Skin Care Effect of Cleansing Agents Using Polyglycerol Fatty Acid Esters

Abstract

: Cleansing agents such as facial cleansers and makeup removers are required not only to have high cleansing power against excess sebum and makeup, but also to be particularly gentle to the skin and hypoallergenic since they are used on the face. Therefore, we are focusing on polyglycerol fatty acid esters (PGFEs), which is highly safe and wide-ly used in leave-on type skin care products, and investigating its skin care effects when used as a cleansing ingredient.The results of various evaluations showed that cleaning formulations containing PGFEs didn’t disrupt skin barrier functions such as intercellular lipids, and were effective in suppress-ing multiple exfoliation of stratum corneum, reducing the size of keratotic plugs and carbonylation lev-el of stratum corneum around skin pores. This article introduces the skin care effects required of cleaning agents in terms of the water-holding capacity of PGFEs and its adsorption behavior on stra tum corneum.
