Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application is a continuation-in-part of application
Ser. No. 10/450,137 previously filed in U.S., relating to a
detergent comprising limonene and ethanol.
BACKGROUND OF THE INVENTION
[0002] (1) Field of Invention
[0003] The present invention relates to a method for cleaning an
article to be cleaned with oily deposits. More particularly, it
relates to an efficient method for cleaning the floor of deposited
synthetic resin wax and the like without collecting dirty water by
using a detergent comprising 25.about.80% by weight of (A) a
terpene-based hydrocarbon and/or hydrocarbon-based solvent having a
solubility parameter of 8.0.about.9.8 and 75.about.20% by weight of
(B) an alcohol including one or more hydroxyl groups and having a
solubility parameter of 10.about.15.
[0004] (2) Description of Related Art
[0005] In convenience stores, supermarkets, office buildings and
the like, synthetic resin wax and the like have been coated mostly
on the chemical tile-paved or stone-built floor as a grazing agent
to provide safeguard for the floor. As time goes by, however, the
coated synthetic resin wax and the like have appeared shabby with
scratches or stains resulting from treading of the people. The
blemished synthetic resin wax and the like have been removed by
cleaning and a new coat of them has been provided to get the floor
to regain the beauty it had once.
[0006] The floor is cleaned by brushing with the use of a detergent
and removing coated synthetic resin wax and the like therefrom.
Conventional detergents contain alkaline substances as the chief
ingredient, plus a great deal of surfactants and builders. When
these conventional detergents are used, incidental works cost much
labor. Dirty water caused by washing of the floor is collected
before recoating of synthetic resin wax and the like, while
hangovers on the floor are disposed of and residual alkaline
substances are neutralized thereafter. Particularly, collection of
dirty water is a big problem calling for a quick solution, combined
with a problem of drainage.
[0007] Meanwhile, JP-A-7-278589, JP-A-11-92795, JP-A-6-511267,
JP-A-2000-303095 and JP-A-4-173900 disclose the detergent
compositions comprising terpene-based hydrocarbon such as limonene.
But it is not disclosed that the same compositions can be used as
the detergent of the articles to be cleaned against coated
synthetic resin wax and the like. JP-A-5-140596 and
JP-A-2000-311093 disclose the detergents for use in floors coated
with synthetic resin wax and the like but the disclosed
compositions are entirely different from the detergent compositions
of the present invention.
[0008] In JP-A-2004-035651, the present inventors have proposed a
method that the floor detergent composition comprising
terpene-based hydrocarbon and ethanol is used by diluting it in
several times as much water. According to this method, however, it
is necessary to allow the detergent composition to take long in
infiltrating into the synthetic resin wax and the like, and an
improvement of the method has been desired from the viewpoint of
cleaning efficiency.
BRIEF SUMMARY OF THE INVENTION
[0009] An object of the present invention is to provide an
efficient method for cleaning an article to be cleaned of deposited
synthetic resin wax and the like in an easy and time-saving
procedure. The method has improved poor workability in collection
of dirty water, disposal of floor hangovers and the like as
observed in conventional detergents.
[0010] The present inventors have made an intensive investigation
in an effort to find a solution in the above-mentioned problems. As
a result, it has been found that the deposited synthetic resin wax
and the like can efficiently be released and withdrawn from an
article to be cleaned without collecting dirty water by using a
particular release agent. This release agent is prepared of one
solvent having a solubility parameter of 8.0.about.9.8 and another
having a solubility parameter of 10.about.15 to deal with deposited
synthetic resin wax and the like on the article to be cleaned. With
these findings, the present invention has been brought to
completion.
[0011] The present invention provides:
[0012] [1] A method for cleaning an article to be cleaned with oily
deposits by using a detergent comprising 25.about.80% by weight of
(A) a terpene-based hydrocarbon and/or hydrocarbon-based solvent
having a solubility parameter of 8.0.about.9.8 and 75.about.20% by
weight of (B) an alcohol including one or more hydroxyl groups and
having a solubility parameter of 10.about.15, wherein the detergent
in a state of having a water content of 10% by weight or less is
coated onto the article to be cleaned and then causes oily deposits
to release from said article.
