Abstract
The present invention provides the use of a mixture of cationic surfactants to disperse in water a quaternary ester ammonium component comprising one or more compounds of formula (IV), wherein the mixture of cationic surfactants is obtainable by a process comprising: (a) the esterification of a hydroxyl group-containing compound or a mixture of hydroxyl group-containing compounds with a mixture of compounds containing one or more carboxylic groups, and (b) cation formation from the reaction products of Step I. The invention also provides compositions and uses thereof. Advantageously the dispersions of the invention are highly stable. The quaternary ester ammonium component comprises one or more compounds of are of formula (IV)
