Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dry cleaning detergent composition.

One of the roles of detergents in dry cleaning is to solubilize water, which is generally referred to as water-holding capacity. Its purpose is to remove water-soluble stains that adhere to clothing by the action of water solubilized by the action of detergents in Dreich + J-Jung's organic solvents such as 1,1.1-) dichloroethane and perchlorethylene. A filter that protects clothing from damage that is susceptible to shrinkage, loss of shape, and color loss due to water, and solubilizes water carried by clothing during bathing. The aim is to suppress the pressure increase. Detergents used for this purpose are naturally required to have a high water-holding ability to solubilize a large amount of water in the dry cleaning organic solvent.

As surfactants for detergent components used for this purpose, anionic surfactants include petroleum sulfonates, dialkyl sulfosuccinate salts, alkylbenzene sulfonate salts, and di- or monoalkyl phosphate salts.
Nonionic surfactants include polyoxyethylene nonylphenyl ether, fatty acid rubitan ester, polyoxyethylene alkyl ether, and fatty acid alkanolamide. All of these have advantages and disadvantages, and although they have been used in various combinations, a fully satisfactory product has not yet been obtained.

The object of the present invention is to obtain a detergent composition having a high water-holding capacity.

This objective is achieved by the following specific combination of compositions.

That is, it contains surfactants represented by the following general formulas A, B, and C as active ingredients, and surfactants A, B, and C
When the total amount of is 100 parts by weight, surfactant A is 5 parts by weight.
50 parts by weight of surfactant B, 5 to 50 parts by weight of surfactant C, and 5 to 85 parts by weight of surfactant C.

A Nidialkyl sulfosuccinate salt R100C-CH, (wherein R0 and R3 have 6 to 6 carbon atoms
B: Secondary alkanesulfonate R3-C-R, (in the formula R
3 and R4 are alkyl groups whose total number is 5OsX and the number of carbon atoms is 8
~18, M represents an alkali metal or alkanolamine t) C: T[11ylkylbenzenesulfonate Rs (=
Stain 0s Mm (In the formula, 4 represents a linear alkyl group having a carbon number of 1θ to 14, and the dove represents an alkali metal or an alkanolamine.) Component (3) used in the present invention, that is, a dialkyl sulfosoxy group represented by the general formula A The carbon number of the alkyl group of the nate salt is 6 to 9, and 2-etherhexyl group and n-octyl group are preferable.

Such long-chain alkyl groups are undesirable because the boiling point of a considerable amount of coexisting higher alcohols is high, and they remain on clothing even after washing, leaving a characteristic odor. The number of carbon atoms in the alkyl group is 6
Below that, the hydrophilicity is too strong and the aqueous nature of the aspiration decreases. Further, the soion M1 is preferably an alkaline alkanolamine, and the alkali metal is Na. Alkanolamine is a mono-, di-, or trialkanolamine in which the alkanol group has 2 to 3 carbon atoms.
Examples of these include monoethanolamine, jetanolamine, triethanolamine, monoimpropaturamine, diiso-10panolamine, triimpropaturamine, and the like.

Among these dialkyl sulfosuccinate salts, particularly preferred ones are as follows.

(B) Sodium di-2-ethylhexylsulfosuccinate (B) Sodium moro-octylsulfosuccinate (C) Potassium di-2-ethylhexylsulfosuccinate) Potassium di-n-octylsulfosuccinate component (B)
) That is, the total number of carbon atoms in the alkyl group of the secondary alkansodium sulfonate represented by the general formula B is 8 to 18, and the counter ion is the same as in the dialkyl succinate.

The number of carbon atoms in the alkyl group of component (C), that is, the linear alkylbenzene sulfonate represented by the above general formula C is 10.
~14, and the counter ion M is preferably an alkali metal or an alkanolamine, the alkali metal is Na, and the alkanolamine is an alkanol group having 2 to 3 carbon atoms.
mono-, di- or trialkanolamines. Specific examples include monoethanolamine, -jetanolamine, triethanolamine, monoisopropanolamine, diiso7'Ohanolamine, tripropropanolamine, and the like.

Particularly preferred examples of these linear alkylbenzene sulfones are as follows.

(b) Linear dodecylbenzenesulfone sodium (
(b) Potassium linear dodecylbenzenesulfonate The use of these three components is essential in the dry cleaning detergent of the present invention. For example, each component alone or a combination of only two components is unsuitable because the water-holding capacity is not improved. Furthermore, in order to achieve the intended purpose of the present invention, the blending ratio of each component is extremely limited, and the blending ratio of these three components is 4 parts by weight when the total amount of the three components is 100 parts ) is 5-50 weight 1, component (B) is 5-5
0 parts by weight, component (C) should be 5 to 85 parts by weight. As is clear from the results in Examples described below, if the ratio of the three components is outside this range, a detergent with high water-holding ability cannot be obtained.

The detergent composition of the present invention can further contain various known components in addition to the above-mentioned essential components. Examples include anionic surfactants such as mono- or dialkyl phosphate esters, nonionic surfactants such as polyoxyethylene alkyl ethers, polyoxyethylene alkylphenyl ethers, alkanolamides of higher fatty acids, and fatty acid sorbitan esters. Other auxiliary ingredients include lower alcohols, lower alkyl glycol ethers, such as ethanol, ingropanol, n-7' Lovano A-, eteluselonlube, buteluselonlube, etc., fluorescent whitening agents,
Examples include water, organic solvents for dry cleaning, etc., and these auxiliary components can be blended in appropriate amounts as long as they do not particularly impede the effects of the composition of the present invention.

Next, the present invention will be explained using examples.

Example 1 Dry cleaning detergent compositions with various formulations were prepared,
The water-holding ability and detergency of the prepared detergent composition were evaluated as FF@j by the following evaluation method. The results are shown in Table 1 and Table 2. Note that TEA in the table represents triethanolamine as a counter ion.

(Water-holding capacity test) Take 1.1.1-trichloroethane (trade name: Taclin, manufactured by Asahi Kasei Corporation) at 5 o IR in a 100N test tube, add the specified amount of detergent composition, stir well, and use a microsyringe to Add water little by little, shake, and repeat until the liquid becomes cloudy while observing how cloudy it is.The amount of water added just before cloudiness occurs is defined as the amount of water held.

(2) Cleaning power test - polyester cloth (cut into 10cm x 10 pieces)
Approximately 5i% of NaCl was attached to the weight of the fibers, and half (5crrLX5crIL) was added to the NaCl before washing.
The remaining half molecule Scrub-0-
The detergent composition concentration is 1% by volume using a meter washer.
, 1,1,1-trichloroethane containing 0.1% by weight of water at 25°C.

It was washed for 20 minutes without rinsing. Next, in order to calculate the amount of NaCl attached before and after washing, the NaCl attached to the polyester cloth before and after washing was extracted with water, and the amount of NaCl in the extracted water was determined by Hg (NOJt standard titration method).
The detergency was calculated using the following formula.