[0013] [2] A method for cleaning as set forth in [1], wherein said
detergent is made to have a water content of 10% by weight or less
without diluting it with water or with diluting it with water or a
mixed solution of water and a surfactant and then the resultant
detergent is coated onto the article to be cleaned.
[0014] [3] A method for cleaning as set forth in [1] or [2],
wherein either 25.about.80% by weight of (A) a terpene-based
hydrocarbon and/or hydrocarbon-based solvent having a solubility
parameter of 8.0.about.9.8 or 75.about.20% by weight of (B) an
alcohol including one or more hydroxyl groups and having a
solubility parameter of 10.about.15 is coated each singly or both
of them are coated as a mixture onto the article to be cleaned.
[0015] [4] A method for cleaning as set forth in any of
[1].about.[3], wherein said terpene-based hydrocarbon is one kind
or more selected from the group consisting of d-limonene,
l-limonene and dl-limonene.
[0016] [5] A method for cleaning as set forth in any of
[1].about.[3], wherein said alcohol is one kind or more selected
from the group consisting of methanol, ethanol, isopropanol,
n-propanol and denatured alcohol.
[0017] [6] A method for cleaning as set forth in any of
[1].about.[5], wherein said article to be cleaned with oily
deposits is a floor deposited with synthetic resin wax.
[0018] [7] A method for cleaning as set forth in any of
[1].about.[6], wherein said detergent is coated onto the floor
deposited with synthetic resin wax and the deposited wax is
released using a wax releasing device within 3 minutes thereafter
while the detergent remains wet.
[0019] [8] A method for cleaning as set forth in [7], wherein one
kind or more selected from the group consisting polisher, rolling
cleaner, handy cleaner and brush is used as said wax releasing
device.
[0020] [9] A method for cleaning as set forth in [8], wherein a
polisher into which a floor brush is fitted is used as said wax
releasing device to release wax in the shape of a powder.
[0021] Different from the ordinary methods for cleaning by diluting
the commercially available detergents in several times as much
water, the cleaning method of the present invention does not call
for collection of dirty water. After the detergent is coated on the
article to be cleaned, the cleaning method of the present invention
can release wax with a wax releasing device while the detergent
remains wet without giving the time for its infiltration.
Practically, the cleaning method of the present invention does not
need to leave the detergent to stand for long after coating,
finishing with the polishing operation and that of disposing of
released substances within a shorter span of time. Thus, the method
of the present invention is really efficient in cleaning the
article to be cleaned of deposited synthetic resin wax and the
like.
DETAILED DESCRIPTION OF THE INVENTION
[0022] The present invention will be specifically explained
below.
[0023] The present invention relates to a method for cleaning an
article to be cleaned of deposited synthetic resin wax and the like
by using a detergent comprising 25.about.80% by weight of (A) a
terpene-based hydrocarbon and/or hydrocarbon-based solvent having a
solubility parameter of 8.0.about.9.8, preferably 8.1.about.9.0 and
75.about.20% by weight of (B) an alcohol including one or more
hydroxyl groups and having a solubility parameter of 10.about.15.
As (A) the terpene-based hydrocarbons and/or hydrocarbon-based
solvents having the solubility parameter of 8.0.about.9.8, those
commercially available at industrially reasonable prices are
preferable. Their preferable examples are hydrocarbon-based
solvents such as xylene, toluene and the like and terpene-based
hydrocarbons. Among them, terpene-based hydrocarbons and/or
hydrocarbon-based solvents having the solubility parameter in a
range of 8.1.about.9.0 are most preferable. Examples of
terpene-based hydrocarbon include myrcene, selenium, ocimene,
pinene, limonene, camphene, terpinolene, tricyclene, terpinene,
fenchene, phellandrene, silvesthrene, sabinane, p-menthene-1,
p-menthene-3, p-thymine, p-menthane and the like. Among them
.alpha.-pinene, .beta.-pinene, limonene, p-menthen-1, p-menthene-3,
p-thymine and p-menthane are more preferable and limonene is most
preferable. Examples of limonene to be used in the present
invention includes synthetic limonene, natural limonene, natural
essential oil containing limonene as the chief ingredient, for
example, orange oil, lemon oil, grapefruit oil, mandarin oil,
tangerine oil and the like. An essential oil containing d-limonene
of citrus origin as the chief ingredient is more preferable from
the viewpoint of environmentology.
