The use of nanoparticles in mineral make up was also an attempt to improve the appearance of the product. Pulverizing the minerals to nano-size gave the cosmetics a smoother, more glowing appearance. Consumers liked the change but didn't realize there were associated health risks.
How Do You Avoid Nanopartilces?
Hundreds of personal care products already contain nano-sized ingredients, and thousands more contain ingredients that are available in nano form but don't include information about particle size on the labels, according to a Skin Deep analysis. Since nano-sized ingredients are absorbed differently into the body, they require separate safety studies. Manufacturers seem to be following the pattern they established with conventional chemical ingredients-put poorly tested chemicals into personal care products and do the science later, if at all.
When buying sunscreens that use metal oxides or mineral make up, look for products that don't use nanoparticles or "micronized" particles. "Non-Micronized" particles are larger than nanoparticles so are safer. Titanium dioxide particles can also be coated with stearic acid to further prevent interaction of the mineral with the body.
Stick with mineral make up that uses titanium dioxide in cream form rather than powder form. This prevents the particles from being absorbed through the skin or becoming airborne and getting into the lungs. If you are concerned about the health risks of nanoparticles, consider using one of the many great choices in natural and organic cosmetics that allow you to look great without risking your health.
Numerous research studies have showed the dangerous effects of nanoparticles and there is little doubt that they pose a significant health threat. A movement is underway to have the FDA regulate engineered nanoparticles much more rigorously. Until that time, consumers have to be smart shoppers.
