荸荠OSA改性淀粉在润肤乳液的应用研究

Application of Water Chestnut OSA Modified Starch in Moisturizing Lotion

以荸荠淀粉为原料,经辛烯基琥珀酸基酐改性后得到乳化性较好的荸荠OSA改性淀粉,将所得的荸荠OSA改性淀粉应用于润肤乳液中,并对产品的综合性能进行了测试和评价。通过L9(34)正交实验确定乳化剂的最佳配比为硬脂酸甘油酯3%、吐温-601%、黄原胶0.4%,对体系的稠度、黏度及感官评价进行分析,确定体系乳化温度80℃、乳化时间15min,荸荠OSA改性淀粉添加量为1%。在此条件下添加水相、油相成分,制备润肤乳液,所得产品保湿率达35.84%,理化性能稳定、质地细腻均匀。

A test including three steps is made in this research.First of all,the modified starch of water chestnut OSA with good emulsifying property was obtained by using water chestnut starch as raw material and modified by octenyl succinic anhydride.Then the modified starch of water chestnut OSA with good emulsifying property is used to prepare moisturizing lotion product.Finally,the comprehensive performance of the product was tested and evaluated.It is found that,determined by using the orthogonal experiment of L9(34),the optimum base composition of emulsifiers were 3%glycerol monostearate,1%tween-60,0.4%xanthan gum.The consistency,viscosity tests and sensory evaluation showed that the emulsifying temperature was 80℃,emulsifying time was 15 min,and the water chestnut modified starch addition was 1%.Under such conditions,adding water phase and oil phase composition,the product performance testing and sensory evaluation were accomplished.Results showed that particles of the moisturizing lotion product were homogeneous and the physical and chemical properties were stable.The results also demonstrated that the moisturizing lotion product displays good moisturizing efficacy and the moisturizing efficiency could reach to 35.84%.
