[0001] 1. Field of the Invention
[0002] The present invention relates to novel oat-lipid based
surfactants and derivatives, and emollients, their process of
manufacture, their use in the production of surface active
derivatives, non-surface active esters, and ester emollients, and
skin and hair care preparations containing the surfactants,
derivatives, and emollients. The surfactants and fatty ester
derivatives are useful as emollients, dispersants, emulsifiers, and
conditioners for hair care and skin care products.
[0003] 2. Description of the Related Art
[0004] Surfactants and derivatives are known for a variety of
different applications for cosmetic, pharmaceutical, and medicinal
purposes.
[0005] Numerous references describe the production and use of
surface active derivatives or non-surface active esters, and ester
emollients. For example, it is known to use oats and oat extract in
cosmetic preparations to obtain the benefits of mildness,

useful as emollients, dispersants, emulsifiers and conditioners for
hair and skin care products are commonly produced from a wide
variety of fatty acids, fatty alcohols and amines, polyamines,
dialkyl propylamines, alkanolamines, etc. However, none of these
references teach or suggest the specific novel oat-based
surfactants made from the fatty oil triglyceride obtained from
oats, or OFTG, of this invention or the use of OFTG to produce
surface active derivatives or non-surface active esters, and ester
emollients for cosmetics and personal care products.

DETAILED DESCRIPTION OF THE INVENTION
[0033] Major fatty raw materials are fatty triglycerides from
sources which are naturally renewable such as coconut oil, soybean
oil, castor oil, sunflower oil, corn oil, canola oil, etc. A
preferred source is oat seeds.
[0034] The surfactants and derivatives and emollients of the
invention are made from the fatty oil triglyceride obtained from
oats. Such fatty oil triglyceride is called "oat extract" because
it is the raw material obtained by extraction of oat seeds of Avena
Sativa with organic solvents.
[0035] Oat seeds may be refined, unrefined, or minimally refined,
as disclosed in U.S. Pat. Nos. 5,622,690 and 5,620,692 to Potter et
al., incorporated herein by reference, to free the proteinaceous
matter from the lipids. The lipid portion is called "oat extract",
"oat fatty oil" or "oat fatty triglyceride", abbreviated herein as
"OFTG", commercially available from Nurture, Inc., of Missoula,
Mont. as Microat.RTM. afa Complex.
[0036] Oat Fatty Triglyceride (OFTG) is essentially made up of
saturated and unsaturated fatty acids along with some free fatty
acids. It is well known that OFTG contains a high level of natural
potent antioxidants, such as an ester of ferulic acid. This
compound is structurally similar to the synthetic antioxidants
butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT).
Additionally, OFTG from oat extract contains tocols including
tocopherols and tocotrienols. Furthermore, OFTG contains the three
forms of Vitamin E (alpha-, gamma- & delta-tocopherols). It is
also known that OFTG contains phenols and phospholipids which
behave as antioxidants. Antioxidants scavenge and neutralize free
radicals created by normal metabolism or damage to skin cells which
may result from exposure to ultraviolet radiation, inflammation,
dry skin, psoriasis, dermatitis, burns, and aging. This is useful
to prevent and/or treat skin inflammation, aging, and other skin
and hair damage mediated by free radicals.
[0037] The composition of fatty moieties in OFTG is as follows:
Linoleic Acid comprises 38%-42%; Oleic Acid comprises 38%-42%; and
Palmitic Acid comprises 14%-17% of the total fatty acid content.
Free fatty acids are typically present at 8%. The fatty acid
composition profile is of importance because it is close to that of
the principal constituents of human skin surface lipids that play a
key role in maintaining the normal barrier function of healthy
skin.
[0038] Surfactants and fatty derivatives useful as emollients,
dispersants, emulsifiers, and conditioners for hair and skin care
products are commonly produced from a wide variety of fatty acids,
fatty alcohols and amines, polyamines, dialkyl propylamines,
alkanolamines, etc. Unless otherwise specified herein, the term
"derivatives" is a broad term meant to include surfactants,
non-surface active esters, and ester emollients.
[0039] The following list of reactants and their respective
derivatives such as esters, amides, betaines, quaternaries, etc.,
is exemplary of the type of reactants and derivatives on which the
emollient surfactants and derivatives may be based, and, as such,
is not to be considered limiting.
[0040] Group A (Reactants): Fatty acids or methyl esters of fatty
acids or fatty oils sourced from naturally renewable fatty
triglycerides of oats. A preferred source is oat seeds for
oat-based triglycerides.
[0041] Group B (Reactants) may be selected from the group
consisting of: Alkanolamines such as Monoethanolamine,
Diethanolamine; Dialkylaminopropylamines such as Dimethyl
Aminopropyl Amine; Polyamines such as Diethylene Triamine,
Triethylene Tetramine; Primary and Secondary amines; and Fatty
Alcohols (linear and/or branched) (C8-C22 alcohols).
[0042] The preferred reactants used in preparing the surfactants
and derivatives of the invention are selected from the group
consisting of:

