PRODUCTION OF ANIONIC SURFACTANT GRANULES BY IN SITU NEUTRALISATION

摘要

A process for producing granules of anionic surfactant, preferably PAS by in situ neutralisation of a precursor acid to form the surfactant, heating the surfactant to a temperature in excess of 130 ~C and subsequently cooling the surfactant to provide surfactant granules is disclosed. Detergent compositio ns containing such granules are also disclosed.
