Abstract (en)

[origin: WO9919454A1] Processes for preparing high density detergent composition containing a mid-chain branched surfactant are provided. The processes involve spray drying, agglomerating, mixing, blending or a combination thereof and produce a granular and/or agglomerated detergent composition directly from mid-chain branched surfactants and other starting detergent ingredients. The mid-chain branched surfactants are mid-chain branched primary alkyl sulfate surfactants and mid-chain branched primary alkyl alkoxoxylated sulfate surfactants having an average of greather than 14.5 carbon atoms.
