Process for making detergent granules by neutralization 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 5 mu m. The present invention also encompasses free-flowing detergent compositions made with the process.
