NATURAL SURFACTANT FOR COSMETICS AND COSMETIC COMPOSITION COMPRISING THE SAME <br> <br> <br> Patents - stay tuned to the technology NATURAL SURFACTANT FOR COSMETICS AND COSMETIC COMPOSITION COMPRISING THE SAME

The present invention relates to a natural surfactant for cosmetics and a cosmetic composition containing the same, and more particularly, to a natural surfactant for cosmetics which is polyoxyethyleneglycol-free and a cosmetic composition containing the same.

Conventionally, in order to protect the skin and maintain a healthy condition, various emulsifying cosmetics such as creams and lotion formulations have been used. These emulsifying cosmetics should be able to fully exhibit the effects of the active ingredients contained in the cosmetics, have a good feeling of use, and have excellent storage stability from the time the product is opened to the final use.

In recent years, awareness of skin safety has been heightened, and cosmetic compositions made from natural ingredients have been preferred, but natural surfactants tend to have lower emulsifying power than synthetic surfactants. In the case of oil in water (OW), it is difficult to realize stabilization. Therefore, it is considered that it is more difficult to realize a low viscosity formulation with a surfactant which is a natural surfactant with low emulsifying power.

In this connection, an emulsifier having a nonionic structure and having a polyoxyethylene group with less skin irritation than an emulsifier having an anionic or cationic structure has been widely used, but recently, an excessive amount of polyoxy Studies have shown that ethylene oxide (EO), which is highly reactive in the ethylene group, is liberated and can cause various skin diseases.

Therefore, in order to reduce such skin irritation, efforts have been made to develop products using an emulsifier containing no polyoxyethylene group, that is, a polyoxyethylene-free emulsifier. However, in most cases, the dispersibility of the pigment is poor and the emulsified state The stability is lowered due to anxiety, and the change of aging is severe, so that after the elapse of a long period of time, the contents are hardened and satisfactory results such as spreadability, adhesion feeling, and persistence are not obtained.

Recently, a natural emulsifier having a structure of a glucose derivative having a polyoxyethylene-free form and excellent emulsifying ability has been introduced as disclosed in Korean Patent Laid-Open Publication No. 2014-0047443. In this case, The emulsification becomes unstable and the hardness is not easily controlled as compared with the emulsifier having a polyoxyethylene group.

In order to produce a stable underwater type cosmetic composition with a combination of a naturally derived surfactant having a low emulsifying power as described above, it is necessary to find a combination of surfactants capable of securing the long-term stability as much as possible. Such a process is not easy and further, Finding the right area is also not easy.

Accordingly, surfactants having improved usability when used in polyoxyethylene-free oil in water (OW) emulsions and the like and having stability that does not cause separation of emulsion even at high temperature and low temperature have been developed It is expected that it can be widely applied in related fields.
