摘要：
A solid particulate laundry detergent composition including: (a) substituted cellulosic polymer including carboxymethyl substituent groups, and having a degree of substitution (DS) of at least 0.55, and having a degree of blockiness (DB) of at least 0.35, and having a DS+DB is in the range of from 1.05 to 2.00; (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.
