护肤品油类基质原料的光谱特性分析

护肤品常用的油类基质原料种类较多，其光谱特性有较大的区别，选择紫外吸收特性较好的基质原料，将使护肤品的防晒效果更加明显。文章主要是用分光光度法测定分析护肤品6种常用油类基质原料的光谱特性。分析比较T-λ光谱特性曲线说明，蓖麻油对紫外光有很好的吸收，对近红外光相比较有好的吸收，这表明护肤类产品选用蓖麻油作为基质原料，防晒效果明显增强，可以提高产品的质量。更好突出护肤类产品的防晒和保健作用。

Analysis of Spectral Properties of Oil Matrix Raw Materials in Skin Care Products

There are many kinds of oil matrix raw materials used in skin care products. Their spectral properties are different. The matrix raw material that has better ultra-violet absorption will enhance the sun-screening agent effect obviously. In the present article the spectral properties of six oil matrix raw materials often used in skin care products were mainly measured and analyzed by spectrophotometer. The analysis of T-lambda spectra shows that castor oil can absorb ultraviolet as well as near infrared light. It was shown that castor oil chosen as the matrix raw material will improve the effect of sun-screening agent and enhance the products. The function of sun-screening agent and skin health care product will stand out clearly.
