Micronized minerals are emerging on the marketplace in natural cosmetics and sunscreens. Many companies promoting natural cosmetics are extolling the benefits of micronized minerals in their "all natural" make-up. Some cosmetic products are promoted as 100% pure micronized minerals.
But beware! There are research studies that suggest caution when considering the use of micronized mineral cosmetics.
Micronized minerals, also known as ultrafine or nanoparticles, are mineral pigments where the size of the particles has been reduced. In general, particles are classified according to size as coarse, fine or ultrafine. Micronized particles, the ultrafine or nanoparticles, are 100 times smaller than coarse particles and 25 times smaller than fine particles, according to etcgroup.org.
According to the FDA, there is no official definition of "micronized," but they refer to these particles being less than 250 nanometers, and they also regard nanoscale titanium dioxide as "micronized titanium dioxide."