[0024] As (B) alcohol including one or more hydroxyl groups and
having the solubility parameter of 10.about.15, preferably
10.about.13 for use in the present invention, those available at
industrially reasonable price are preferable. As alcohols including
one or more hydroxyl groups, those under-mentioned can be cited.
Aliphatic alcohols including one hydroxyl group are methanol,
ethanol, denatured alcohol, propanol, butanol, pentanol, hexanol,
heptanol, octanol, dodecanol, cyclohexanol and the like. Aliphatic
alcohols including two hydroxyl groups are ethylene glycol,
propylene glycol, trimethylene glycol, triethylene glycol,
tetraethylene glycol, liquid polyethylene glycol, diethylene
glycol, dipropylene glycol and the like. Aliphatic alcohols
including three hydroxyl groups are glycerin and the like. There
are other alcohols such as diethylene glycol monomethyl ether,
diethylene glycol monoethyl ether and the like. Among them,
ethanol, methanol, isopropanol, denatured alcohol and their mixed
alcohol are preferable because they are industrially produced in
great quantities and easy to use at the reasonable prices. It is
occasionally necessary to improve some of these alcohols in the
matter of ignition point and odor in the process of really
incorporating them into the detergents. Alcohols having the
ignition point higher than 20.degree. C., for example, 1-butanol,
1-pentanol, ethylene glycol, propylene glycol, diethylene glycol
and the like are safe to use. As regards odor, ethylene glycol,
propylene glycol and diethylene glycol are preferable. One kind or
more selected from the group consisting of ethylene glycol,
propylene glycol and diethylene glycol can be mixed with other
aliphatic alcohol, for example, ethanol, denatured alcohol,
1-propanol, 2-propanol, 1-butanol and the like. The so obtained
mixtures are preferable from the viewpoint of workability of floor
cleaning, ignition point and odor and the like.
[0025] In the cleaning methods of the present invention, one
solvent having solubility parameter of 8.0.about.9.8 and another
having solubility parameter of 10.about.15 are blended at a ratio
of, preferably 25.about.80 parts by weight:75.about.20 parts by
weight, more preferably 25.about.50 parts by weight:75.about.50
parts by weight to 100 parts by weight totaling the solvents. The
blending ratio is important to get deposited synthetic resin wax to
release from the article to be cleaned in the shape of a
powder.
[0026] In the cleaning methods of the present invention, the
solvents are mostly used indoor, arousing the consciousness of
offending odor occasionally. In such an event, one kind or more
selected from the group consisting deodorant, deodorizer, odor
preventing agent and aromatic are preferably introduced into the
above-mentioned compositions. With these additives, the cleaning
people can work comfortably, continuing the cleaning operation
without a hitch. As the deodorant, deodorizer, odor preventing
agent and aromatic, a great many substances are known, derived from
the organic or inorganic families, plant origin or biochemical
background or detergent series. They are for use in living rooms or
bath rooms or to deal with garbage, to take care of household
animals or to dispose of tobacco odor, classified into sensory
deodorization, chemical deodorization, physical deodorization,
biological deodorization and the like. All these substances can be
used in the present invention as far as they make the cleaning
people's work comfortable. The deodorant, deodorizer, odor
preventing agent and aromatic are supplied by many manufacturers
such as S. T. Chemical, Kao Corp., Kobayashi Pharmaceutical, Ekomu,
Environment Purification Lab. and the like. The products are
commercially available in many different shapes such as liquid,
spray, fine powder and solid, and any of them are good to the
present invention as far as they can be used as a component of the
solvents thereof. For example, "Muko Kukan" (brand-name) sold by
Kobayashi Pharmaceutical has been found to be effective as a
deodorant. The deodorant, deodorizer, odor preventing agent,
aromatic and the like can be used singly or as a mixture of two
kinds or more. They are incorporated into the solvents in whatever
amount if it can achieve the object of the present invention but
the preferable amount is in a range of 0.5.about.10%.
