title: [Analysis of spectral properties of oil matrix raw materials in skin care products].
abstract: 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.
