Design of Emulsion Film for Cosmetics with High Function and Good Feeling

Abstract

An emulsion film is formed when I apply emulsion cosmetics on skin. I tried to investigate the state of emulsion film, because this state affected the moisturizing and occlusive functions, feelings of emulsion cosmetics significantly. For emulsions used polyoxyethylene-type surfactant, droplets disappear after the film is formed, whereas used polyglycerin-type surfactants, the droplets shape is retained even. The moisturizing and occlusive functions show good results together. The stratum corneum is improved significantly after continuous use. Hydration gel film is formed in the upper side in the case of using alginic acid propylene glycol ester. Therefore I am able to get good feeling, no sticky even if oil content in emulsion is increased.
