Abstract
The present invention relates to a cosmetic and personal care preparation or formulation comprising (a) from 0.0001 to 90% by weight of a gloss pigment comprising (a1) a core consisting of a substantially transparent or metallically reflecting material, and (a2) at least one coating substantially consisting of one or more silicon oxides, the molar ratio of oxygen to silicon being on average from 0.03 to 0.95 and (b) from 10 to 99. 9999% of a (cosmetically) suitable carrier material, based on the total weight of the cosmetic preparation or formulation.
