Abstract
A stable, pourable and water dispersible liquid fabric softening composition is provided comprising (a) from about 2% to about 25% of one or more fabric softening compounds selected from among quaternary ammonium compounds and amine compounds; (b) from 0 to about 10% of a co-softening ingredient; and (c) from about 0.02% to about 3% of a defined fatty alcohol ethoxylate-diurethane polymer as a thickener to provide commercially desirable viscosities without adversely affecting the physical stability of the composition. The balance of the composition is comprised of water and optional ingredients such as an acid, an emulsifier and adjuvants.
