摘　　要：Foam cleanser is the most popular facial cleaning product in Asian market. However, soap-based product appears to be not physically stable under certain circumstance. For example, product viscosity decreases with the increase of temperature but goes up when the temperature goes down. More seriously, phase separation may occur for some products with time. Many efforts have been made to improve the stability of soap-based formulations mainly focusing on 1) adjust the fatty acids ratio;2) optimize saponification level;3) addition of thickeners and surfactants. Improvements have been made upon recent reports. However, required stability of the formulations at both high and low temperature is not satisfied yet. In this work, we introduced one type of non-ionic emulsifier to the soap-based formulation, through which to regulate the microstructure. It is seen that the stability is significantly improved at both high and low temperature, and the using performance is enhanced in the meantime.Foam cleanser is the most popular facial cleaning product in Asian market.
