Abstract
A particulate free-flowing laundry detergent composition comprises at least two different granular components: a granular component containing anionic surfactant, and a granular nonionic surfactant component comprising from 20 to 30 wt % of nonionic surfactant on a non-spray-dried particulate carrier material comprising sodium sesquicarbonate. The nonionic surfactant component is preferably prepared by in-situ neutralisation of sodium carbonate with a water-soluble organic acid in the presence of the nonionic surfactant, in a high- or moderate-shear mixer.
