between the two directly bonded atoms, but the
detergent molecule bears no net charge and does not dissociate into
ions.
The polar nonionic detergents of this invention include open-chain
aliphatic amide oxides of the general formula R.sub.1 R.sub.2
R.sub.3 N.fwdarw.O. For the purpose of this invention R.sub.1 is an
alkyl, alkenyl, or monohydroxyalkyl radical having about 10 to 16
carbon atoms, R.sub.2 and R.sub.3 are each selected from the group
consisting of methyl, ethyl, propyl, ethanol, and propanol
radicals.
Other operable polar nonionic detergents are the openchain
aliphatic phosphine oxides having the general formula R.sub.1
R.sub.2 R.sub.3 P.fwdarw.O wherein R.sub.1 is an alkyl, alkenyl, or
monohydroxyalkyl radical ranging in chain length from 10 to 18
carbon atoms, and R.sub.2 and R.sub.3 are each alkyl and
monohydroxyalkyl radicals containing from 1 to 3 carbon atoms.
Examples of suitable ampholytic detergents include the alkyl
beta-aminopropionates, RN(H)C.sub.2 H.sub.4 COOM; the alkyl
betaiminodipropionates, RN(C.sub.2 H.sub.4 COOM).sub.2 ; the alkyl
and hydroxy alkyl taurinates, RN(CH.sub.3 )C.sub.2 H.sub.4 SO.sub.3
M; and the long-chain imidazole derivatives having the following
formulas: ##SPC16##
wherein R is an acyclic group of about 7 to 17 carbon atoms, W is
selected from the group of R.sub.2 OH, R.sub.2 COOM, and R.sub.2
OR.sub.2 COOM, Y is selected from the group consisting of
OH.sup.-,R.sub.3 OSO.sub.3 .sup.-,R.sub.2 is an alkylene or
hydroxyalkylene group containing 1 to 4 carbon atoms, R.sub.3 is
selected from the group consisting of alkyl, alkyl aryl and fatty
acyl glyceride groups having 6 to 18 carbon atoms in the alkyl or
an acyl group; and M is a water-soluble cation, for example,
sodium, potassium, ammonium, for alkylolammonium.
Formula I detergents are disclosed in Volume II of "Surface Active
Agents and Detergents" and Formula II detergents are described in
U.S. Pat. No. 2,773,068; U.S. Pat. No. 2,781,354; and U.S. Pat. No.
2,781,357. The acyclic groups may be derived from coconut oil fatty
acids (a mixture of fatty acids containing 8 to 18 carbon atoms),
lauric fatty acid, and oleic fatty acid, and the preferred groups
are C.sub.7 to C.sub.17 alkyl groups. Preferred detergents are
sodium N-lauryl beta-aminopropionate, disodium N-lauryl
iminodipropionate, and the disodium salt of 2-lauryl-cycloimidium
1-hydroxyl, 1-ethoxyethanoic acid, 1-ethanoic acid.
Cationic surface active agents may also be employed. Such agents
are those surface active detergent compounds which contain an
organic hydrophobic group and a cationic solubilizing group.
Typical cationic solubilizing groups are amine and quaternary
groups.
Examples of suitable synthetic cationic detergents are normal
primary amines RNH.sub.2 wherein R is C.sub.12 to C.sub.15 ; the
diamines such as those of the type RNHC.sub.2 H.sub.4 NH.sub.2
wherein R is an alkyl group of about 12 to 22 carbon atoms, such as
N-2-aminoethyl stearyl amine and N-2-aminoethyl myristyl amine;
amide-linked amines such as those of the type R.sub.1 CONHC.sub.2
H.sub.4 NH.sub.2 wherein R.sub.1 is an alkyl group of 8 to 20
carbon atoms, such as N-2-amino ethylstearyl amide and N-amino
ethylmyristyl amide; quaternary ammonium compounds wherein
typically one of the groups linked to the nitrogen atom is an alkyl
group of about 8 to 22 carbon atoms and three of the groups linked
to the nitrogen atom are alkyl groups which contain 1 to 3 carbon
atoms, including alkyl groups bearing inert substituents, such as
phenyl groups, and there is present an anion such as halogen,
acetate, methosulfate, etc. The alkyl group may contain
intermediate linkages such as amide which do not substantially
affect the hydrophobic character of the group, for example, stearyl
amido propyl quaternary ammonium chloride. Typical quaternary
ammonium detergents are ethyl-dimethyl-stearyl ammonium chloride,
benzyl-dimethylstearyl ammonium chloride, trimethyl-stearyl
ammonium chloride, trimethyl-cetyl ammonium bromide,
dimethyl-ethyl-lauryl ammonium chloride, dimethyl-propyl-myristyl
ammonium chloride, and the corresponding methosulfates and
acetates.
Preferred detergent compositions of this invention are the liquid,
antimicrobial shampoo compositions suitable for washing the hair
and scalp. Such compositions consist essentially of about 10 to 40
percent by weight of a detergent selected from the group consisting
of non-soap anionic, amphoteric, and zwitterionic detergents from
0.1 to 3 percent by weight of water-soluble or water-insoluble
particulate antimicrobial active material, 0.5 to 3.5 percent of
aminopolyureylene resin, and the balance primarly water. The
shampoo compositions may also include minor amounts of ethanol or
isopropanol perfume, color, stearate opacifying agents, ethylene
diamine tetracetate or citrate sequestering agents, thickening
agents, and fatty acid alkylolamide foam boosters.
Other detergent compositions falling within the scope of the
invention are the heavy-duty laundering compositions containing APU
polymers and at least one of the active materials potentiated by
the polaminopolyureylene resins, such as antibacterials,
fluorescent brighteners, and bluing agents. Such compositions
generally consist essentially of about 8 to 40 percent by weight of
non-soap anionic or nonionic detergent, about 0.1 to 3 percent by
weight of active material, about 0.5 to 3.5 percent by weight of
APU resin and the balance water-soluble inorganic or organic
builder salt. Suitable builders include sodium sulfate, sodium
carbonate, and sodium nitrilotriacetate as well as the
corresponding potassium compounds. Other compositions are sodium
carboxymethylcellulose, polyvinylalcohol, perfume, color, etc.
The foregoing laundering detergents may also be prepared in liquid
form. Suitable liquids consist essentially of about 5 to 20 percent
by weight of non-soap anionic or nonionic detergent, 10 to 25
percent by weight of potassium pyrophosphate, sodium silicate or
sodium nitrilotriacetate, 4 to 12 percent by weight of sodium or
potassium xylene or toluenesulfonate, 0.1 to 3.0 percent by weight
