Abstract

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.sub.2 -C.sub.5 hydroxyalkyl starch and a C.sub.2 -C.sub.18 acyl starch. Preference is given to hydroxypropyl di-starch phosphate or di-starch C.sub.4 -C.sub.18 -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.
