Abstract: Effects of yeast enzymolysis conditions,such as dosage of UV irradiation cultivated protease,temperature,pH and time of the enzymolysis on the UV absorption performance of the yeast enzymolysis product solution were studied.Further,the live yeast cell derivative was applied in sun screening skin care cosmetic product.Experimental results showed that the optimum conditions for preparation of live yeast cell derivative are:addition of 2% of protease and 1% of cellulase into 10% (mass fraction) yeast solution,pH=6,temperature 52 ℃ and enzymolysis time of 26 h.The live yeast cell derivative can be used as additive in sun screening skin care cosmetics so as to increase maximum sun protection factor of the cosmetics by 128.2%.

Key words: additive of cosmetics, live yeast cell derivative, sun screening
