An aqueous fabric conditioning composition comprises a cationic surfactant, an oil, a solvent and is in the form of a water-in-oil micro-emulsion. The cationic surfactant comprises either (a) quaternary ammonium compounds having at least one ester group and being formed from a parent fatty acid having a degree of unsaturation represented by an iodine value of from 20 to 140 or (b) quaternary ammonium compounds having two C8-C28 alkyl or alkenyl chains directly attached to the nitrogen and being formed from a parent fatty acid having a degree of unsaturation represented by an iodine value of from 0 to 20 or (c) mixtures of (a) and (b). The invention also relates to a process for treating fabrics and a method for preparing a fabric treatment composition.

L'invention concerne une composition aqueuse de conditionnement de tissus comportant un tensioactif cationique, une huile, un solvant et se présentant sous la forme d'une micro-émulsion d'eau dans l'huile. Le tensioactif est constitué soit a) de composés d'ammonium quaternaire ayant au moins un groupe ester et formés à partir d'un acide gras parent présentant un degré d'insaturation représenté par un indice d'iode se situant entre 20 et 140; soit b) de composés d'ammonium quaternaire ayant deux C8-C28 alkyle ou des chaînes d'alcényle directement attachées à l'azote et formés à partir d'un acide gras parent présentant un degré d'insaturation représenté par un indice d'iode se situant entre 0 et 20; soit c) des mélanges de a) et de b). L'invention concerne également un processus de traitement de tissus ainsi qu'un procédé de préparation d'une composition de traitement de tissus.
