2. Description of the Related Art Conventionally, a cleansing agent has been used for the purpose of removing makeup cosmetics, and a cleansing agent has been used to remove skin waste, adhered dirt, residual oil after cleansing, etc. It is used. Cleansing agents mainly use the dissolving action of makeup cosmetics with surfactants and oils, and the dosage forms are generally lotions, emulsions, creams and oils. It has been used according to usability. Also,
The face wash mainly utilizes the detergency of the surfactant, and as the surfactant, there are, for example, those containing sodium salts or potassium salts of higher fatty acids, N-acyl glutamate, etc. as main components. In general, creamy and lotion-like ones are generally used.

[0003]

However, as for the cleansing agent, although the lotion-like agent has a good feeling in use, in the case of hard makeup, the effect of removing the cosmetic agent may not be obtained satisfactorily. . In addition, although milky liquid, creamy, and oily substances can perform the function of removing makeup cosmetics,
Since an oil agent is blended, it may lack a refreshing feeling after use, and in some cases it may be necessary to wash the face thereafter. On the other hand, in the face wash, the face wash containing sodium or potassium salt of higher fatty acid, N-acylglutamate, etc. as a main component cleans and removes skin wastes, adhering dirt, and residual oil after cleansing. Although the function is excellent, especially in the case of hard makeup, the removal of the cosmetics only with the face wash was not sufficient. Therefore, there has been a demand for a makeup remover that is excellent in removing cosmetics even in the case of hard makeup and has a refreshing feel without leaving oil and the like on the skin after use.

[0004]

In view of such circumstances, the inventors of the present invention have conducted extensive studies to solve and overcome the above-mentioned drawbacks, and as a result, specific nonionic surfactants and anionic surfactants have been obtained. And a combination of amphoteric surfactants in specific amounts, and by using a water-soluble polymer compound having a thickening effect and water to impart an appropriate viscosity to the system, the effect of removing makeup cosmetics is excellent, and It was found that a make-up remover that works well as a cleansing agent having good detergency and foamability at the time of washing off with a skin-friendly makeup remover having a refreshing feeling after washing is obtained, and completes the present invention based on this finding. It was

Regarding the polyoxyethylene chain length, in the general formula (1), when x = 0 and y = 1, fatty acid monoethanolamide is represented, and when x = y = 1, fatty acid diethanolamide is represented. When x = 0 and y ≧ 2, it represents a polyoxyethylene fatty acid monoethanolamide, and when x ≧ 2 and y ≧ 1, it represents a polyoxyethylene fatty acid diethanolamide. In the present invention, 2 ≦ x + y ≦ 20 is preferable, and further, x ≧ 1 and y ≧ 1 and 2 ≦ x + y ≦ 15, or x ≧ 0 and y ≧ 5 and 5 ≦ x + y ≦ 15. ,
It is more preferable for obtaining a refreshing feeling after use.

In the present invention, these fatty acid amide type nonionic surfactants and / or polyoxyethylene fatty acid amide type nonionic surfactants may be used alone or in combination.
One or more species can be used, and the blending amount thereof is 0.
It is 5 to 7% by weight (hereinafter, simply indicated by%), and more preferably 1 to 5%. If it is less than 0.5%, the effect of removing make-up cosmetics cannot be sufficiently obtained, and if it exceeds 7%, the effect of the present invention cannot be further improved, and rather, it is satisfactory in terms of gentleness to the skin. No longer.

The higher fatty acid salt and / or N-long chain acylamino acid salt of the component (B) used in the present invention is a component necessary for providing good foaming property and good detergency. As such a higher fatty acid salt, a saturated or unsaturated fatty acid salt having 12 to 20 carbon atoms is preferable, but lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid,
Palm oil fatty acid and beef tallow fatty acid are more preferable. Also, N-
The long-chain acylamino acid salt has 12 to 1 carbon atoms in the acyl group.
8 is preferable. There is no particular limitation on these alkalis, and any alkali agent usually used in cosmetics can be used, but triethanolamine is particularly preferable. Among these components (B), coconut oil fatty acid triethanolamine, laurate triethanolamine, myristate triethanolamine, oleate triethanolamine, N-lauroylglutamate triethanolamine, N-myristoylglutamate triethanolamine. , N-coconut oil fatty acid acylglutamate triethanolamine is preferred.

One kind or two or more kinds of carboxymethoxyethyl-N-carboxymethylethylenediamine disodium can be used, and the compounding amount thereof is 0.3 to 7%, more preferably 0.5 to 5% in the whole composition. If it is less than 0.3%, the foaming property is insufficient, and the softness to the skin is not satisfactory. Further, if it exceeds 7%, the refreshing feeling after washing may be poor.

The water-soluble polymer of the component (D) and the water of the component (E) used in the present invention increase the viscosity of the system, and thus make up the makeup cosmetics of the components (A) to (C). This is to synergistically improve the removal effect and the good cleaning property and foaming property at the time of rinsing. That is, the viscosity of the system at 20 ° C. is 50% by using the water-soluble polymer compound.
Those adjusted to 100 to 100,000 cps are easily adapted to the makeup cosmetics and stains on the skin by the force of the fingers during the operation of removing the makeup cosmetics, and bubbles are easily formed by friction. Further, since the system is thickened by the water-soluble polymer, it is possible to prepare a transparent composition, and it is possible to obtain a transparent make-up cosmetic composition remover having a beautiful appearance.

As the water-soluble polymer as the component (D), carboxyvinyl polymer, xanthan gum, methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, sodium alginate, arge colloid, carrageenan, polyvinyl alcohol, polyvinylpyrrolidone, etc. are usually used in cosmetics. Although any water-soluble polymer can be used, carboxyvinyl polymer, methyl cellulose and xanthan gum are particularly preferable.

In the present invention, these water-soluble polymers can be used alone or in admixture of two or more, and the viscosity value at 20 ° C. required for the system of the present invention is 5000 to 100.
An amount is added to give 000 cps. Viscosity value is 500
If it is less than 0 cps, it is not sufficiently compatible with the makeup cosmetics and stains on the skin, and if it exceeds 100,000 cps, it is too hard and the usability as a product is not satisfactory.

In general, a cleansing agent or a makeup removing agent can have a removing effect by adding an oil component, but in the makeup removing agent of the present invention, the above-mentioned components (A) to (C) are added. As a result, a sufficient removal effect can be obtained, so that it is not particularly necessary to contain oil. By substantially not containing oils such as hydrocarbons, esters, oils and fats, and waxes, a make-up remover that gives a fresher feeling to the skin after use can be obtained.
