摘要：通过分析6种化妆品级云母粉的粒度分布、形貌特征和润湿性特征,将指标量化,探讨国内外市售化妆品级云母粉的差异。结果表明:1^#、2^#云母粉的粒径分布窄,径厚比大,晶体形态和改性效果良好;3^#、4^#云母粉的改性效果优异;5^#、6^#云母粉表面改性效果差,且表面阶梯状明显;国内化妆品级云母粉晶体形态、表面平整度和润湿性需改进。

Abstract： The quality indexes such as particle size distribution, morphology characteristics and wettability characteristics of commercial cosmetics mica powders were analyzed, which were quantized to study the differences between domestic and overseas cosmetics mica powders. The results show that 1^# and 2^# mica powders have narrower particle size distribution, larger thickness-diameter ratio, better crystal shape and stronger modified effect. The modified effect of 3^# and 4^# mica powders is excellent. The modified effect of 5^# and 6^# mica powders is poor and the ladder morphology is obvious. Cosmetic mica powders should be improved from the aspects of morphology, crystal plane and wettability.
