PROCESS FOR MAKING DETERGENT GRANULES BY NEUTRALISATION OF SULPHONIC ACIDS

摘要

THE PRESENT INVENTION RELATES TO A PROCESS FOR MAKING A DETERGENT PARTICLE BY NEUTRALISATION OF THE ACID FORM OF AN ANIONIC SURFACTANT IN A HIGH SHEAR MIXER BY A STOICHIOMETRIC EXCESS OF FINELY DIVIDED PARTICULATE NEUTRALISING AGENT HAVING AN AVERAGE PARTICLE SIZE OF LESS THAN 5µM. THE PRESENT INVENTION ALSO ENCOMPASSES FREE-FLOWING DETERGENT COMPOSITIONS MADE WITH THE PROCESS.
