ABSTRACT:
Low bulk density, soda ash-based, nonphosphate laundry detergents are prepared by (a) loading nonaqueous liquid surfactant onto substantially anhydrous, hydratable soda ash particles, (b) turbulently dispersing the surfactant-loaded particles into an inert gaseous medium while wetting the dispersed particles with an atomized stream of dilute aqueous sodium silicate or with separate atomized streams of water and concentrated aqueous sodium silicate, and (c) recovering the resultant particulate detergent. Preferably, natural soda ash is used in the process, and both nonionic and anionic surfactants are loaded onto the soda ash, in that order.
