  • Patent number: 5962397
    Abstract: Disclosed are granular detergent components and processes for making these components. The processes comprise the steps of: i) forming the granular detergent component by drying an aqueous solution, the aqueous solution comprising at least 50% of a cationic surfactant, to form a powder; and then ii) densifying the powder in the presence of a detergent powder selected from the group consisting of aluminosilicate, carbonate, bicarbonate, silicate, sulphate, citrate, clay and mixtures thereof and an acid selected from the group consisting of citric, sulphuric, hydrochloric, polycarboxylic acids and mixtures thereof. This granular detergent component consists essentially of the cationic surfactant, the acid and the particulate builder and the granular detergent component has a reserve acidity of at least 1.0 g HCl/100 g.
