Abstract

A cosmetic preparation in gel form is described which contains undissolved, water-swollen polymer particles and at the interface with gaseous substances forms reversibly a grainy, uneven, light-scattering surface and at the interface with solids forms reversibly a smooth, level, non-light-scattering surface. Preferred gel formers are superabsorbing polymers. A preferred use is the hair-end protection in permanent wave treatment.
