PCT No. PCT/US96/13448 Sec. 371 Date Mar. 6, 1998 Sec. 102(e) Date Mar. 6, 1998 PCT Filed Aug. 20, 1996 PCT Pub. No. WO97/10321 PCT Pub. Date Mar. 20, 1997The present invention relates to structured surfactant compositions comprising a detergent surfactant and hydrophilic silica particulates to be used in granular detergent compositions. The preferred silica particulate is hydrophilic precipitated silica. The process for making a structured surfactant composition comprising a detergent surfactant and hydrophilic silica particulates is also included. The present invention encompasses a structured surfactant composition consisting essentially of: (a) from about 35% to about 60% of a detergent surfactant; (b) from about 1% to about 20% of hydrophylic, finely-divided silica particulate; and (c) from about 15% to about 25% moisture.
