Development of a High Active Surfactant and High Soluble Granular Detergent by Secondary Alkyl Sulfate

Abstract

This paper discusses a process for making a granular detergent with a high content of active surfactant and favorable solubility by using various ingredients. This process contains three steps to develop the high active surfactant and soluble granular detergent. The first step was to grind (de-agglomerate) secondary alkyl sulfate (SAS) particles with inorganic material such as silica powder in a high shear mixer. After that, the ground SAS powders were agglomerated with a nonionic surfactant to produce granular detergent particles. These agglomerates were coated with inorganic materials (zeolite or silica). The coated agglomerates provided a significantly improved solubility of the granular detergent as well as providing high active surfactant and better physical properties (e.g., higher bulk density, better flow ability, etc.). In this study, the feasibility to make better performance of granular detergent by using SAS particles was discussed.
