Disclosed are topical skin care compositions which comprise from about 0.1 % to about 20 % by weight of an amine oxide surfactant, from about 0.1 % to about 20 % by weight of an anionic surfactant, from about 0.001 % to about 20 % by weight of a skin active agent, from about 40 % to about 99 % by weight of water, and dispersed surfactant complex formed prior to or during formulation of the composition, which complex comprises from about 25 % to about 100 % of the cationic surfactant of the composition and from about 25 % to about 100 % of the anionic surfactant of the composition. The skin care compositions are useful for clarifying the skin and reducing pore size, while providing improved deposition or efficacy of skin active agents onto the surface of the skin, milder cleansing of the skin, and improved skin feel benefits.

L'invention porte sur des produits pour soins de la peau à usage topique comportant d'environ 0,1 % à environ 20 % en poids d'un tensioactif d'oxyde d'amine, d'environ 0,1 % à environ 20 % en poids d'un tensioactif anionique, d'environ 0,001 % à environ 20 % en poids d'un agent agissant sur la peau, d'environ 40 % à environ 99 % en poids d'eau, et un complexe dispersé de tensio-actifs formé avant ou pendant la préparation de la composition ledit complexe représentant d'environ 25 % à environ 100 % du tensioactif cationique de la préparation et d'environ 25 % à environ 100 % du tensioactif anionique de la préparation. Ces produits pour soins de la peau clarifient la peau, réduisent la taille des pores tout en améliorant le dépôt ou l'efficacité des agents agissant sur la peau, assurent un nettoyage plus doux et de nouveaux avantages en matière de toucher de la peau.
