A concentrated fabric softening composition comprising water-insoluble cationic softener and a viscosity control system comprising a first component selected from non-cyclic hydrocarbons, fatty acids and esters thereof and fatty alcohols, and a second component which is a water-soluble cationic polymer having a molecular weight of 2000 to 250,000, selected from polyethylenimine, ethoxylated and propoxylated polyethylenimines and quaternized polyethylenimines. The composition has improved viscosity and stability at both normal and elevated temperatures.
