Abstract
A fabric softening composition having a viscosity of less than 150 cP, preferably less than 100 cP comprises an aqueous base, a cationic fabric softener and lanolin. The compositions may optionally contain viscosity control agents and nonionic emulsifying agents. Preferred compositions contain 0.5 to 30% cationic softener and 0.25 to 40% lanolin, the ratio of cationic softener to lanolin being from 20:1 to 1:20. The lanolin may be replaced by a lanolin-like material such as derivatives thereof or one or more of the active constituents of lanolin either extracted therefrom or derived from other sources. The presence of lanolin in the composition improves the viscosity and performance thereof.
