Abstract
Abstract A stable, free-flowing particulate adjunct suitable for use in particulate detergent compositions consists essentially of a liquid, viscous liquid, oily or waxy adjunct absorbed into a granular zeolite material of a particle size distribution of between 50 to 500 μm and having a bulk density of about 450 to 600 g/l. Suitable adjuncts are nonionic surfactants, silicones, waxes and hydrocarbons, fabric softening compounds and perfumes. Use of said particulate free-flowing adjuncts in particulate detergent compositions is also disclosed.