[0053] The most preferred reactants are A, E, G, H, I and J.
[0054] Reactants A and B are used in either exact stoichiometric
proportions, or Reactant A (that is, OFTG) is used in some excess
over Reactant B, so that there is no or negligible amounts of free
Reactant B as residual in the finished product of the
invention.
[0055] The novel oat lipid based surfactants and derivatives

[0068] For example, derivatives such as amides of
OFTG/Monoethanolamine; Acyl Amidopropyl Dimethyl Amines of OFTG as
Cationic Surfactants; Betaines based on OFTG; Esters of OFTG based
Fatty Acids and Isostearyl Alcohol; Quaternaries based on OFTG

those involving other reactive groups known to those skilled in the
art.
[0069] In a specific embodiment, and by way of illustration, this
invention contemplates the production of the following surfactants
and derivatives:
[0070] 1. NATRLFINE.RTM. A (proposed INCI name: oat-amide-MEA) is
the reaction product of OFTG and Monoethanolamine. It is also
called OatFattyAmide of Monoethanolamine. It has the following
structure: 1
[0071] where R=oat fatty acids group.
[0072] 2. NATRLFINE.RTM. T-1 (proposed INCI name: OAT-AMIDE-MEA and
Sodium Cocoyl Methyl Taurate) is a blend or mixture of
NATRLFINE.RTM. A and Sodium Cocoyl Methyl Taurate.
[0073] The structure of Sodium Cocoyl Methyl Taurate is: 2
[0074] where R=Cocoyl group.
[0075] 3. NATRLFINE.RTM. MD (whose proposed INCI name is
oatamidopropyldimethylamine) is the reaction product of OFTG and
Dimethylaminopropylamine. It has the following structure: 3
[0076] where R=Oat Fatty Acids group.
[0077] 4. NATRLFINE.RTM. E-18 (proposed INCI name: IsoStearyl Oat
Fatty Ester) is the reaction product of OFTG Methylated and
IsoStearyl Alcohol. It has the following structure: 4
[0078] where R.sub.1=Oat Fatty Acids group; and R.sub.2=IsoStearyl
Group.
[0079] 5. NATRLFINE.RTM. AB-40 (proposed INCI name:
oatamidopropylbetaine) is a betaine of oatamidopropyldimethylamine
ester having the following structure: 5
[0080] where R=Oat Fatty Acids group.
[0081] 6. NATRLFINE.RTM. SS (proposed INCI name: Disodium
Oat-Amide-MEA-Sulfosuccinate) is the reaction product of Oat
Amide-MEA-Maleate and Sodium Sulfite. It has the following
structure: 6
[0082] where R=Oat Fatty Acids group.
[0083] 7. NATRLFINE.RTM. Q (proposed INCI name:
Oat-AmidopropylDimethyl Ethyl Ethosulfate) is a reaction product of
oatamidopropyl dimethyl amine and diethylsulfate having the
following structure: 7
[0084] where R=Oat Fatty Acids group.
[0085] The derivatives have shown usefulness similar to
conventional amides and betaines with the additional benefits of
being mild to the skin. Also, skin feel is even better than using
conventional derivatives.
[0086] Some of these surfactants and derivatives are used in skin
care and hair care formulations and dermatological preparations.
Personal care formulations prepared according to the invention,
which contain the surfactants and derivatives added thereto, can be
formed, without limitation, into applications such as solutions,
emulsions, gels, solids, emulsions, aerosols, powders, creams,
granules, or tablets.
[0087] Mildness and emolliency of these derivatives is of
importance to the improved skin and hair care products including
the surfactants and derivatives of the invention. The inherent
presence of natural antioxidants and vitamin factors is the
distinct difference in the use of OFTG as opposed to other commonly
used fatty triglycerides. One other major aspect of derivatives of
this invention is their very, very low to negligible toxicological
effects indicating their mildness to skin care products.
[0088] Thus, the advantages of the derivatives of the invention
include:
[0089] Made from naturally renewable source
[0090] Mildness of the derivatives
[0091] Possible antioxidancy activity
[0092] Mildness of the formulations containing the derivatives
[0093] Very low toxicological profile
[0094] Low irritation
[0095] Thus, the novel oat-based surfactants and derivatives of
