Abstract
The invention relates to a cosmetic compact or cream powder which is provided with self-tanning agent and optionally light-protecting characteristics. The dihydroxy acetone (DHA) portion of said powder is fully used for coloration. The cosmetic powder contains a self-tanning agent selected from mixtures of DHA and aqueous mahakanni extract and mixtures of DHA with mahakanni and tulips extract, additional chromophore pigments, a wax or a mixture of several waxes, a powder basis and optionally additional cosmetic auxiliaries and active agents in stable homogeneous distribution. The inventive powder is produced by mixing the powder basis and a first portion of the pigments with the molten wax. The self-tanning agent and a second portion of the pigments in an aqueous-alcoholic suspension having a pH value ranging from 3-4 are subsequently added into the molten was mixture at 65 to 70° C. The entire mixture is steered, homogenised and cooled.
