SOLUTION: This skin-washing agent contains a polyoxyalkylenedicarboxylic acid ester of the general formula (1) (wherein, R1 and R2 are each H, or a 1-4C alkyl or branched alkyl; (m), (n), X and Y are each an integer of 0-5, and they can not be zero at the same time; and R3 is a 0-10C branched or straight alkylene) and a surfactant.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a skin cleanser. More specifically, the present invention relates to a skin cleanser having a high makeup removing effect and excellent foaming.

[0002]

2. Description of the Related Art Conventionally, cleansing foams, facial cleansing gels and cleansing oils containing an oil component containing a surfactant as a main component have been used for the purpose of removing makeup cosmetics adhering to the skin.

[0003]

However, cleansing foams and facial cleansing gels remove the film such as silicone resin of make-up cosmetics by the detergency of a surfactant, and have the advantage that they are well foamed and can be easily removed. On the other hand, the effect of removing makeup is not enough.

[0004] In addition, the cleansing oil has a problem that it dissolves the film of makeup cosmetics well and has an excellent cleaning effect, but it does not foam and does not give a refreshing finish. Since the silicone resin contained in makeup cosmetics is soluble in oil, the concept is that it would be conceivable that if oil was incorporated into a surfactant-based formulation, the purpose would be fulfilled, but ordinary oil would dissolve in water. Instead, since a surfactant is used to solubilize or emulsify this oil, this concept does not foam and gives a refreshing skin feeling.

The inventors of the present invention have conducted intensive studies in view of the above-mentioned problems. As a result, a skin cleanser containing a specific polyoxyalkylene dicarboxylic acid ester and a surfactant has a high makeup removing effect, is excellent in foaming, and They found that they could be washed off completely and completed the present invention.

[0006] It is an object of the present invention to provide a skin cleanser which has a high makeup removing effect, is excellent in foaming, and can be washed away.

[0007]

That is, the present invention provides a skin cleanser comprising a polyoxyalkylenedicarboxylic acid ester represented by the following general formula (1) and a surfactant. It is.

Embedded image (1) (wherein, R 1 and R 2 are hydrogen or an alkyl or branched alkyl group having 1 to 4 carbon atoms, and m, n, X and Y are 0 to 0)
Integers of 5 are not simultaneously 0. R3 has 0 to 1 carbon atoms
A branched or linear alkylene group of 0)

[0008] The present invention also provides the above-mentioned skin cleanser, wherein the polyoxyalkylene dicarboxylic acid ester is diethoxyethyl succinate.

Furthermore, the present invention provides the above-mentioned skin cleanser, wherein the skin cleanser is a makeup remover.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail.

The polyoxyethylene dicarboxylic acid ester of the above formula (1) used in the present invention is a known substance, but is a novel compounding ingredient as a skin cleansing ingredient.

In the above general formula (1), R1 and R2 each represent an alkyl or branched alkyl group having 1 to 4 carbon atoms. If the number of carbon atoms is 5 or more, the skin cleansing agent does not foam due to lack of hydrophilicity. m, n, X and Y each represent an integer of 0 to 5, preferably an integer of 1 to 2, and if the sum of m, n, X and Y is 0, the skin cleansing agent is not hydrophilic. Foaming does not occur, and if it exceeds 15, the solubility of the makeup cosmetic becomes poor, and the makeup removing effect becomes small. R3 represents a branched or straight-chain alkylene group having 0 to 10 carbon atoms. If the number of carbon atoms is 11 or more, R3 lacks hydrophilicity and the skin cleanser does not foam.

When the polyoxyalkylene dicarboxylic acid ester of the general formula (1) is diethoxyethyl succinate, a skin cleansing agent having a particularly high makeup removing effect and excellent foaming can be obtained.

The amount of the polyoxyalkylene dicarboxylic acid ester is not particularly limited, but is preferably 0.1 to 10% by weight, more preferably 1 to 10% by weight in the skin cleanser. If the amount is less than 0.1% by weight, the effect of the present invention is small, and if the amount exceeds 10% by weight, water is separated and the effect of the present invention cannot be exhibited.

The surfactant used in the present invention is not particularly limited as long as it is a surfactant generally used in skin cleansing agents. For example, potassium laurate, sodium laurate, triethanolammonium laurate, myristine Fatty acid soaps such as potassium citrate, sodium myristate, triethanol ammonium myristate,

The amount of the surfactant is not particularly limited and is appropriately determined depending on the product, but is preferably 10 to 50% by weight based on the total amount of the skin cleanser.

The skin cleanser of the present invention is intended to be applied to the outer skin such as cosmetics, medicines, quasi-drugs and the like, and is intended for skin cleansing. In particular, it is preferably used as a makeup remover for removing makeup cosmetics such as makeup removers. The dosage form can take a wide range of forms such as an aqueous solution type, an emulsion type and a gel type.

Next, preferred embodiments of the present invention will be described. Note that the present invention is not limited to these. Unless otherwise specified, the compounding amount is shown in% by weight.

"Examples 1-3, Comparative Example 1" Cleansing gels of Examples and Comparative Examples shown in "Table 2" and "Table 3" were produced and subjected to a lipstick detergency test and a bubble test. Polyoxyalkylene dicarboxylic acid ester, diethoxyethyl succinate, diethyl carbitol sebacate,
Ethyl ethoxyethyl adipate was used.

<Lipstick Detergency Test> Lipstick having the formulation shown in Table 1 below was uniformly applied to artificial leather and dried for 10 minutes.

[Table 1] Lipstick prescription

Each sample of Examples 1-3 and Comparative Example 1 0.1
Attach the cotton impregnated with g to the reciprocating arm 5
Five reciprocations were performed on artificial leather coated with lipstick with a weight of 0 g. Next, the amount of the lipstick on the artificial leather was measured as the color difference from the uncoated portion using a color difference meter, and the amount of the lipstick that fell off relative to the amount of the lipstick before rubbing with the sample was determined as a percentage and the detergency (%). And Table 2 shows the cleansing gel (test sample) formulations of Examples 1 to 3 and Comparative Example 1. The results are shown in Table 2 together.

[0023]

[Table 2] "Cleansing gel and lipstick detergency of Examples 1-3 and Comparative Example 1"

As is clear from Table 2, when the polyoxyalkylene dicarboxylic acid ester of the present invention, particularly diethoxyethyl succinate, was added to the formulation of Comparative Example 1, the lipstick detergency increased.

A cleansing gel was prepared according to each of the formulas shown in "Foaming test" and "Table 3". Next, 1% of each formulation was dissolved in an aqueous 70 ppm calcium chloride solution, and 400 mL of each solution was stirred with a mixer to obtain 6%.
The amount of foam after 0 seconds was measured and defined as the foaming power. The prescription and the results are shown in Table 3 together.

[0026]

[Table 3] "Cleansing gel and foaming power of Examples 1-3 and Comparative Examples 1-3"

As apparent from Table 3, the polyoxyalkylenedicarboxylic acid ester did not decrease the foaming power of the surfactant as compared with other oils such as liquid paraffin and cetyl isononanoate. . It was also found that diethoxyethyl succinate did not inhibit foaming the most.

As is apparent from the above, it was found that the skin cleanser prepared by combining the polyoxyalkylene dicarboxylic acid ester and the surfactant had a high makeup removing effect and was excellent in foaming. Hereinafter, other examples of the present invention will be described.
