氧化疏水淀粉在祛痱粉中的应用研究

Study on application of oxidized hydrophobic starch in prickly-heat powder

以氧化-酯化-金属交联淀粉代替滑石粉配制祛痱粉,从休止角、压缩度、凝集度和平板角4个方面综合分析了不同配方法的粉体特性。得到最佳配方为原淀粉含量30%、氧化疏水淀粉含量65%,此时疏水性淀粉体现了其所具有的爽滑感,祛痱粉的肤感也不会过于干燥,而且,产品在细度上已经达到市场知名品牌的标准。

Oxidation-esterifi cation-metal crosslinked starch was used to substitute talcum to formulate the prickly-heat powder.The properties of the prickly-heat powders produced by different methods were analyzed in four aspects of slop angle,compression degree,aggregation degree and flat angle.The optimal condition was that 30%of native starch and 65%of oxidized hydrophobic starch.The hydrophobic starch had smooth feeling,and the prickly-heat powder’s skin feeling was not too dry.Moreover,the product achieved the standard that used by some well-known brands in the market.
