摘要:
The present invention relates to a composite pigment comprising a substrate, said substrate being at least in part covered by at least one layer comprising at least one solid organic UV filter. The composite pigment can be prepared by a method comprising a step of subjecting a substrate, at least one solid organic UV filter, and optionally at least one solid inorganic UV filter, at least one additional 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.
