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.
