Sunless Tanning Creams from Chlorogenic Acid Extracted of Green Coffee Beans

The purpose of this study was to develop sunless tanning cosmetic creams from green coffee beans. Chlorogenic acid, which was extracted from green coffee beans, performed the change of the color of keratin in stratum corneum, used as active ingredient in the formulation. Extracted chlorogenic acid from green coffee beans were incorporated into four cosmetic cream bases, and then the tanning effect of the creams were evaluated as well as the stability test of the creams. The results showed that O/W cream base with extracted chlorgenic acid from green coffee beans had the most tanning activity at pH 4.5±0.5 and 40oC. The O/W cream also performed most stable than the other two types of cream. In conclusion, sunless tanning product from green coffee beans might be formulated in O/W type cream.
