Title (EN) PRODUCTION OF ANIONIC SURFACTANT GRANULES BY IN SITU NEUTRALISATION
(FR) PRODUCTION DE GRANULES DE TENSIOACTIF ANIONIQUE PAR NEUTRALISATION IN SITU
Abstract: front page image
(EN)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 compositions containing such granules are also disclosed.
(FR)Procédé de production de granules de tensioactif anionique, de préférence du sulfate d'alkyle primaire (PAS), consistant à neutraliser in situ un acide précurseur afin de former le tensioactif, à chauffer celui-ci à une température supérieure à 130° C, puis à le refroidir afin d'obtenir des granules tensioactifs. On décrit également des compositions détergentes contenant de tels granules.
