Abstract (en)

[origin: WO9710321A1] The 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.
