Particle size distribution, color enhancement and uniformity are critical for cosmetic powders and one of the most common techniques used to achieve it is micronization through jet milling.
Milling is one of the most common techniques to help break down large particles to finer ones, which is used for formulations of different cosmetic products. The pin mill and hammer mill is a mechanical process used for gross milling of large particles greater than 1mm, crushing them into small powder form, usually below 100 microns.
