Description

  The present invention relates to a transparent cleansing cosmetic. More specifically, even when the water resistance is good and the hands and face are wet with water, an excellent cleansing effect is exhibited, and the water washability is very good. The present invention relates to a transparent cleansing cosmetic excellent in sensory characteristics.

Cleansing cosmetics for washing makeup cosmetics such as foundations, eye makeup, and lipsticks are completely formulated with creams, emulsions, oils, oily gels, and other oils. There are various types, such as lotion-like or water-based gel-like, with little or no blending. For example, as a type in which an oil agent is blended, a non-aqueous oil-based cleansing cosmetic composition having non-ionic surfactant and liquid oil as essential components shown in Patent Document 1, a specific non-ion shown in Patent Document 2 Oily cleansing cosmetics containing a surfactant, water and liquid oil have been proposed. These oily cleansing cosmetics utilize the dissolving action of the makeup cosmetics by the oil, have good compatibility with the makeup cosmetics and have a high cleansing effect. However, these oil-type cleansing cosmetics have a problem that, when their hands and face are wet with water, they are not very familiar with makeup cosmetics and the desired cleansing effect cannot be exhibited. For this reason, it has become essential to blend in with makeup cosmetics while the hands and face are always dry, and its usage has been limited. Furthermore, the washability at the time of rinsing is poor, the oily feeling is generated on the skin after use, the refreshing feeling after use is lacking, and then the facial cleanser mainly composed of higher fatty acid sodium salt or potassium salt and N-acylglutamic acid. I had to wash my face. In addition, when used for makeup cosmetics with good makeup that are often used recently, the oily feeling after washing with water has become stronger, and there has been a sensory problem such as stickiness of the skin. Further, a type in which no oil agent is blended or a trace amount is blended has a problem that the cleansing power is weak although there is little oiliness after cleansing. As a method for solving the above-described problems, a gel-like detergent containing polyoxyethylene fatty acid ester, polyhydric alcohol or glycol ether, and a water-soluble polymer as shown in Patent Document 3 has been reported. However, this product was also very unfamiliar with makeup cosmetics and was unable to exhibit the intended cleansing effect. From the above, cleansing cosmetics that have overcome the above problems, that is, good water resistance, even when the hands and face are wet with water, exhibit an excellent cleansing effect, and also have very good water washability It has been desired to develop a transparent cleansing cosmetic material having excellent sensory characteristics.
