A Study on the Characteristics of Microemulsion Containing Isoflavone

Microemulsion is stable to aggregation, sedimentation, fusion and has 3nm{sim}200nm of particle size which is transparent and semitransparent. The isoflavone as a derivatives of Flavone is colorless crystalline compounds. It has similar basic structure to steroid materials which is hormone that acts to skin physiological phenomenon. On this study, we tried to search and demonstrate system content rate of dermal translocation system for cosmetics using O/W type microemulsion containing isoflavone. We manufactured O/W microemulsions by phase inversion emulsification method. It s was found that POE(20) monostearate with HLB value 14 caused microemulsion to be formed, which had 4nm{sim}18nm of average diameter and $3nm{\sim}33nm of particle size distribution. Apparent viscosities of the microemulsions have increased in proportion to add surfactant dose.
