    摘要: A free-flowing solid laundry detergent composition including: (a) detersive surfactant; (b) essentially free from zeolite builder; (c) essentially free from phosphate builder; and (d) optionally, essentially free from silicate salt; wherein the composition has a reserve alkalinity to pH 7.5 of less than 15, and wherein upon dilution in de-ionised water to form a wash liquor at 10° C. temperature and at 1 g/L concentration has a pH profile such that: (i) 3 minutes after contact with water, the pH of the wash liquor is greater than 10; (ii) 10 mins after contact with water, the pH of the wash liquor is less than 9.5; (iii) 20 mins after contact with water, the pH of the wash liquor is less than 9.0; and (iv) optionally, wherein, the equilibrium pH of the wash liquor is in the range of from above 7.0 to 8.5.
