Abstract

A detergent composition containing surfactants selected from anionic, cationic, nonionic, amphoteric and zwitterionic surfactants and a builder component containing 40% to 80% by weight of amorphous alkali metal silicates and 10% to 40% by weight of alkali metal carbonates in the form of a compound, with the proviso that the alkali metal carbonate content is always greater than the alkali metal silicate content, and at most 25% by weight of water, and wherein the compound does not have a homogeneous surface nor a uniform particle size distribution.
