Abstract
Abstract A bleach-stable fabric detergent and/or softening composition comprising effective amounts of a softening agent selected from the group consisting of a urea, diurea, thiourea, dithiourea and mixtures thereof represented by the formulae: 1. RNHCXNH(CH 2 ) n NH 2 , and 2. RNHCXNH(CH 2 ) n NHCXNHR, wherein R is an alkyl group containing 2-18 carbons or an aryl group, X is oxygen or sulfur, and n is 2-12, said softener being compatible with surfactants and other ingredients normally found in detergent formulations.
