Compositions containing at least one organic phospholipid capable of forming bilayers in aque-ous solution; and at least one amphoteric surfactant and at least one nonionic surfactant, each present in an amount by weight equal to or greater than the amount of the phospholipid; where the phospholipid and surfactants are present in a combined amount sufficient to allow at least one water-insoluble ingre-dient selected from waxes and unneutralized and par-tially neutralized water-insoluble polymers, resins, and latexes to be incorporated into an aqueous solu-tion. A delivery system containing the composition and methods for styling hair and for treating kerati-nous substances are also disclosed.
L'invention concerne des compositions renfermant au moins un phospholipide organique capable de former des bicouches dans une solution aqueuse; au moins un tensioactif amphotère et au moins un tensioactif non ionique, chacun présent en dose en poids au moins égale à celle du phospholipide. Le phospholipide et les tensioactifs sont présents en dose combinée suffisante pour permettre d'incorporer, dans une solution aqueuse, au moins un ingrédient insoluble dans l'eau choisi parmi des cires et des polymères, résines et latex non neutralisés et partiellement neutralisés insolubles dans l'eau. L'invention concerne enfin un système d'administration comprenant la composition et des procédés permettant de modeler la coiffure et de traiter des substances kératiniques.
