摘要：
Preparations in the form of an emulsion, containing a hydroxy carboxylic acid alkyl ester from a C2-C6 hydroxy carboxylic acid and a C8-C22 alcohol as oily components in addition to at least 0.1 wt.% spherical polymer powder with a high specific surface of at least 1m2/g dispersion, suitable for use as skin care agents for reducing the oily appearance of skin. Preferably, the preparation contains 1-10 wt.% hydroxy carboxylic acid alkyl ester and 0.1-5 wt.% spherical polymer powder. Polymethacrylate, polyamide, styrol-divinylbenzol copolymers, polyethylene and polypropylene powders or silicon polymers are suitable polymer powders.
