Development of a novel granular detergent with an interspersion particle comprising an anionic surfactant and a polymeric polycarboxalate.
This paper discusses a process for making a novel granular detergent with an interspersion particle comprising an anionic surfactant and a polymeric polycarboxalate. This process contains three steps to develop the interspersion particles with anionic surfactant and polymeric ploycarboxalate. The first step was to form a detergent particle by spray drying of an aqueous detergent slurry comprising anionic surfactant (liner alkyl benzene sulfonate) with the different levels of polymeric polycarboxalate. In the second step, the spray-dried granules were densified and ground by a roll compacter and a grinder. The ground particles were coated by nonionic and zeolite in a vertical batch type high shear mixer (third step). In this study, the feasibility to make better performance of granular detergent was discussed.
