Granular surfactants and method of manufacturing

For example, simultaneously subjected to drying and granulation by spraying all or part of the surfactant in water or a fluidized bed in which the slurry was allowed solution or dispersed and dissolved in hot water introduced hot air, obtained by the above process granular surfactant obtained particles were classified to remove the low-particle-diameter particles. Typically, the weight ratio of the particle diameter of 0.1mm or less particle is not more than 2.0 wt%, median diameter is not less than 0.17 mm. The granular surfactant is easy to manufacture, excellent in solubility in water, dusting less flowable.
