Method for producing non-ionic tenside granulates
摘要:
Surfactant granules are made by the process comprising the steps of (1) mixing an aqueous nonionic surfactant paste and an aqueous solution of an organic polymeric carrier; (2) simultaneously granulating and drying the mixture from step (1) in a fluidized bed to form a granulated nonionic surfactant. The surfactant granules are dust-free, flowable, storage-stable, show no tendency toward clumping and are readily soluble in cold water.
