Abstract

Pressed cosmetic powders made from mineral powders are widely used due to their ability to camouflage acne, rosacea, and scars; amongst many other skin discolorations. Similarly, they are popular due to their incorporation of zinc oxide which ultimately affects the features of camouflaging and sunscreen protection. In this work, three different techniques were compared: blending, hand mixing with a mortar and pestle, and dry coating using a magnetically assisted impaction coating device (MAIC). System parameters included variations of dry coating, coating percentage of silica, mixing time, and MAIC magnet to powder ratio to examine how well the nanoparticles were coated. Each powder was characterized using bulk density to determine how well the powders pack, and energy-dispersive X-ray (EDX) spectroscopy to determine the uniformity of the mixture. Preliminary results showed higher bulk density for the dry coated samples compared to the other two. EDX Spectroscopy results show that the dry coated samples also yielded more uniform samples.
