Laundry composition containing dye fixatives and cellulase
First Claim
1. Laundry compositions comprising a cellulase enzyme, wherein said cellulase enzyme consists essentially of a homogeneous endoglucanase component which is immunoreactive with an antibody raised against a highly purified 43 kD cellulase derived from Humicola insolens, DSM 1800, or which is homologous to said 43 kD endoglucanase, and a cationic dye fixing agent selected from the group consisting of the hydrochloride, acetate, methosulphate and benzyl hydrochloride salts of oleyldiethylaminoethylamide, oleylmethyl-diethylenediaminemethsulphate and monostearyl-ethylene diaminotrimethylammonium methosulphate;
- characterized in that the enzyme is present at a level of ranging from 0.05 CEVU/gram to 125 CEVU/gram finished product and that the dye fixing agent is present at levels comprised between 0.01% and 50% by weight.

Abstract
Laundry compositions, specifically fabric-conditioning compositions, to be used in the rinse cycle of laundry washing processes, are disclosed in order to improve color depth maintenance of colored fabrics upon single or multiple washing cycles. To achieve this, specific levels of cellulase and dye-fixing agents of the cationic type as well are used in the laundry compositions.
