Description

  The present invention relates to a skin cleanser composition such as a facial cleanser, body shampoo, hand soap, etc. More specifically, it has a good elongation during use, is excellent in foaming and foam quality, and is effective for makeup cosmetics and sunscreen agents. The present invention relates to a cleansing composition for skin that does not require double cleansing and can be removed cleanly and can be washed cleanly without being moistened after rinsing.

  Makeup cosmetics such as mascara, lipstick and foundation have the effect of making the skin beautiful and protecting the skin from external stimuli, and are indispensable for women's lives. On the other hand, sunscreen agents for preventing sunburn have been used by both men and women due to increased awareness of skin care. However, since these makeup cosmetics and sunscreen agents contain a large amount of oily components and inorganic pigments, they block the pores of the skin and prevent metabolism, and the cosmetics and sunscreen agents themselves are gradually oxidized. It may be irritating and long-term use may cause skin problems. For this reason, it is necessary to remove these cosmetics and sunscreen agents once a day using a cleansing material.

  Many makeup cosmetics and sunscreen preparations are designed to maintain oleophilic properties after application to the skin to prevent them from running off due to sweat, etc. It is difficult to remove them sufficiently with ionic surfactants such as. Therefore, in the first stage, it is removed using a cleanser (makeup remover) that contains a lot of oily ingredients that are compatible with makeup cosmetics and sunscreen agents, and in the second stage, ionic surfactants such as soap (face wash) Cleans the skin by foaming a cleansing agent mainly composed of foam), and with the remaining oil from the makeup remover and sebum, mud, dust, and dirt on the skin, it gives a feeling of cleanliness or refreshment. It was.

  The reason why such two-stage cleaning, so-called double cleansing, is necessary is that the oily component-based cleaning agent does not sufficiently remove the oily component remaining on the skin even after rinsing with water after use. This is because a feeling of cleansing cannot be obtained, and the skin-cleaning cleanser that uses soap and other foaming foams only removes pigments and pigments covered with oily ingredients in makeup cosmetics and sunscreens. This is because it cannot be sufficiently removed from above. However, in recent years when quick and simple makeup is required, double cleansing is a time-consuming action, and there are cases in which a heavy burden on the skin is caused by two washings.

  On the other hand, sunscreen agents are increasingly used regardless of gender due to increased skin care consciousness, but because men currently have little practice of double cleansing, removal of oily components and the like is not possible. In some cases, it is sufficient and a refreshing feeling cannot be obtained.

  Therefore, it is strongly desired to develop a skin cleansing agent that does not require double cleansing, which has the effect of effectively removing makeup cosmetics and sunscreen agents with only one washing, and the effect of imparting a refreshing feeling after washing. It was.

  As such a cleaning material, for example, Patent Document 1 proposes a one-phase cleansing composition containing a nonionic surfactant, a compound having a hydroxyl group, and an oil component. Although it has good elongation at the time of use, it contains a lot of oily components, so it not only feels slimy after rinsing, but also it is difficult to rinse while foaming, and it was difficult to get a satisfaction of washing up freshly .

  Patent Document 2 proposes a foaming detergent composition containing 20% by mass or more of a fatty acid alkanolamide, an oily component and an anionic surfactant that does not require double cleansing. Further, Patent Document 3 proposes a foam cleansing agent that does not require double cleansing and is composed of a combination of 50 to 90% by mass of a liquid oily component, an anionic surfactant, and a nonionic surfactant. Since these contain 50% or more of a liquid oily component, the feeling of slimness after use remains and sometimes double cleansing is necessary. In addition, it has a moist feeling but cannot be washed cleanly.

  Patent Document 4 proposes a cleansing material combining polyglycerin and an alkyl glucoside type nonionic surfactant. This can be done by removing make-up cosmetics and then adding water to make it foam while whipping, but its foaming and foam quality are not sufficient, and it can give a moist feeling after rinsing. Not.

  Furthermore, although the cleaning materials of Patent Documents 1 to 4 all have some effects on makeup cosmetics, they contain a large amount of inorganic substances such as ultraviolet absorbers, titanium oxide, and zinc oxide, and the skin. The fact is that a sufficient effect is not obtained for the sunscreen agent with improved adhesion. Further, it was far from the refreshing feeling obtained by washing the bare skin with soap or the like.
