A fabric conditioning composition comprising a cationic fabric softening compound dispersed in water is found to have surprisingly improved viscosity stability if a stabilising system comprising at least one salt of a multivalent inorganic anion or non-sequestering multivalent organic anion is present. The invention is particularly suitable for use with quaternary ammonium material comprising a compound having two C12-18 alkyl or alkenyl groups connected to the molecule via at least one ester link. Preferably, the mixture comprises sodium chloride and sodium sulphate. Preferably, there is additionally at least one salt of a univalent anion.
L'invention concerne une préparation de conditionnement de tissus, comprenant un composé cationique assouplisseur de tissu, dispersé dans l'eau, et présentant une stabilité de viscosité améliorée si un système stabilisant comprenant au moins un sel d'un anion inorganique polyvalent ou d'un anion organique polyvalent non séquestrant est présent. La préparation de l'invention convient particulièrement à l'utilisation avec un matériau d'ammonium quaternaire comprenant un composé possédant deux groupes alcényle ou alkyle C12-18 liés à la molécule par au moins une liaison ester. Le mélange comprend, de préférence du chlorure de sodium et du sulfate de sodium et au moins un sel d'un anion monovalent.