of active material, 0.5 to 3.5 percent by weight of APU resin, and
the balance primarily water. Suitable additives which may be added
are sodium carboxymethylcellulose, thickeners, color, and
perfume.
In bar form, the detergent material may be soap, anionic,
amphoteric, nonionic or mixtures of the foregoing detergents. In
addition to the usual proportions of APU resin and active material,
the bars may include color, perfume, free fatty acids, sodium
chloride, and fatty acid alkanolamide suds builders.
Each of the foregoing detergent compositions can be prepared by
methods well known in the art. For example, shampoos and built
liquid detergents are prepared by mixing, and particulate
laundering detergents are prepared by mixing, chemical drying or
spray drying.
The ability of the APU resins to potentiate the deposition of the
water-insoluble materials which function as antibacterial agents
onto proteinaceous substrates, such as hair and skin, is
demonstrated in the following radioactive substantivity test.
Substantivity is determined by stirring a 1.27-centimeter diameter
circular gelatin disk weighing about 40 milligrams for about five
minutes in 10 grams of an aqueous medium containing a known
concentration of radioactive tagged material such as zinc
2-pyridinethiol-1-oxide, rinsing the disk five times in 10
milliliters of water, drying, and measuring the radiation emission
with the aid of a radiation detector. The absolute degree of
deposition of the material is determined by comparing the observed
counts with the counts emitted by a known weight of the radioactive
material. The effect of APU resin on deposition can be readily
ascertained by repeating the test with a known weight of APU
present. Similarly, the effect of detergents can be quantitatively
measured by including detergents in the test composition.
The following examples are illustrative of the compositions falling
within the scope of this invention.
EXAMPLE 1
An aqueous dispersion of zinc 2-pyridinethiol-1-oxide is prepared
by dispersing 0.04 grams of radioactive zinc
2-pyridinethiol-1-oxide containing zinc 65 in one gram of water.
The resultant aqueous dispersion is diluted with 8.96 grams of
water with agitation, and the substantivity of the diluted
dispersion is determined using the foregoing substantivity
procedure. The results of the evaluation indicate 40.9 micrograms
of zinc-2-pyridinethiol-1-oxide are deposited on the disk from the
aqueous mixture containing 0.4 percent by weight of the
2-pyridinethiol-1-oxide. When the foregoing experiment is repeated
in the presence of an amino polyureylene resin (Resin A) having a
molecular weight of about 4,300 and the repeating unit
--(CH.sub.2).sub.3 N(CH.sub.3)(CH.sub.2).sub.3 N(H)C(O)N(H)--, 122
micrograms of zinc 2-pyridinethiol-1-oxide are deposited on the
disk at a concentration of 0.5 percent of said resin in the aqueous
test dispersion. Thus, the presence of 0.5 percent of APU resin
results in a 200 percent increase in the deposition of
zinc-2-pyridinethiol-1-oxide from an aqueous medium.
Use of a resin having a molecular weight of about 5,600 and
N,N'-di(3-aminopropyl) piperazine as the repeating unit in the
foregoing test yields comparable results.
EXAMPLE 2
When the procedure of Example 1 is repeated using an aqueous
solution of 0.25 percent by weight of radioactive (C-14) cetyl
trimethylammonium bromide (CTAB) at pH 4.5 as the test medium, 294
micrograms of CTAB are deposited on the gelatin disk. Repetition of
this test in the presence of 0.75 percent by weight of the APU
resin used in Example 1 results in the deposition of 679 micrograms
of CTAB, an increase in deposition of about 130 percent. When the
pH of the test solution is increased to 8.5, a deposition of 259
micrograms of CTAB is obtained in the absence of APU resin and a
deposition of 734 micrograms is obtained in the presence of 3
percent by weight of the APU resin of Example 1. Thus, a 180
percent increase in deposition of CTAB is noted at pH 8.5.
EXAMPLE 3
Example 2 is repeated with the exception that a 10 percent aqueous
ethanol mixture is substituted for water in the test solution and
the pH is adjusted to 6.5. A deposition value of 202 micrograms of
CTAB is noted in the absence of APU resin, and a deposition value
of 643 micrograms of CTAB is noted in the presence of 0.73 percent
by weight of the APU resin of Example 1. This represents an
increase in deposition of about 220 percent. For comparison, only
227 micrograms of CTAB are deposited when the concentration of CTAB
in the test solution is increased to 1 percent by weight. Thus, the
APU resin is significantly more effective in enhancing deposition
than an increase in the CTAB concentration from 0.25 to 1 percent,
a 300 percent increase.
EXAMPLE 4
When the procedure of Example 1 is repeated using a 0.5
percent-by-weight aqueous alcoholic (70%) dispersion of radioactive
(C-14) bis(3,5,6 trichloro-2-hydroxyphenyl) methane as the test
solution, the radioactivity of the gelatin disk averages 2,100
counts per minute (cpm.) Repetition of the test in the presence of
1.25% concentration of the APU resin of Example 1 results in an
average radioactivity of 13,200 cpm. Thus, the presence ot the APU
resin increases the deposition of the antimicrobial compound by
about 500%. Substantially similar results are noted when either
lamb skin or human callus tissue is substituted for the gelatin
disk in the foregoing experiment.
The APU resin of Example 1 can be replaced by either a resin having
a molecular weight of about 4,600 and the repeating unit
--CH.sub.2).sub.3 N.sup.+(CH.sub.3).sub.2 (CH.sub.2).sub.3
NHC(O)NH-- or a resin having a molecular weight of about 6,700 and
the repeating unit ##SPC17##
with substantially similar results. Similarly, the substituted
methane may be substituted with 5-chloro-2(2,4dichlorophenoxy)
phenol with substantially similar results.
EXAMPLE 5
Tests of the following shampoo illustrate the improved effects
attributable to the APU resin. This shampoo is effective to inhibit
the growth of Pityrosporum ovale.

