<p>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.</p> |
