LAUNDRY DETERGENT COMPOSITION CONTAINING GLYCOSYL HYDROLASE Russian patent published in 2012 - IPC C11D3/386 C11D3/37 

FIELD: chemistry.

SUBSTANCE: present invention relates to a laundry detergent composition containing glycosyl hydrolase, having enzyme activity with respect to both xyloglucan and amorphous cellulose substrates, where the glycosyl hydrolase is selected from GH 5, 12, 44 or 74 families; (ii) 0.05-10 wt % amphiphilic alkoxylated fat-removing polymer; and (iii) 2-50 wt % synthetic detergent. The present invention also relates to a laundry detergent composition containing: (i) glycosyl hydrolase, having enzyme activity with respect to both xyloglucan and amorphous cellulose substrates, where the glycolsyl hydrolase is selected from GH 5, 12, 44 or 74 families; (ii) a random graft polymer containing: (a) a hydrophilic backbone chain containing monomers selected from a group consisting of: alcohols, alkoxyl links and maleic anhydride; and (b) hydrophobic side chain(s) selected from a group consisting of: vinyl ester of saturated C₁-C₆ monocarboxylic acid, C₁-C₆ alkyl ester of acrylic or methacrylic acid; and (iii) 2-50 wt % synthetic detergent. The present invention also relates to a method of washing fabrics.

EFFECT: improved dirt-removing profile and whiteness retention profile with low content of surfactants.
