A process for making a high active granular detergent component or composition having a bulk density of at least 650 g/l which comprises the steps of: i) making a paste or liquid which comprises at least 40 % by weight of a surfactant selected from anionic and nonionic surfactants, ii) mixing said surfactant paste or liquid with a powder to form a mixture which may be in the form of either a paste of a cohesive powder; iii) forming granules by fine dispersion mixing or granulation of said mixture, optionally in the presence of an effective amount of one or more additional powders; wherein the powder used in step ii) comprises a free-flowing, premixed powder comprising from 0.5 % to 10 % by weight of a hydrophobic silica and from 75 % to 99.5 % by weight of a hygroscopic powder comprising a polymer.
