摘要: 通过CM825型皮肤水分测试仪和皮肤斑贴试验,研究聚谷氨酸的保湿功效及安全性。结果表明:不同分子量和质量分数的聚谷氨酸在保湿特性上差异较大,其中分子量为1 200 kDa的聚谷氨酸在质量分数为0.1%时,保湿效果最好;受试者涂抹该受试物2和4 h后皮肤水分含量的变化率分别为(103.9±0.2)%和(112.2±0.2)%,接近现在广泛使用的保湿剂透明质酸钠的(114.0±0.3)%;皮肤斑贴试验结果表明聚谷氨酸对皮肤安全、无刺激性。

Abstract: The moisture retention capacity and safety evaluation of poly-γ-glutamate (γ-PGA) were studied by using CM825 skin moisture tester and the human skin patch test method.Results showed that γ-PGA with separate molecular weight and separate mass fraction displays rather different moisturizing properties respectively,and γ-PGA with molecular weight of 1 200 kDa and mass fraction of 0.1% displays the best moisture retention capacity.After smearing test with the γ-PGA for 2 and 4 h separately,change of skin moisture content becomes (103.9±0.2)% and (112.2±0.2)% respectively,which is near to the value of the widely used moisturizer sodium hyaluronate (114.0±0.3)%.Results of the skin patch test showed that the γ-PGA is safe and causes no irritation to human skin.

Key words: poly-γ-glutamate, moisture retention capacity, safety evaluation
