A liquid cleansing composition comprising a cleansing surfactant, an adsorbed skin-care agent, adsorptive polymeric particles having an adsorption capacity of at least 2 g of skin care agent per gm of dry polymeric particles, a polymeric thickening agent having a molecular weight in the range of 500,000 - 10,000,000 Dalton, a water-soluble polymer having a molecular weight in the range of 200 - 50,000 Dalton, and a hydrophilic liquid, the said cleansing composition having the following features i) the low molecular weight, water- soluble polymer component functions as a foam-boosting and thixotropy- boosting agent; ii) the ratio of the Brookfield viscosity at 1 rpm of spindle speed to the Brookfield viscosity at 100 rpm of spindle speed is at least 10; and iii) the foam-volume is at least 20% higher with the water-soluble, polymeric, foam-boosting component than without it.

La présente invention concerne une composition nettoyante comprenant un tensioactif nettoyant, un agent de soin pour la peau adsorbé, des particules polymères adsorbantes ayant une capacité d'adsorption d'au moins 2 g d'agent de soin pour la peau par gm de particules polymères sèches, un agent épaississant polymère ayant un poids moléculaire dans la gamme allant de 500 000 à 10 000 000 Dalton, un polymère soluble dans l'eau ayant un poids moléculaire allant de 200 à 50 000 Dalton, et un liquide hydrophile, ladite composition nettoyante ayant les caractéristiques suivantes i) le composant polymère soluble dans l'eau et à faible poids moléculaire fonctionne comme un agent renforçateur de mousse et de thixotropie ; ii) le rapport entre la viscosité Brookfield à 1 tpm de vitesse de rotation et la viscosité Brookfield à 100 tpm de vitesse de rotation est au moins de 10; et iii) le volume de mousse est au moins 20% supérieur avec le composant polymère soluble dans l'eau et renforçateur de mousse que sans.
