Abstract (en)

[origin: WO9919453A1] A process which produces a compact granular detergent composition directly from mid-chain branched surfactants and other starting detergent ingredients is disclosed. The mid-chain branched surfactants are mid-chain branched primary alkyl sulfate surfactants and mid-chain branched primary alkyl alkoxylated sulfate surfactants having an average of greater than 14.5 carbon atoms. The process involves mixing a surfactant paste and drying detergent ingredients, spray drying the resulting slurry, compacting the spray dried granules, grinding and coating the granules to form the finished detergent product.
