Abstract: Lotions were prepared by blending Paphia undulate small molecule peptides and aloe extract with separate mass fractions.Scavenging ratio of hydroxyl radical and superoxide anion radical of the lotion product were investigated,and a better formulation was identified.Experimental results showed that,under room temperature,the lotion product made from 0.8% of Paphia undulate small molecule peptides and 0.1% of aloe extract shows better antioxidizing performance.Scavenging ratio for hydroxyl radical of the lotion product reaches 73.7% and scavenging ratio for superoxide anion radical reaches 75.1%.Sensory organ indices and physicochemical indices of the lotion product are in conformity with that specified in trade standards of China cosmetic industry.

Key words: lotion, small molecule peptides, aloe extract, free radical
