[evaluation]
(Foam quality, rinse and moisturizing effect)
Evaluation of foaming quality, rinsing property and moisturizing effect of each of the compositions according to Examples 1 to 5 and Comparative Examples 1 to 6 was carried out by an expert panel based on the internal evaluation standard. A good moisturizing effect brings a good feel to the skin after rinsing, such as skin hypoallergenicity and moisturizing sensation. These characteristics were evaluated according to the evaluation criteria shown below.
Good: Acceptable or Good Insufficient: Not very good or unacceptable

(Stability)
The viscosities of the compositions according to Examples 1-5 and Comparative Examples 1-6 were measured by a proRheo reometer R180 (proRheo GmbH) using a 25 mL cup with Mobile 4 at 200 rpm and 25 ° C. The viscosity value after mixing the composition for 10 minutes was read. Measurements were performed immediately after the composition was prepared and after storage at 4 ° C or 45 ° C for 2 months. Stability was evaluated according to the evaluation criteria shown below.
Good: The decrease in viscosity after storage at 4 ° C and 45 ° C for 2 months was within 30% of the initial viscosity value.
Insufficient: The decrease in viscosity after storage at 4 ° C and 45 ° C for 2 months exceeded 30% of the initial viscosity value.

The evaluation results are summarized in Table 3 below.

As can be seen from Table 3 (Table 3), the compositions according to each of Examples 1 to 5 containing the specific combination of the components (a) to (d) of the present invention have good foaming quality, rinsing property and moisturizing property. It showed good stability while maintaining its effect.

On the other hand, the composition according to Comparative Example 1 lacking an amphipathic fatty substance and an associative copolymer of (meth) acrylic acid and a (C ₁ to C ₆ ) alkyl ester of (meth) acrylic acid was inferior in stability. showed that. The composition according to Comparative Example 2 lacking the copolymer of (meth) acrylic acid and the (C ₁ to C ₆ ) alkyl esters of (meth) acrylic acid also showed inferior stability. Similarly, the composition according to Comparative Example 3 lacking amphipathic fatty substances showed inferior stability. Contains lauric acid and glyceryl stearate as additional surfactants, but lacks amphipathic fatty substances and copolymers associated with (C ₁ -C ₆ ) alkyl esters of (meth) acrylic acid and (meth) acrylic acid. The composition according to Comparative Example 4 showed insufficient foaming quality. Comparative example of containing lauric acid and glyceryl stearate as additional surfactants, but lacking an associative copolymer of (meth) acrylic acid and (C ₁ to C ₆ ) alkyl esters of (meth) acrylic acid. The composition according to 5 showed poor foaming quality. Comparative Example 6 containing PEG-120 methylglucose dioleate as an additional thickener, but lacking an associative copolymer of (meth) acrylic acid and (C ₁ to C ₆ ) alkyl esters of (meth) acrylic acid. The composition according to the above showed insufficient rinsing property.

Therefore, the composition according to the present invention exhibits good foaming quality, rinsing property, a skin care effect that gives a moisturizing sensation to the skin after rinsing, and good stability, so that it is very suitable as a composition for cleansing keratin substances. It can be concluded that it can be preferable.
