Production of anionic surfactant granules by in situ neutralisation |
摘要 |
In process for producing detergent particles, an acid precursor of an anionic surfactant and a neutralizing agent are fed into a horizontal thin-film evaporator/drier where they are neutralized, granulated and dried. The neutralizing agent is present in an amount equal to or in excess that required for stoichiometric neutralization and has a D50 mean particle size of less than 40 mum.
