LAUNDRY DETERGENT BARS CONTAINING FABRIC SOFTENING CLAY AND CELLULASE ENZYME

摘要

A laundry bar containing from about 10 % to about 60 % by weight anionic surfactant, from about 5 % to about 60 % by weight detergent builder, and from about 0.02 % to about 2 % by weight of cellulase enzymes. In a preferred embodiment, a laundry bar further comprises from about 0.5 % to about 30 % of a smectite-type softening clay, and optionally a polymeric clay flocculating agent at a level of about 0.001 % to about 30 % by weight of the fabric softening clay. A preferred clay flocculating agent is a poly(ethylene oxide) having an average molecular weight of 100,000 to about 10 million. An optionally-added detergent chelant is preferably alkali metal, alkali earth metal, and heavy metal salts of diethylenetriamine penta (methylene phosphonic acid), diethylenetriamine penta (acetic acid), ethylenediamine tetra (methylene phosphonic acid), ethylenediamine tetra (acetic acid), and mixtures thereof.
