A stable aqueous foaming surfactant dispersions comprise from 5 to 50 weight % of a surfactant composition comprising at least one foaming surfactant, at least one fatty amphiphile and optionally at least one hydrocolloid; and from 50 to 95 weight % of water and/or at least one foaming surfactant, particularly including at least one anionic surfactant, at least one fatty amphiphile and optionally at least one hydrocolloid, the dispersion also including emulsified therein at least one emollient. Such formulations are particularly useful in the manufacture of 2-in-1 formulations including emollients and/or similar materials. Methods are described for making surfactant formulations especially 2-in-1 formulations particularly using a pre-formed solid blend of foaming surfactant, at least one fatty amphiphile and hydrocolloid.

L'invention concerne des dispersions tensio-actives moussantes aqueuses stables, composées de 5 à 50 % en poids d'un élément tensio-actif contenant au moins un agent tensio-actif moussant, au moins un amphiphile gras et éventuellement au moins un hydrocolloïde; ou encore 50 à 95 % en poids d'eau et/ou au moins un agent tensio-actif moussant, contenant notamment au moins un agent tensio-actif anionique, au moins un amphiphile gras et éventuellement au moins un hydrocolloïde, la dispersion contenant en outre un émollient en émulsion. Ces éléments sont particulièrement utiles dans la fabrication de formulations 2 en 1 contenant des émollients et/ou d'autres agents analogues. L'invention concerne aussi des méthodes permettant d'élaborer des compositons tensio-actives notamment des compositions 2 en 1, contenant un complexe solide préformé composé d'un agent tensio-actif moussant, et d'au moins un amphiphile gras et un hydrocolloïde.
