Abstract

Aqueous liquid laundry detergent compositions useful for cleaning fabrics wherein the compositions contain from about 0.05% to about 0.4%, by weight of the composition, of a cationic hydroxyethyl cellulose polymer having a degree of substitution of the cationic charge of from about 0.01 to about 0.20; from about 5% to about 30%, by weight of the composition, of a surfactant comprising at least one anionic surfactant and at least one nonionic surfactant; and from about 2% to about 15%, by weight of the composition, of fatty acid. Use of such aqueous liquid laundry detergent compositions for handwashing delicate fabrics. Use of such aqueous liquid laundry detergent compositions for machine washing of delicate fabrics, wherein the machine washing occurs at a delicate machine setting.