this invention have unique properties in that they are mild to the
skin, have very low to negligible toxicological effects, and
natural antioxidants and vitamin factors are inherently present.
These properties make these derivatives useful as a vehicle or
carrier, dispersants, emulsifiers, emollient, solubilizer and
conditioners for skin care and hair care formulations such as hair
creams, hand cleaners, bath oils, suntan oils, anti-perspirants,
perfumes, colognes, cold creams, electric pre-shaves, eye and
throat oils, finger nail polish, topical pharmaceutical ointments,
lipsticks, stick rouge, skin lotions and creams, skin moisturizers,
cleansing creams, and after-bath splash and lotions, as well as
other formulations. The foregoing list is only exemplary of the
type of compositions in which the oat-based surfactants and
derivatives of this invention may be used, and, as such, is not to
be considered limiting.
[0096] The amount of such oat-based surfactants and derivatives to
be used in such compositions is dependent on the type of hair care
and skin care compositions, the desired dosage or amount of active
ingredient to be delivered, the type and quantity of other
ingredients, such as cosmetic ingredients used, the amount and type
of functional additives that are utilized, the user's skin and hair
type, and the severity and extent of the skin or hair condition,
and other parameters that will be apparent to those skilled in the
art. Generally, compositions containing the oat-based surfactants
and derivatives of the invention are topically applied in effective
amounts to the affected areas of the skin or to hair. Typically,
the amount of surfactants and derivatives used ranges from about
1.0% to about 30.0%, by weight, of the skin care compositions. For
example, a facial cream may only have about 5.0%, while a massage
oil may have up to about 20% by weight. Still higher amounts may be
used in, for example, bath oils, e.g. 50%.
[0097] Further, the oat-based surfactants and derivatives of this
invention possess other unusual physio-chemical properties, which
can make them suitable for use as solvents and emollient carriers
in cosmetic formulations, and for use as solvents and emollient
carriers in general cleaning compositions, such as in hand, face,
and body creams and lotions. Thus, the oat-based surfactants and
derivatives described herein may serve not only as emollients and
carriers, but may also exhibit one or more other functions.
[0098] The surfactants and derivatives of the invention have
properties such as, being less greasy, less oily, low toxicity,
ease of emulsification, acid and alkaline stability, the ability to
form gels with suspending agents, water solubility/dispersibility,
and the ability to act as solvents for many common skin and hair
care ingredients.
[0099] The following are non-limiting examples of processes for
preparing the surfactant and derivative compositions of the
invention (Examples 1 to 11), toxicology results for several of
said compositions (Example 12), as well as uses of the compositions
in specific cosmetic or personal care product formulations
(Examples 13 to 19). In the Examples, as well as throughout this
application, the chemical and scientific symbols have their
customary meanings and all percents are weight percents unless
otherwise specified.
[0100] Example Nos. 1 through 11 identify surfactants and
derivatives produced by the process of the invention. For ease of
identification, each ester is identified by both an Example Number
and a Reference No., where applicable. This identification system
is used in the subsequent Tables Nos. I through VII, as set forth
in Examples 13 through 19.
[0101] Although the Examples use only selected compounds and
formulations, it should be understood that the examples are
illustrative and not limited. Thus, any of the aforementioned
Reactants A and B may be substituted according to the teachings of
this invention in the following Examples.

