STABILISING FABRIC SOFTENING COMPOSITIONS USING AN OILY SUGAR DERIVATIVE

摘要

The invention provides a method of improving the viscosity stability upon storage of a fabric softening composition comprising: (a) 0.5 % to 30 % by weight of at least one ester-linked quaternary ammonium fabric softening compound, (b) perfume, and (c) an alkoxylated nonionic surfactant, by the inclusion in the composition of at least one oily sugar derivative in a weight ratio of softening compound to sugar derivative in the range 30:1 to 1:1. Also provided are a fabric softening composition produced by the method of the invention, a method of treating fabric by applying thereto said composition and the use of a particular oily sugar derivative to provide viscosity stability at 37 °C to a fabric softening composition comprising 0.5 % to 30 % by weight of at least one ester-linked quaternary ammonium fabric softening compound, a perfume and an alkoxylated nonionic surfactant.
