WebbMany powders need to be added slowly enough that they have time to be wetted and incorporated into the liquid. Some hydrating thickeners, such as cellulosic polymers, need to be added quickly, while the fluid is still low-viscosity and turbulent to aid the addi- tion and dispersion of the powder. WebbThe concept of powdered solutions can be used to formulate liquid medications in dry, nonadherent, free-flowing, and readily compressible powders. The technique is based on …
