Effect of particle size on skin permeation and retention of piroxicam in aqueous suspension.

The effects of particle size on the skin permeation and retention of piroxicam (PXC) in an aqueous suspension were investigated. PXC particles of about 23 nm, 173 nm, and 2.1 microm in size were prepared by the cogrinding of PXC/polyvinylpyrrolidone (PVP) K12/sodium dodecyl sulfate physical mixture (mean particle size, 9.6 microm) using a vibrational rod and ball mills. Particles were stable af...

Dynamic Evolution of Droplet/Particle Size Distribution in Suspension Polymerization of Styrene

Katja Ohenoja PARTICLE SIZE DISTRIBUTION AND SUSPENSION STABILITY IN AQUEOUS SUBMICRON GRINDING OF CaCO3 AND TiO2

During the past decade submicron and nanoparticles have aroused a wide interest and gained new applications due to their high surface area and strength. Grinding with a wet stirred media mill is usually the last process step before the submicron or nanoparticles are added to an application, and the step where the final particle size distribution is achieved. Since stirred media milling is an en...
