Determination of Chemical and Physical Properties of Soybean as Skin Care Product

Abstract

The uses of Hydroquinone, Alpha Arbutin and Glitathione in whitening products can thin the skin layer and harmful for human. This study is conducted to determine the properties of soybean milk as an alternative ingredients in whitening prodct . The formulations of thia soybean emulsions are characterized vie spectroscopy and skin analysis. The major components of soy are phospholipids, such as phosphatidylcholine and essential fatty acids acts as active compounds for whitening. The soymilk is extracted from soybean and added into the emulsion woth the designated amount. The skin analysis shows that the emulsion with soymilk (Formulation 3) gives the best result with 30.2341 melanin in skin colour test and the highest value in hydration and TEWL test.
