Market and technical trend of cleansing oils

Abstract

Consumers’ makeup behavior has changed greatly in past several years. Lipsticks and foundation were mainly used before, but recently mascara is becoming widely used to emphasize their eyes. Following this change, the market for makeup remover also changed. That is, the market for cleansing oil, which has superior eye makeup removing ability, expanded quickly. The cleansing oils contain oils and surfactants. The latter emulsify the oils and help them to be washed away. Multichain non‐ionic surfactants are usually used for their high emulsifying ability and for their low safety risk. However, conventional cleansing oils cannot be used with wet hands, because oils are emulsified, and makeup removing ability obviously declines. Recently, a new cleansing oil that can be used with wet hands was developed. As it can solubilize a lot of water in itself, it retains its makeup removing ability in spite of the water contamination. To realize the high water solubilizing ability, it is important to use a surfactant that has a lipophobic group like the hydroxyl group as well as to control the HLB of the entire system.
