Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning composition for use in dry cleaning clothing, the purpose of which is to dry clean clothing, regardless of whether the clothing is made of natural or synthetic fibers. To provide a detergent composition for dry cleaning which can impart sufficient antistatic properties and flexibility to washed clothing and has re-staining prevention power.

In recent years, with the aim of simplifying and increasing the efficiency of dry cleaning operations, progress has been made in the development of detergent compositions for dry cleaning that can impart antistatic properties and flexibility to items to be washed at the same time as cleaning. This type of composition known so far has a quaternary ammonium salt type cationic surfactant as the main ingredient, and a nonionic surfactant such as polyoxyethylene alkyl phenyl ether or fatty acid jetanolamide is blended with this. (Japanese Patent Application Laid-open No. 50-76108 and 50-76108)
2-94306), or a combination of the above main ingredients with an amphoteric surfactant (Japanese Patent Laid-Open No. 54-139)
In addition to these, compositions based on salts of amines or diamines and organic acids are known. However, the conventional dry cleaning detergent compositions introduced above can all provide excellent antistatic properties to clothing when the material to be washed is synthetic fibers, but they cannot be applied to natural fibers such as wool. There was a concern that sufficient antistatic properties could not be imparted to these materials.

Furthermore, since dry cleaning uses a non-aqueous solvent as the cleaning medium, the cleaning medium is frequently used repeatedly, and therefore a considerable amount of dirt accumulates in the cleaning medium used in dry cleaning. Therefore, in a detergent composition for dry cleaning, it is important to have anti-static properties and so-called anti-recontamination ability, which prevents dirt once removed from the items to be washed from adhering to the items to be washed again. This is an important requirement, along with the ability to provide flexibility. However, conventional cleaning compositions
Both those based on grade salts and those based on amine or diamine salts have the disadvantage that they do not necessarily have sufficient re-staining prevention power on synthetic fibers.

The present inventors have conducted repeated research aimed at developing a detergent composition for dry cleaning that does not have the drawbacks mentioned above, and have found that by combining a specific amine salt and a specific polyhydric alcohol, Regardless of whether the material to be washed is natural fiber or synthetic fiber, it can impart excellent antistatic properties and flexibility to the material to be washed, and it also has excellent detergency and, therefore, recontamination prevention ability. It has been found that a cleaning composition can be obtained.

On the other hand, the dry cleaning detergent composition according to the present invention comprises a component (
A), I-lyeethylene glycol with an average loading of 2 to 1O, and polyzolopylene glycol and a carbon number of 2 to 1O.
It is characterized by containing a component (B) selected from the group consisting of polyhydric alcohols.

In the present invention, component (A) is represented by the following general formula (I)
The amine salt shown is a typical example.

[In the formula, RI is an alkyl group or an alkenyl group having 8 to 22 carbon atoms, R7 and R3 are hydrogen, an alkyl group having 1 to 22 carbon atoms, and an alkenyl group, and ~20; They may be the same or different, and X is a residue of an organic or inorganic acid. ] Among the amine salts represented by general formula (I), R8
is an alkyl group or alkenyl group having 12 to 18 carbon atoms, one or both of R2 and t-t3 1 to 10), and X is phosphoric acid, sulfuric acid, an aromatic sulfonic acid having 6 to 9 carbon atoms, or Amine salts, which are residues of carzenic acid having 2 to 18 carbon atoms, are preferred in that they can impart particularly excellent antistatic properties to the items to be washed.

Next, specific examples of all compounds that can be used as component (A) include lauryl jetanolamine, stearylamine ethylene oxide adduct (9=4), dilaurylamine ethylene oxide adduct (+)=2), Ethylene oxide adduct of oleylamine (lower = 10), ethylene oxide adduct of coconut alkylamine (p-6)
, propylene oxide adduct of coconut alkylamine, stearylamine, dilaurylamine (V-=2)
, propylene oxide adduct of oleylamine (p=8
), each amine such as propylene oxide/ethylene oxide adduct of coconut alkylamine, and phosphorus R1m+'1
R1d Salts of hexaacid such as dinzenesulfonic acid, para-toluenesulfonic acid, and sodium citrate can be mentioned.