[0114] Preparation of Fluid Delivery System for Oat-Amide-MEA of
Example #1 (Trade Name NATRLFINE.RTM. T-1) (INCI Name:
Oat-Amide-MEA and Sodium Cocoyl Methyl Taurate)
[0115] The solid amide of Example #1 is Oat-Amide-MEA. In this
Example, the amide is blended with aqueous solution of
Sodium-N-Methyl-N-Cocoyl Taurate resulting in a fluid, flowable
dispersion paste. Thus, 8 gms. of Oat-Amide-MEA of Example #1 was
mixed at 70.degree. C. with a mixture of 70 gms. of
Sodium-N-Methyl-N-Cocoyl Taurate (TAURANOL.RTM. WS CONC. from
Finetex, Inc. of Elmwood Park, N.J.) and 22 gms. of water. A smooth
off-white paste with very good flow was obtained upon cooling with
mixing.
EXAMPLE #6 (117-54)

of water and 80 gms. Oat-Amide-MEA of Example #1 were mixed at
80.degree. C.-85.degree. C. All of the solid particulate matter
dissolved, giving an amber gel at 40.degree. C. Upon cooling, a
smooth off-white paste was obtained. Collected yield was 995 gms.
of this mixture.
EXAMPLE #7 (117-38)
[0118] Amido Amine of OFTG and Dimethyl Amino Propyl Amine Trade
Name: NATRLFINE.RTM. MD (Proposed INCI Name:
Oat-Amidopropyldimethylmine)
[0119] 426 gms. of Oat Fatty Triglyceride (OFTG) was charged to 1
liter reaction flask with distillation assembly. To this, under
nitrogen, was added, at 70.degree. C., 162 gms. of Dimethyl Amino
Propyl Amine (DMAPA) and 12 gms. Sodium Methylate 25% in Methanol.
This mass was heated further to 150.degree. C. and reacted over a
period of about 5 hours. The final alkalinity was 142 mg KOH/g
which resulted after applying a vacuum to remove the free DMAPA.
The distillate collected was 25.50 gms. which was mostly DMAPA. The
yield of this amido amine product of this reaction was 551 gms. and
a residue of approximately 37 gms of by product. Thus the total was
588 gms. as collected yield.
EXAMPLE #8 (117-40)
[0120] Processing of Residue of Example #7
[0121] The high titer residue of Example #7 was diluted with water
in the ratio of 37 gms. residue and 870 gms. water, totaling 907
gms. of the mixture.
[0122] A. The above mixture was a thin dispersion that showed a
tremendous lubricity on skin when cleaning the hands under tap
water. The dispersion has a slight viscous body to the mass. The
dispersion also has a gelatinous flow indicating similarity to that
shown by B-Glucan containing starches/proteins originating from
oats, as is known in the art.
[0123] B. The dispersion was mixed in a 1:1 ratio with cocobetaine
(McIntyre Group, University Park, Ill.) and was a clear solution
with small gelatinous particles which easily disperse. This mixture
gave excellent foaming for washing under tap water and left a
smooth, silky feel on hands, especially on dry hands.
[0124] C. The dispersion was also cleared with minor additions of
citric acid. Such clear solution also gave excellent foaming under
tap water and hands washed with this clear liquid had distinct
softer feel when wet and also when dry.
[0125] D. The dispersion, upon standing, shows sedimentation which
re-disperses upon mixing. Also, the addition of citric acid permits
the dispersion to become a clear liquid.
[0126] The exhibited properties indicate the derivative of the
reaction of Example #7 is the major component of this
dispersion.

sodium monochloroacetate was dissolved. The solution was then
heated and brought to 60.degree. C. To this was then added 131.64
gms. of the amido amine product of Example #7. The temperature was
brought to and maintained at 83.degree. C.-85.degree. C. The
mixture was a thick paste. An additional 200 gms. water and 103
gms. 1,3-Butylene Glycol was added to fluidize the same. The
reaction was maintained at 80.degree. C.-85.degree. C. for about
4-5 hours. The reaction showed 2.86% sodium chloride and 60%
moisture as water by Karl Fisher titration. The yield was 733 gms.
