摘要：
The present invention relates to a solid free flowing particulate laundry detergent composition comprising:
(a) anionic detersive surfactant;
(b) from 0wt% to 8wt% zeolite builder;
(c) from 0wt% to 4wt% phosphate builder;
(d) from 0wt% to 8wt% sodium carbonate;
(e) from 0wt% to 8wt% sodium silicate;
(f) from 4wt% to 20wt% organic acid; and
(g) a variant of the wild-type lipase from Thermomyces lanuginosus which has at least 90% identity for amino acid sequence SEQ ID NO:1; and which comprises T231R and/or N233R mutations;
wherein the composition comprises from 30wt% to 90wt% base detergent particle, wherein the base detergent particle comprising (by weight of the base detergent particle):
(a) from 4wt% to 35wt% anionic detersive surfactant;
(b) optionally, from 1wt% to 8wt% zeolite builder;
(c) from 0wt% to 4wt% phosphate builder;
(d) from 0wt% to 8wt% sodium carbonate;
(e) from 0wt% to 8wt% sodium silicate;
(f) from 1wt% to 10wt% organic acid; and
(g) optionally, from 1wt% to 10wt% magnesium sulphate,
wherein the composition at 1wt% dilution in deionized water at 20°C, has an equilibrium pH in the range of from 6.5 to 9.0.
