Detergent powders and process for preparing them.

摘要

The dispensing properties of detergent compositions having a bulk density of 650-1100 kg/m<3> and comprising anionic and/or nonionic surfactants, and builder material, may be substantially improved by including in the compositions from 5 to 30% by weight of sodium carbonate and/or -bicarbonate and/or -sesquicarbonate, and from 1 to 15% by weight of particulate citric acid, whereby more than 80% by weight of the citric acid has a particle size which is in the range of from 350 to 1500 <0>m.