When the foregoing composition is formulated with a radioactive
zinc 2-pyridinethiol-1-oxide (Zn 65) material and is evaluated
using the substantivity procedures of Example 1, 20.8 micrograms of
radioactive zinc 2-pyridinethiol-1-oxide are noted on the gelatin
disk. In this evaluation, 2.5 grams of shampoo are diluted with 7.5
grams of water to simulate normal use dilution of shampoos, and the
diluted shampoo is test solution. Under such conditions, the
concentration of zinc 2-pyridinethiol-1-oxide in the test solution
is 0.4 percent by weight, and the concentration of APU resin is 0.5
percent by weight. Repetition of the foregoing test with an
identical composition not containing APU resin results in the
deposition of 8.7 micrograms of zinc 2-pyridinethiol-1-oxide. Thus,
use of APU resin in combination with zinc 2-pyridinethiol-1-oxide
in the presence of detergents results in an increase in deposition
of about 140 percent.
To confirm that increased deposition results in enhanced residual
activity, radioactive disks obtained using the foregoing evaluation
technique are plated in a standard agar medium inoculated with P.
ovale, and the diameters of the zone of inhibition are measured
after 24 hours of incubation. These results are shown in Table I
together with results of non-radioactive disks. Resin A alone has
no zone of inhibition.

