PRODUCTION OF ANIONIC SURFACTANT GRANULES, SUCH SURFACTANT AND DETERGENT CONTAINING THEM

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 to provide surfactant granules is disclosed. Detergent compositions containing such granules are also disclosed.
