Abstract
Abstract A skin cleansing composition containing, in a cosmetically acceptable medium, a structuring agent insoluble in this medium and formed of solid particles, which imparts a deformable solid appearance to the composition in which the medium is contained, this agent being capable of being removed from the skin using a diluent and the particles being at a concentration at least equal to the critical pigment charge volume.
