1. A detergent composition comprising a bacterial alkaline enzyme exhibiting endo-beta-1,4-glucanase activity and a ethoxylated polymer comprising:
- (a) a random graft copolymer comprising a hydrophilic backbone comprising monomers comprising unsaturated C1-6 acids, ethers, alcohols, aldehydes, ketones or esters, sugar units, alkoxy units, maleic anhydride and saturated polyalcohols such as glycerol, and mixtures thereof, and hydrophobic side chains comprising a C4-25 alkyl group, polypropylene;
polybutylene, a vinyl ester of a saturated monocarboxylic acid containing from about 1 to about 6 carbon atoms;
a C1-6 alkyl ester of acrylic or methacrylic acid; and
a mixture thereof;
(b) a modified polyethyleneimine polymer wherein the modified polyethyleneimine polymer comprises a polyethyleneimine backbone of about 300 to about 10000 weight average molecular weight;
the modification of the polyethyleneimine backbone is;
(1) one or two alkoxylation modifications per nitrogen atom in the polyethyleneimine backbone, the alkoxylation modification comprising the replacement of a hydrogen atom by a polyalkoxylene chain having an average of about 1 to about 40 alkoxy moieties per modification, wherein the terminal alkoxy moiety of the alkoxylation modification is capped with hydrogen, a C1-C4 alkyl or mixtures thereof;
(2) a substitution of one C1-C4 alkyl moiety and one or two alkoxylation modifications per nitrogen atom in the polyethyleneimine backbone, the alkoxylation modification comprising the replacement of a hydrogen atom by a polyalkoxylene chain having an average of about 1 to about 40 alkoxy moieties per modification wherein the terminal alkoxy moiety is capped with hydrogen, a C1-C4 alkyl or mixtures thereof;
or(3) a combination thereof;
(c) a modified polyaminoamide comprising formula (I)

Abstract
This invention relates to detergent compositions comprising bacterial alkaline enzymes exhibiting endo-beta-1,4-glucanase activity (E.C. 3.2.1.4) and an ethoxylated polymer selected from the group consisting of polyethylene glycol/vinyl acetate graft copolymer; a ethoxylated (and optionally propoxylated) polyethyleneimine; a zwitterionic and ethoxylated polyamidoamine; ethoxylated (and optionally propoxylated) comb polycarboxylate; and mixtures thereof.
