Patent Images
1. A method of exfoliating skin, wherein said method comprises:
- (a) applying to said skin a liquid composition comprising (i) water;
(ii) 5 to 20 wt. % of an anionic surfactant selected from the group consisting of alkyl ether sulfates, acyl isethionates, alkyl sulfosuccinates, alkyl amido sulfosuccinates, alkyl glyceryl ether sulphonates, methyl acyl taurates, alkyl phosphate esters, acyl sarcosinates, and mixtures thereof;
(iii) a cosurfactant selected from the group consisting of betaines, amidopropyl betaines, amidopropyl sultaines and mixtures thereof;
(iv) abrasive particles having a mean diameter of 40 to 400 micrometers and a bulk density of 1 to 4; and
(v) a viscosifer;
wherein the composition has a viscosity in the range 4000-8000 mPas measured at a shear rate of 10 s−
1;
wherein said composition is in rod micellar phase; and
wherein ratio of viscosity at 1 Hz;
10 Hz is between 2 and 5;
(b) washing the skin with the composition; and
(c) rinsing the composition off the skin.

Abstract
A viscous, liquid, skin washing composition comprising water, at least one surface active agent, abrasive particles and a viscosifier, CHARACTERISED IN THAT the viscosity of the composition is typically that of a shower gel, i.e. in the range 4000-8000 mPas measured at a shear rate of 10 s−1, the particles, preferably calcite, have a mean diameter of 40-400 micrometres and a bulk density of 1-4.
