Self-Organization of Amphiphilic Substances and Their Applications

Abstract

Amphiphilic substances such as bio lipids and surfactants having self-organization property form molecular assemblies (self-organized assemblies) with geometric structures related with the critical packing parameter (CPP) of each molecule in the aqueous phase. These self-assemblies have high internal phase ratio emulsification property, enhancing effect on skin penetration of actives, skin moisturizing effect and improvement effect on skin condition. Therefore these self-assemblies can be successfully used for manufacturing highly functional cosmetics and external drugs.
