Abstract
Powdery pearlescent pigment compositions comprising individual particles of a flaky pearlescent pigment coated with 1 to 50 weight percent of a solid polymer, optionally containing wetting agents, fillers, additional coloring agents, UV-absorbers or scenting agents, are produced by combining a suspension of a flaky pearlescent pigment with a solution of a polymer, possibly containing other substances, and subsequently depositing polymer on the pigment flakes. The compositions can be used as pigments in cosmetics and can be stored and shipped as dry powders without loss of properties.
