A composition for cleaning or caring for the skin, teeth or hair or for cleaning smooth surfaces in described, which has an aqueous phase containing a pregelatinized, crosslinked starch selected from a C,-C,hydroxyalkyl starch and a C,-C,acyl starch. Preference is given to hydroxypropyl di-starch phosphate or di-starch C,-C,-alkanoate or alkenoate. The starch acts 1) as a stability improver, 2) as a viscosity regulator, 3) as a (co)emulsifier, 4) as a skin feel improving agent and 5) as an agent for improving hairdressing characteristics.

Starchy cleaning and cosmetic care preparations

The present invention relates to thickened personal care compositions which utilize a thickening amount of an acrylate-based polymeric rheology modifier prepared by polymerization of a C.sub.1 -C.sub.6 alkyl ester of acrylic acid and/or a C.sub.1 -C.sub.6 alkyl ester of methacrylic acid, a monomer chosen from a vinyl-substituted heterocyclic compound containing at least one of a nitrogen or sulfur atom, (meth)acrylamide, a mono- or di-(C.sub.1 -C.sub.4)alkylamino (C.sub.1 -C.sub.4)alkyl (meth)acrylate, a mono or di-(C.sub.1 -C.sub.4)alkylamino (C.sub.1 -C.sub.4)alkyl (meth)acrylamide, and, optionally, an associative monomer.