The foregoing results indicate that APU resin significantly
improves the antibacterial effectiveness of the zinc
2-pyridinethiol-1-oxide. Further, the results show that
radioactivity has a minimal effect on the results.
The effect of APU resin on long-standing activity is illustrated by
repeatedly transferring the radioactivity disks of Table I to
freshly seeded agar plates inoculated with P. ovale for additional
incubation periods after measuring the zone of inhibition. Results
are set forth in Table II.

EXAMPLE 6
Example 5 is repeated with the exception that the concentration of
zinc 2-pyridinethiol-1-oxide in the shampoo is reduced to 0.4
percent. 17.4 micrograms of zinc 2-pyridinethiol-1-oxide are
deposited on the disk. In the absence of the 2 percent of APU
resin, 6.1 micrograms of zinc 2-pyridinethiol-1-oxide are deposited
on the disk. Again, APU resin significantly enhances the deposit of
zinc 2-pyridinethiol-1-oxide on a proteinaceous substrate.

When the composition is formulated with radioactive sodium
2-pyridinethiol-1-oxide, the zone of inhibition determined as
described in Example 5, the gelatin disk exhibits a halo diameter
of 54.2 m.m. when tested against P. ovale. In the absence of APU
resin, a halo diameter of 37.5 m.m. is observed. These results show
that APU resin improves the effectiveness of the water-soluble
sodium 2-pyridinethiol-1-oxide material as well as the
water-insoluble zinc-2-pyridinethiol-1 oxide.

When the foregoing composition is formulated with a radioactive
(C-14 tagged) tribromosalicylanilide and the deposition evaluated
as described in Example 1, 1.5 micrograms of antibacterial agent
are noted on the gelatin disk. As only 0.5 micrograms are deposited
in the absence of the APU resin, use of the APU resin increases
deposit by 200 percent.
EXAMPLE 9
Substitution of 1 percent of trichlorocarbanilide for the

substantially similar results.

substantially similar results are obtained.
Other compositions exhibiting improved effectiveness because of the
presence of an aminopolyureylene resin therein follow:
EXAMPLE 13
A heavy-duty liquid detergent composition having improved
resistance to color fading because of ultraviolet light
follows:
% by weight Sodium tridecylbenzene sulfonate 10.0 Potassium xylene
sulfonate 8.5 Lauric-myristic diethanolamide 4.5 Potassium
pyrophosphate 15.0 Sodium carboxymethylcellulose 0.5 2,4
dihydroxybenzophenone 0.05 Hydrogenated castor oil 0.5 Resin A 0.5
Water balance 100.0
2,2'hydroxy4,4'dimethoxybenzophenone may be substituted for the
benzophenone in the composition of Example 13 with substantially
similar improved effects.
EXAMPLE 14
A built particulate laundry detergent composition exhibiting
improved antibacterial effectiveness has the following
composition:
% by weight Sodium tridecylbenzene sulfonate 17.5 Sodium
tripolyphosphate 40.0 Sodium silicate (1Na.sub.2 O:2.35SiO.sub.2)
7.0 Sodium sulfate 23.1 Tribromosalicylanilide 0.4 Resin A 3.0
Sodium carboxymethylcellulose 0.5 Water 8.5 100.0
Fabrics laundered in the foregoing composition exhibit improved
antimicrobial effectiveness.
EXAMPLE 15
A detergent bar composition exhibiting improved resistance to
copper discoloration has the following composition.
______________________________________ % by weight Sodium N lauryl
B iminodipropionate 8.75 Sodium C.sub.10 to C.sub.20 alkane
sulfonate 24.25 Sodium tallow soap 26.40 Sodium tridecylbenzene
sulfonate 7.30 Syrupy phosphoric acid (85%) 7.30 Stearic Acid 3.60
Benzotriazole 0.5 Resin A 4.0 Water balance 100.00
______________________________________
Ethylene thiourea may be substituted for benzotriazole in the
composition of Example 15 with substantially similar results.
While the improved properties appear to be due primarily to
enhanced deposition and/or retention of both water-soluble and
water-insoluble materials due to the presence of the
aminopolyureylene resin in the compositions, the actual mechanism
is not completely understood. Accordingly, applicant does not wish
to be bound by any particular scientific theory or explanation.
While compositions containing APU resin and an active material may
be prepared by admixing resin and active material in any suitable
manner, in the preparation of detergent containing compositions,
improved effects are obtained when the resin and active material
are premixed before admixing with the detergent component.
Although the present invention has been described with reference to
particular embodiments and examples, it will be apparent to those
skilled in the art that similar results may be obtained when the
aminopolyureylene resin is used in combination with a wide variety
of water-soluble and water-insoluble substances in addition to
those specifically described.
