Description

  The present invention relates to a cleansing cosmetic.

  Conventionally, cleansing cosmetics for removing sebum stains and makeup cosmetics on the skin include oil-based cleansing cosmetics mainly composed of liquid oil, etc. Emulsified cleansing cosmetics made into an emulsion, and further aqueous cleansing cosmetics mainly composed of aqueous components and water-soluble polymers have been used. Among these, the water-based cleansing cosmetics have a characteristic of having a refreshing feeling during use due to the low content of oily components, while having a cleansing effect on sebum stains and oily makeup cosmetics. There was a problem that it was not enough.

  In order to improve these points, heat of hydration of inorganic salts, polyhydric alcohols, etc. is used to give a feeling of heat when used, open pores, soften the skin, adapt to dirt, and wash Attempts have been made to improve sex. Specifically, pack cosmetics (Patent Document 1) containing inorganic minerals and clay minerals as gelling agents, cleansing compositions (Patent Document 2) combining moisturizers, oils and water, polyhydric alcohols and washings Cosmetics combining nonionic surfactants such as polyglycerin fatty acid ester and higher fatty acid ethanolamide as ingredients (Patent Documents 3 and 4), polyoxyethylene fatty acid glycerin and polyhydric alcohol, nonionic surfactant, anionic Cleansing compositions such as cleansing cosmetics (Patent Documents 5 to 7) combined with a surfactant or the like have been proposed.

JP 62-30704 A JP 09-48706 A Japanese Patent Laid-Open No. 11-263719 JP 2002-284672 A JP 11-199438 A JP 11-199439 A JP 2002-284640 A

However, when utilizing the heat of hydration of inorganic salts, there may be inconveniences in terms of usability, such as the generation of a large amount of heat locally or the variation in heat generation depending on the type of inorganic salt. It was. In addition, when using the heat of hydration of polyhydric alcohol, it is excellent in warmth, but the cleansing effect is insufficient, the elongation at the time of skin application is heavy, the rinsing takes time, and it becomes sticky after use. There was a case. Furthermore, depending on the type and blending amount of the nonionic surfactant to be combined, not only the cleansing effect is insufficient, but also the stability may be hindered.
Accordingly, an object of the present invention is to provide a cleansing cosmetic which has both a sufficient warm feeling and a cleansing effect, is excellent in ease of massage, rinseability, feel after use, and is excellent in stability.

  As a result of intensive studies to achieve the above object, the present inventor has found that a polyhydric alcohol, two or more kinds of branched fatty acid polyoxyethylene glyceryl, a high HLB nonionic surfactant, and an anionic water solution By containing a functional polymer as an essential component and containing them in a specific amount range, it has both sufficient warmth and cleansing effect, excellent ease of massage, rinsability, and feel after use, and stability. Has found that an excellent cleansing cosmetic can be obtained, and has completed the present invention.