Incidentally, component (A) is generally blended into the cleaning composition in the form of a salt, but since the above-mentioned amine and salt easily form a salt in the cleaning composition, when preparing the cleaning composition, may be blended in the form of amine and acid.

As mentioned above, the component (B) has an average degree of polymerization of 2 to 10.
Nobori ethylene glycol, polypropylene glycol, and polyhydric alcohols having 2 to 1 carbon atoms are used, but polyhydric alcohols having 2 to 10 carbon atoms include ethylene glycol, propylene glycol (1,2-zolonozone diol), 1.3-propanediol, 1,2-butanediol, 1,3-butanediol, 2.3-butanediol, 1,4-butanediol, 1,5-bentanediol, 2,4-bentanediol, 2 , 5-hexanediol, 2-methyl-2,4-bentanediol, 3-methyl-1,5-bentanediol, 3-methyl-2,4-bentanediol, 2-ethyl-1,3-hexanediol, Includes glycerin and the like. Preferred examples of component (B) of the present invention include polyethylene glycol with an average degree of polymerization of 2 to 10. ? Examples include polypropylene glycol ethylene glycol, propylene glycol, hexanediol, and glycerin.

Generally, in detergent compositions for dry cleaning, the amount of active ingredients in the composition does not matter much. This is because detergent compositions for dry cleaning generally contain a dry cleaning solvent as a dispersant for the active ingredients, but in actual dry cleaning operations, such detergent compositions are dispersed in a cleaning medium (dry cleaning solvent). This is because the amount of the active ingredient in the cleaning composition can be arbitrarily selected, provided that the concentration of the active ingredient in the medium can be maintained at a predetermined value. In the dry cleaning detergent composition of the present invention, the component (A)
and (B) are included in the composition,
The relative proportions of both components contained in the composition are j(i.

In order to ensure that the intended purpose of the present invention is achieved, the weight ratio of component (A) to component (B)' should be between 1071 and 1071.
1 (maintained in the range of 115).

If the weight ratio of component (A) and component (B) can be maintained within the above range, the composition of the present invention can be used as a dry cleaning bath agent as a dispersion medium for both of the above components, similar to general dry cleaning detergent compositions. In this case, the dry cleaning solvent can be a nandene-based or paraffin-based petroleum solvent, or a halogenated hydrocarbon solvent such as tetrachloroethylene, trichloroethylene, trichloroethane, or trichlorotrifluoroethane. Further, the composition of the present invention may contain about 3 to 10% by weight of a fatty acid alkanolamide for the purpose of further enhancing the antistatic effect and softening effect and increasing the water-holding capacity. is a fatty acid amide having 10 to 20 carbon atoms, such as coconut fatty acid jetanolamide, lauric acid jetanolamide, stearin diethanolamide, oleic acid jetanolamide, coconut fatty acid monoethanolamide, etc.” (7) Ethylene oxide adduct (i=1-1

In addition, the composition of the present invention can also contain ingredients commonly used in dry cleaning detergent compositions, such as biphenyl-based, coumarin-based or stilbene-based fluorescent agents, metal corrosion inhibitors, In addition to fragrances, lower alcohols such as methyl alcohol and 2-zolopanol, ethers such as ethylene glycol monobutyl ether, butyl isozorobyl ether, and diethylene glycol monodityl ether, hydrocarbons such as n-hexane, and methyl isocarbons. Ketones such as dithyl ketone A:A
Liquid or water can also be blended as a solubilizer, liquid stability improver, or lance solvent. However, even when the dry cleaning detergent composition of the present invention contains any optional components, the (Q degree) of component (A) is 5 to 8.
It is convenient for handling to maintain the concentration of component ('') in the range of 1 to 20% by weight, preferably 3 to 15% by weight. be.
