Abstract:
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.

Solubility
A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the minor component. The physical state of a solution—solid, liquid, or gas—is typically the same as that of the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
In a solution, the solute particles (molecules, atoms, and/or ions)...
