The present invention relates to a laundry detergent composition comprising glycosyl hydrolase. The compositions of the present invention also comprises a polymer that, when used in combination with the glycosyl hydrolase, enables compaction of the surfactant system to be achieved without loss in fabric cleaning performance. Preferably, the composition of the present invention comprises a combination of two polymers, a glycosyl hydrolase and detersive surfactant, preferably low levels of detersive surfactant. Most preferably, the laundry detergent composition of the present invention comprise: (i) a glycosyl hydrolase having enzymatic activity towards both xyloglucan and amorphous cellulose substrates, wherein the glycosyl hydrolase is selected from GH families 5, 12, 44 or 74; (ii) detersive surfactant; (iii) amphiphilic alkoxylated grease cleaning polymer; (iv) a random graft copolymer comprising: (a) hydrophilic backbone comprising monomers selected from the group consisting of: unsaturated C 1- C 6 carboxylic acids, ethers, alcohols, aldehydes, ketones, esters, sugar units, alkoxy units, maleic anhydride, saturated polyalcohols such as glycerol, and mixtures thereof; and (b) hydrophobic side chain(s) selected from the group consisting of: C 4- C 25 alkyl group, polypropylene, polybutylene, vinyl ester of a saturated C 1 -C 6 mono-carboxylic acid, C 1- C 6 alkyl ester of acrylic or methacrylic acid, and mixtures thereof; and (v) a compound having the following general structure: bis((C 2 H 5 O)(C 2 H 4 O)n)(CH 3 )-N + -C x H 2x -N + -(CH 3 )-bis((C 2 H 5 O)(C 2 H 4 O)n), wherein n = from 20 to 30, and x = from 3 to 8, or sulphated or sulphonated variants thereof. Most preferably the composition is in the form of a liquid.
