The dry blending procedure that gives the best results in the laboratory with the nonionic surfactant-based high density laundry powders is the following  

Combine all dry components over a 1-2 minute time period while stirring in a Brabender Visco-Corder viscosimeter/paddle mixer. 

Heat Neodol until single-phase liquid drop-wise, add warm nonionic to dry component mixture, stirring until nonionic is evenly adsorbed onto dry component beads.
