SPRAY-DRIED BASE DETERGENT PARTICLE GIVING RISE TO A LOW PH IN THE WASH

The present invention relates to a spray-dried base detergent particle, wherein the base detergent particle comprises (by weight of the base detergent particle): (a) from 4wt% to 35wt% alkyl benzene sulphonate; (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 1wt% to 10wt% organicacid; and (g) from 1wt% to 10wt% magnesium sulphate, wherein the base detergent particle is a spray-dried particle, wherein the base detergent particle at 1wt% dilution in deionized water at 20 DEG C, has an equilibrium pH of 8.5 or less. 本发明涉及一种喷雾干燥的基础洗涤剂颗粒，其中基础洗涤剂颗粒包含(按基础洗涤剂颗粒的重量计)：(a)4重量％至35重量％的烷基苯磺酸盐；(b)0重量％至8重量％的沸石助洗剂；(c)0重量％至4重量％的磷酸盐助洗剂；(d)0重量％至8重量％的碳酸钠；(e)0重量％至8重量％的硅酸钠；(f)1重量％至10重量％的有机酸；以及(g)1重量％至10重量％的硫酸镁，其中基础洗涤剂颗粒为喷雾干燥的颗粒，其中在20℃下在去离子水中以1重量％稀释的基础洗涤剂颗粒具有8.5或更低的平衡pH。
