ABSTRACT:
Fabric softening compositions comprise alcoholic solutions or aqueous dispersions of a mixture of quaternary ammonium compounds having the general formula: ##STR1## in which X represents a quaternary anion, for example chloride, bromide, iodide, methylsulphate, R.sub.1 and R.sub.2, which may be the same or different within a molecule, are long chain alkyl groups containing from 13 to 19 carbon atoms in each group, the groups being both straight chain and branched and in which the amount of branching is in the range between 30% and 70%, and particularly mixtures of quaternary compounds in which the substituents R.sub.1 and R.sub.2 are alkyl groups containing 13 and 15 carbon atoms comprising 65 to 75% C.sub.13 groups with 35 to 25% C.sub.15 groups (the percentages being calculated on the total of long chain alkyl groups) with 40 to 55 wt % straight chain and 60 to 45 wt % 2-alkyl branched chain where the 2-alkyl groups is predominantly methyl.
