摘要:
The present invention relates to a composite pigment comprising at least one small particle with a mean particle size of more than 100 nm and less than 1 μm, preferably less than 600 nm, and more preferably less than 400 nm, wherein the surface of the small particle is at least in part covered with at least one layer comprising at least one inorganic solid UV filter and/or at least one coloring pigment. The composite pigment can be prepared by a method comprising a step of subjecting the small particle and at least one inorganic solid UV filter and/or at least one coloring pigment to a mechanochemical fusion process such as a hybridizer process. The composite pigment can be advantageously used as a component for a cosmetic composition.
摘要(中):
本发明涉及一种复合颜料,其包含至少一种平均粒径大于100nm且小于1μm,优选小于600nm,更优选小于400nm的小颗粒,其中小颗粒的表面 颗粒至少部分地被包含至少一层包含至少一种无机固体UV过滤器和/或至少一种着色颜料的层覆盖。 复合颜料可以通过包括以下步骤的方法来制备:将小颗粒和至少一种无机固体紫外线过滤器和/或至少一种着色颜料进行机械化学融合过程如杂化过程的步骤。 复合颜料可以有利地用作化妆品组合物的组分。
