A fabric softening composition comprising a water insoluble cationic fabric softening agent and a nonionic stabilising agent wherein the water insoluble cationic fabric softening agent is a biodegradable quaternary ammonium material with at least one ester link and the nonionic stabilising agent is selected from: i. a linear C8 to C22 alcohol alkoxylated with 10 to 20 moles of alkylene oxide, or ii. a C10 to C20 alcohol or mixtures thereof. The invention also provides a process for making the liquid fabric softening composition comprising the steps of i. mixing and heating the cationic fabric softening agent and nonionic stabilising agent to form a melt and ii. dispersing the melt in water.

Composition assouplissante pour tissus, renfermant un assouplissant cationique pour tissus, insoluble dans l'eau, et un stabilisateur non ionique. L'assouplissant cationique pour tissus, insoluble dans l'eau, est un composé d'ammonium biodégradable quaternaire avec au moins une liaison ester. Le stabilisateur non ionique est choisi parmi : i) un alcool linéaire en C8-C22, alcoxylé avec 10 à 20 moles d'oxyde d'alkylène; ii) un alcool en C10-C20 ou un mélange de ce type d'alcools. L'invention porte également sur un procédé pour la production d'une composition assouplissante liquide pour tissus, comprenant les étapes suivantes : i) mélange et chauffage de l'assouplissant cationique pour tissus et du stabilisateur non ionique, donnant un produit fondu; ii) dispersion du produit fondu dans l'eau.
