Abstract

The present invention relates to a process for preparing of a particulate, free flowing detergent particle by a slurry making and spray drying technique. In particular it relates to the process for preparing a slurry with lower alkalinity for the production of spray dried laundry detergent particle. It is thus an object of the present invention to provide a process for preparing a detergent solution for a spray-dried detergent particle which provides for incorporating higher levels of the detersive surfactant whilst providing good powder properties. The present inventors have found that a spray dried detergent particle prepared from a slurry with high detersive surfactant content in presence of an in-situ formed silicate and/or a disilicate salt of alkaline earth metal, formed by reacting an alkali metal silicate with an alkaline earth metal salt, and an alkali metal silicate salt provides for excellent powder properties and extended shelf life without getting caked. It is also surprisingly found that the spray-dried particle provides desired pH in wash solution required for good stain removal performance without being harsh on the hands or the fabrics.
