Abstract

This invention relates to a granular, free-flowing detergent component which dissolves rapidly in water and which has a powder density of from 550 to 900 g/l, consisting of synthetic, essentially nonionic surfactants, inorganic supports, other organic washing aids, and water bound by adsorption and in hydrate form. The detergent component is produced by spray-drying, and more than 50% by weight thereof consists of droplet-like to rodlet-like particles having an average diameter of from about 0.02 to 1.5 mm, an average length of from about 0.1 to 5 mm, and a ratio of average diameter to average length of from about 1:1.2 to 1:10, optionally coated with a finely divided water-soluble or water-dispersible solid material as a fluidity improving agent.
