The invention provides personal care products comprising fatty ethoxylated dimeric urethane compounds that enhance the viscosity of constituent water based surfactant systems. In compositions and methods of the invention, ethoxylated nonionic, urethane dimers increase the viscosity of water based surfactant systems and serve as thickeners. These thickeners produce clear solutions in combination with surfactants and can be made sufficiently water soluble to produce clear solutions in water. The thickeners are compatible with anionic, cationic, amphoteric and nonionic surfactants and are functional and stable over a wide pH range.

La présente invention concerne des produits de soins personnels qui comprennent des composés uréthanne dimériques gras qui améliorent la viscosité de systèmes de tensioactif à base d'eau, en tant que constituant. Dans les compositions et les procédés selon l'invention, les dimères uréthanne non ioniques éthoxylés améliorent la viscosité de systèmes de tensioactif à base d'eau et font office d'épaississants. Ces épaississants forment des solutions transparentes en combinaison avec des tensioactifs et peuvent être rendus suffisamment solubles dans l'eau pour former des solutions transparentes dans l'eau. Les épaississants sont compatibles avec les tensioactifs anioniques, cationiques, amphotériques et non ioniques et sont fonctionnels et stables sur une gamme de pH étendue.