[0027] Besides, pigments, colorants, insecticides, preservatives
and the like can be blended optionally.
[0028] According to the present invention, the oily deposits are
cleaned off the article to be cleaned with a release agent having a
water content of 10% by weight or less. The so described release
agent can be obtained by blending one solvent having a solubility
parameter of 8.0.about.9.8 and another having a solubility
parameter of 10.about.15. In blending, the solvents are either not
diluted with water or diluted with water or a mixed solution of
water and a surfactant at a ratio of 10 parts by weight or less to
100 parts by weight totaling the solvents. The water content is
preferably in a range of 0.about.6% by weight, more preferably
0.about.2% by weight. As the surfactant that can be used in
cleaning of the present invention, Ionet S-20. Sunmolin OT-70. New
Pole 50HB-55 and the like made by SANYO CHEMICAL INDUSTRIES can be
cited. Of them, Ionet-20 is preferable. Water/surfactant are mixed
at a ratio of 80 parts by weight/20 parts by weight .about.20 parts
by weight/80 parts by weight. Of the ratios, that of 50/50 is
particularly preferable.
[0029] Prepared from 25.about.80% by weight of (A) a terpene-based
hydrocarbon and/or hydrocarbon-based solvent having a solubility
parameter of 8.0.about.9.8 and 75.about.20% by weight of (B) an
alcohol including one or more hydroxyl groups and having a
solubility parameter of 10.about.15, the detergent is coated on the
article to be cleaned. After coating, a wax releasing device is
preferably caused to release wax while the detergent remains wet
without giving the time for its infiltration (within 3 minutes,
preferably within 1.about.2 minutes after coating). Thereafter, the
surface of the article to be cleaned is polished by using one kind
or more from among electric polisher, rolling cleaner, handy
cleaner, brush and the like as the wax releasing device. In this
way synthetic resin wax and the like are released in the shape of
powder. Of the cleaning methods, the one simple and convenient to
use is that synthetic resin wax and the like are released in the
shape of powder by using a polisher into which a floor brush is
fitted and powder is mopped up from the floor.
[0030] Since synthetic resin wax and the like are released in the
shape of powder, it is no more necessary to collect dirty water
resulting from cleaning. Whether or not synthetic resin wax is
released as a powder has an effect on the cleaning time. For the
sake of removal in the shape of powder, it is essential to use the
detergent comprising 25.about.80% by weight of (A) the
terpene-based hydrocarbon and/or hydrocarbon-based solvent having
the solubility parameter of 8.0.about.9.8 and 75.about.20% by
weight of (B) the alcohol including one or more hydroxyl groups and
having the solubility parameter of 10.about.15. Synthetic resin wax
is not released in the shape of powder if the terpene-based
hydrocarbon and/or hydrocarbon-based solvent having the solubility
parameter of 8.0.about.9.8 is used singly. Synthetic resin wax
cannot be released at all if the alcohol including one or more
hydroxyl groups and having the solubility parameter of 10.about.15
is used singly. The removal of synthetic resin wax and the like is
unsuitably insufficient with the combined use of one solvent having
a solubility parameter of less than 8.0 and another having a
solubility parameter of 10.about.15.
[0031] The present invention will be explained in detail below with
reference to examples and comparative examples.
