化妆品用肤色纳米二氧化钛的制备

对使用三氧化二铁为改性剂改性二氧化钛，以制备肤色二氧化钛进行了研究。用混合和包覆两种不同的方法做对比，考察了氧化铁含量对颜色的影响，样品的分散性、紫外光屏蔽能力以及Fe2O3在样品中的稳定性并且对有毒元素含量进行了测试。结果表明，包覆制得的肤色二氧化钛在各个方面均优于混合法。

Preparation of Skin-color Nano Titania in Cosmetics

Using Fe_2O_3 as modifier to modify TiO_2,the preparation of skin-color TiO_2 have been studied.Through the contrast of two methods of mixing and surface coating,the influence of Ge_2O_3 content to color,ultraviolet radiation shielding ability,dispersivity and stability were examined,and tests to determine the content of poisonous element also were precessed.The results showed that the surface coating was a better method to prepare skin-color TiO_2.
