化妆品用硅微米球形粉吸油值的测定

Determination of Oil Absorption Value of Silicon Micron Spherical Powder Used for Cosmetics

硅微米球形粉作为一种化妆品原料,能赋予化妆品良好的肤感和多种优良性状,为让硅微米球形粉更好地应用于化妆品配方中,确定其与不同油脂的配伍比例,测定其吸油值尤为重要。通过综合国家标准和前人的方法测定了7种硅微米球形粉针对9种油脂的吸油值,结果表明有活动区域的硅微米球形粉针对不同油脂的吸油值差异性极大,且吸油效果较好,无机硅微米球形粉吸油值大于无活动区域的有机硅微米球形粉,且二者针对不同油脂的吸油值差异性较小。该试验结果可为硅微米球形粉配伍于化妆品配方中提供参考。

Silicon micron spherical powder(SMSP), as a new type of cosmetic raw material, can provide cosmetics a good skin feeling and a variety of good properties. In order to make SMSP be better applied in cosmetic formulas, it is particularly important to determine its compatibility ratio with different types of oils and the oil absorption value(OAV). In this experiment, the OAV of seven kinds of SMSP to nine kinds of oils were determined by using comprehensive national standards and previous methods. The results showed that the SMSP with an active area had the highest OAV and significant difference of the OAVs towards existed different oils. The OAV of the inorganic SMSP was higher than that of the organic SMSP without the active area, and both of their OVAs for different oils were less different. The experimental results can provide a reference for the compatibility of SMSP in cosmetic formulations.
