Abstract
The invention comprises dermatological or cosmetic preparations comprising a triple combination of anionic polymer and two rheology modifying polymers which increase the viscosity of the preparation by at least 200% at a high shear rate and do not increase the viscosity at a low shear rate by more than 50%, thus imparting an improved sensory richness during spreading, in comparison to preparations without this combination.

1-10. (canceled)
A cosmetic or dermatological preparation, wherein the preparation comprises at least one polymeric anionic thickener and at least two further rheology-modifying polymers.
A method of increasing the viscosity of a cosmetic or dermatological preparation comprising at least one polymeric anionic thickener, wherein the method comprises incorporating in the preparation at least two further rheology-modifying polymers which increase the viscosity of the preparation at high shear by at least 200% and at low shear by not more than 50%.
A method of increasing the richness of a cosmetic or dermatological preparation comprising at least one polymeric anionic thickener upon spreading without increasing the proportion of lipids, wherein the method comprises incorporating in the preparation at least two further rheology-modifying polymers which increase the viscosity of the preparation at high shear by at least 200% and at low shear by not more than 50%.