EXAMPLES 1.about.10 AND COMPARATIVE EXAMPLES 1.about.5
[0032] Four-layer coating of commercially available synthetic resin
wax (Brand-name: Big Coat, made by Risdan Chemical) was provided on
the homogenous vinyl floor tiles in a size of 2 m.sup.2. Mixed
solvent compositions of limonene and alcohol as listed in Tables
1.about.3 were prepared from alcohols having the solubility
parameter in a range of 10.about.15 and limonene having the
solubility parameter of 8.5. In all Examples except for Example 3,
the mixed solvent compositions were coated on the above-mentioned
vinyl floor tiles without diluting them in water. In Example 3,
however, 10 parts by weight of a 1/1 mixed solution of water and
surfactant (Brand-name: Ionet S-20, made by SANYO CHEMICAL
INDUSTRIE; a nonionic surfactant) were incorporated into 100 parts
by weight of said mixed solvent composition and the resultant
mixture was coated on said vinyl floor tiles. In Example 9,
limonene used in Example 1 was singly coated on the floor, followed
by coating of ethanol. In Example 10, the test was likewise
conducted by using xylene in place of limonene in Example 1.
[0033] As Comparative Examples, a commercially available release
agent for use in floor (Brand-name: Bomber, made by Mukojima
Sansho; alkaline solvent for releasing chemical floor material) and
a mixed composition of limonene and ethanol (at a ratio of 33/67)
were respectively diluted 5-fold in water and coated. The other
Comparative Examples used a single limonene, a single ethanol and a
mixed solvent wherein octane having a solubility parameter of 7.6
was blended in place of limonene in Example 1, coating them without
diluting them in water. In the next place, a floor brush (No. 73)
made by Sumitomo 3M was fitted into a polisher made by Musashi
Electric Appliances, and said vinyl floor tiles were polished with
the use of so obtained device, to release the coats of synthetic
resin wax therefrom. In Examples, the released substances in the
shape of powder were dispersing over the floor and were mopped up
after polishing, followed by recoating of synthetic resin wax. In
the case of Comparative Example 1, dirty water was collected by a
wet cleaner after polishing and furthermore moisture was wiped off
from the floor with a mop lest the detergent content of the
cleaning-releasing formulation should remain lingering on the
floor. The floor was dried and thereafter synthetic resin wax was
recoated. In the case of Comparative Example 2 wherein there was
practically no dirty water, the released substances in the shape of
powder were mopped up from the floor after polishing, and synthetic
resin wax was recoated after one wipe of moisture.
[0034] The work properties were compared between Examples and
Comparative Examples, by evaluating the coating time, infiltration
properties of detergents (how long they were left to stand for
after polishing), polisher use time, necessity of dirty water
collection, necessity of moisture wipe and total operating time.
The results of evaluation are shown in Tables 1.about.3.

[0037] Examples 1.about.10 describes the cleaning methods of the
present invention. The methods comprise using the detergents
prepared from 25.about.80% by weight of (A) the terpene-based
hydrocarbon and/or hydrocarbon-based solvent having the solubility
parameter of 8.0.about.9.8 and 75.about.20% by weight of (B) the
alcohol including one or more hydroxyl groups and having the
solubility parameter of 10.about.15. Unlike those using
commercially available cleaning-releasing agents, methods of the
present invention don't need to collect dirty water, having good
infiltration properties. They also are excellent in workability of
moisture wiping, capable of finishing with all the operations in a
shorter span of time.
[0038] As compared with those of JP-A-2004-035651 by means of
dilution in water (Comparative Example 2), the methods of the
present invention have been found to be efficient in ending
infiltration soon after coating, saving the total operating time by
more than 30%.
[0039] It has been demonstrated in Comparative Examples 3 and 4
that the singly used solvents have a poor cleaning effect and that
excellent results can be obtained only with the combination of two
solvents disclosed in the present invention.
[0040] The cleaning methods of the present invention do not need to
collect dirty water and are good in infiltration properties,
excellent in workability of moisture wiping and capable of saving
the total operating time. Therefore, they will be very useful as a
method for cleaning the chemical tile-paved or stone-built floors
of coated synthetic resin wax and the like in convenience stores,
supermarkets, office buildings and the like.
[0041] The cleaning methods of the present invention can be used to
clean the many different articles to be cleaned by stripping off
deposited synthetic resin wax and the like in the same way as it is
done in the building floors.
