Claims7
A liquid fabric conditioning composition comprising
- (a) from about 2% to about 11% by weight of the composition of non-cyclic quaternary ammonium cationic fabric conditioning agent;
- (b) from about 1% to about 5% by weight of the composition of a nonionic fabric conditioning agent selected from the group consisting of:
- (i) C.sub.10 -C.sub.26 fatty acid esters of mono- or polyhydroxy alcohols containing 1 to 12 carbon atoms;
- and
- (ii) esters of fatty alcohols having from 12 to 24 carbon atoms in the alkyl chain and mono- or poly-carboxylic acids having from 1 to 8 carbon atoms in the alkyl chain;
- whereby the total number of carbon atoms in the ester is equal to or greater than 16;
- (c) from about 0.1% to about 1.3% by weight of the composition of protonated di-polyethoxy mono-alkyl amine;
- (d) from about 1% to about 6% by weight of the composition of a lower alcohol;
- and
- (e) water;
- wherein the total amount of cationic plus nonionic fabric conditioning agents is no more than about 11%.
