Description

  The present invention relates to an aqueous skin cleansing cosmetic. More specifically, the present invention relates to an aqueous skin cleansing cosmetic that is excellent in makeup removal effect, and further exhibits a cleansing effect with good foaming and foam quality.

  Conventionally, aqueous skin cleansing cosmetics, so-called cleansing wash cosmetics, having both a face washing function and a makeup removing function (cleansing function) are known. Cleansing wash cosmetics are required to have an excellent makeup removing effect, good foaming and excellent facial cleansing effect.

  As the cleansing wash cosmetics, for example, fatty acid soap skin cleansing cosmetics are known (see, for example, Patent Documents 1 and 2). However, these fatty acid soap-based skin cleansing cosmetics have problems such as strong irritation when in contact with eyes, excessive degreasing, and difficulty in obtaining a moist feeling (moisturizing feeling) after use.

  On the other hand, in fields other than cleansing wash cosmetics, for example, N-acylamino acid type anionic surfactants and amphoteric surfactants as skin cleansing cosmetics with excellent mildness to the skin and good foam quality A liquid detergent composition containing polyethylene glycol is known (see Patent Document 3). Further, a cleansing agent containing a hydroxyalkyl ether carboxylate and an oily component as a facial cleanser having high foaming power and excellent moist feeling after use is known (see Patent Document 4). However, neither the liquid detergent composition nor the cleaning material has a sufficient makeup removing function and is insufficient as a cleansing wash cosmetic.

  Accordingly, there is a need for a skin cleansing cosmetic that has both a makeup removing effect and a facial cleansing effect, a low eye irritation, and a moist feeling after use.

(7) Eye irritation (eye irritation evaluation method using rabbit corneal cells (SIRC))
SIRC cytotoxicity tests using rabbit corneal cells (SIRC) were performed using each skin cleansing cosmetic as a test sample, and eye irritation was determined.
Test samples diluted in several stages were exposed to confluent SIRC for 5 minutes. After completion of the exposure, the plate was washed 10 times with PBS (−), added with MTT solution, and reacted for 4 hours.
A solvent in which the test sample was diluted was used as a negative control, and triethanolamine was used as a positive control.
After the reaction, the absorbance (580 nm) of the extract was measured, and the cell viability was calculated with the negative control value set to 100.
The concentration at which the cell viability was 50% (IC ₅₀ value) was calculated, and based on the IC ₅₀ value of the positive control, no stimulation (◯) when above the reference, and stimulation (×) when below the reference (×) ).
