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.
Compositions tensioactives structurées qui contiennent un tensioactif de détergent et de la silice hydrophile particulaire, à utiliser dans des compositions détergentes granulaires. La silice particulaire préférée est de la silice précipitée hydrophile. Le procédé de préparation d'une composition tensioactive structurée contenant un tensioactif de détergent et de la silice hydrophile particulaire est également décrit. La présente invention concerne en outre une composition tensioactive structurée constituée essentiellement de (a) environ 35 % à environ 60 % d'un tensioactif de détergent, (b) d'environ 1 % à environ 2 % de silice particulaire fine hydrophile et (c) d'environ 15 % à environ 25 % d'humidité.
