    摘要: A solid particulate laundry detergent composition including: (a) polyethylene glycol polymer including a polyethylene glycol backbone and polyvinyl acetate side chains, wherein the average molecular weight of the polyethylene glycol backbone is in the range of from 4,000 Da to 8,000 Da, wherein the molecular weight ratio of the polyethylene glycol backbone to the polyvinyl acetate side chains is in the range of from 1:1.2 to 1:2, and wherein the average number of graft sites per ethylene oxide units is in the range of from 0.2 to 0.4; (b) amylase with greater than 90% identity to the AA560 alpha amylase endogenous to Bacillus sp. DSM 12649 and including: (i) mutations at one or more of positions 9, 149, 182, 186, 202, 257, 295, 299, 323, 339 and 345; and (ii) mutations at four or more of positions 118, 183, 184, 195, 320 and 458; and (c) laundry detergent ingredients.
