STABLE QUATERNARY AMMONIUM COMPOSITIONS

摘要

The invention provides stable compositions comprising ester-containing quaternary ammonium material and one or more stabilising agent(s) chosen from: a) urea, b) urea derivatives, c) organic compounds with at least one free lone pair of electrons chosen from: i) primary amines, ii) secondary amines, and/or iii) tertiary amines, iv) glycerol wherein the composition is a liquid, molten or semi-solid containing 10 % or less water, and when glycerol is used the ammonium material has 2 or less CH3 groups attached to the quaternary nitrogen atom.
