    摘要： The present invention relates to a process for making a particulate laundry detergent composition, wherein the process comprises the steps of: (a) contacting water, starch, acid and perfume to form a concentrated aqueous acidic mixture, wherein the concentrated acidic mixture comprises: (i) from 20wt% to 60wt% starch; (ii) from 10wt% to 50wt% acid; (ii) from 2wt% to 20wt% perfume; (iv) from 10wt% to less than 45wt% water; and wherein the concentrated acidic mixture has a pH of less than 4.5; (b) subjecting the concentrated acidic mixture to a perfume emulsification step to emulsify the perfume to form an emulsified perfume mixture in fluid form; and (c) spraying the emulsified perfume mixture in fluid form onto base detergent particles so that the emulsified perfume mixture at least partially coats the base detergent particles to form the particulate laundry detergent composition, wherein the base detergent particles comprise from 4wt% to 60wt% detersive surfactant.

    摘要： The present invention provides an effervescence composition comprising an acid source and a carbon dioxide source, wherein at least 85 % of said acid source has a particle size from 0.1 to 150 microns, preferably from 0.5 to 100 microns. The carbon dioxide source is preferably also of a small particle size. The effervescence composition is in particular useful in solid detergent compositions. The effervescence component is preferably in the form of a granule comprising at least part of the acid source and the at least part of the carbon dioxide source. The effervescence component can also be coated by a coating comprising an alkoxylated alcohol having an alkoxylation degree of at least 20.

    摘要翻译： 本发明提供了包含酸源和二氧化碳源的泡腾组合物，其中所述酸源的至少85％具有0.1至150微米，优选0.5至100微米的粒度。 二氧化碳源优选也是小粒度。 泡腾组合物特别适用于固体洗涤剂组合物。 泡腾组分优选为包含至少部分酸源和至少部分二氧化碳源的颗粒形式。 泡腾组分也可以用包含烷氧基化度至少为20的烷氧基化醇的涂料涂覆。
