PCT No. PCT/US97/04690 Sec. 371 Date Feb. 24, 1999 Sec. 102(e) Date Feb. 24, 1999 PCT Filed Feb. 26, 1997 PCT Pub. No. WO97/32954 PCT Pub. Date Sep. 12, 1997Two processes for producing agglomerated high density detergent compositions are provided. On process comprises blending secondary (2,3) alkyl sulfate with a detergency builder to form a homogeneous powder mixture which is agglomerated with a surfactant paste mixture comprising C10-20 linear alkylbenzene sulfonates, C10-20 alkyl sulfates, C10-18 alkyl ethoxy sulfates having from about 1 to about 7 ethoxy groups, alcohol ethoxylates and polyethylene glycol and drying the agglomerates. Another process comprises blending secondary (2,3) alkyl sulfate with a detergency builder to form a homogeneous powder mixture which is agglomerated with a liquid acid precursor of C10-20 linear alkylbenzene sulfonate so as to form an agglomerated detergent composition which has a density of at least about 650 g/l.
