PROCESS FOR MAKING GRANULAR DETERGENT COMPONENT

摘要

The invention relates to a process for the preparation of a granular detergent component comprising the steps of : (i) forming the granular detergent component by drying an aqueous solution of a cationic surfactant to form a powder ; (ii) optionally, densifying the powder ; wherein the granular detergent component further comprises an acid, the granular detergent component having a reserve acidity of at least 1.0 g HCl/100g, preferably at least 3.0 g HCl/100g, and more preferably at least 8.0 g HCl/100g. The invention also relates to granular detergent components having a bulk density of at least 500 g/l comprising: at least 20% by weight of cationic surfactant (preferably choline ester), and from 1% to 60% by weight of an acid, and optionally, up to 79% by weight of a detergent powder wherein the granular detergent component has a reserve acidity of at least 1.0 g HCl/100g.
