A process is provided for the preparation of a granular detergent composition having a bulk density of at least 650 g/l, which comprises treating a particulate starting material in a high speed mixer/densifier, characterised in that 0.1 to 50% by weight as calculated on the granular detergent composition of a liquid surfactant composition is mixed with the starting material during this treating process, said surfactant composition comprising (a) a sodium or potassium salt of an alkyl sulphate in an amount from 5 to 40% by weight; (b) an alkoxylated nonionic surfactant in an amount from 60 to 95% by weight, (c) the balance being water in an amount from 0 to less than 20% by weight. e |
