    • A process for preparing a modified sodium carbonate carrier material, the process comprising the steps of: (i) preparing an aqueous solution of sodium carbonate; an effective amount of a crystal growth modifier selected from the group comprising polyacrylates, polyaspartates and polyaspartic acids; and optionally one or more anionic and/or nonionic detergent-active compounds, one or more detergency builders and/or one or more further heat-insensitive detergent components; whereby crystal growth-modified sodium carbonate is formed; (ii) drying the solution to form a dry solid carrier material; (iii) optionally incorporating into the dried solid carrier material one or more detergent components in liquid form and/or mixing the dried solid material with one or more solid detergent components. Also, a modified sodium carbonate carrier material comprising: dry inorganic solids consisting of habit modified sodium carbonate; and polyaspartic acid, or a sodium salt of polyaspartic acid, wherein the weight ratio of polyaspartic acid to the dry inorganic solids is in the ratio from 0.5:100 to 10:100.
    • 一种制备改性碳酸钠载体材料的方法,该方法包括以下步骤:(i)制备碳酸钠水溶液; 有效量的选自聚丙烯酸酯,聚天冬氨酸酯和聚天冬氨酸的晶体生长改性剂; 和任选的一种或多种阴离子和/或非离子洗涤剂活性化合物,一种或多种去污助洗剂和/或一种或多种其它热不敏感洗涤剂组分; 由此形成晶体生长改性的碳酸钠; (ii)干燥溶液以形成干固体载体材料; (iii)任选地将干燥的固体载体材料中一种或多种液体形式的洗涤剂组分和/或将干燥的固体材料与一种或多种固体洗涤剂组分混合。 另外,改性碳酸钠载体材料包括:由习惯改性的碳酸钠组成的干燥无机固体; 聚天冬氨酸或聚天冬氨酸的钠盐,其中聚天冬氨酸与干无机固体的重量比为0.5:100至10:100。
