TH25153U - Formula and production process of skin tone correcting cream containing extracts of giant tamarind seed coat - Google Patents

Abstract

This invention is the development of skin tone cream containing the extract of giant tamarind seed coat which has the property of brightening skin tone because the extract of giant tamarind seed coat has the property of inhibiting the creation of tyrosinase enzyme in the process of creating skin pigments and the extract is obtained by peeling giant tamarind by soaking in dry ice which preserves the efficiency of the active ingredient more than the peeling method by boiling. The skin tone cosmetic cream containing the extract of giant tamarind seed coat which is a natural extract reduces the import of synthetic skin tone agents from abroad such as kojic acid, increases the value of giant tamarind seeds which have to be discarded, and provides an alternative for farmers to sell tamarind seeds or extract them to develop skin tone cosmetic products for sale.
