This leads us to discuss the difference between nanoparticle zinc oxide vs. microparticle. For sunscreen, the nanoparticles in question are zinc oxide and titanium dioxide. The products have well controlled size and surface area, which enable them to have better dispersability in the operating system. PUFA-free or low-PUFA: Polyunsaturated fatty acids, a.k.a. However, according to the International Agency for Research on Cancer, titanium oxide may be a human carcinogen.

Zinc oxide is a common ingredient found in many sunscreens that are effective in blocking ultraviolet A (UVA) rays. This makes them especially difficult for use on patients with darker skin tones. Zinc oxide nanoparticles in modern sunscreens: an analysis of potential exposure and hazard. When applied, zinc oxide–containing sunscreens appear white on the skin, so they give a translucent, almost ghost-like appearance. So, zinc oxide and titanium dioxide nanoparticles aren't absorbed through the skin into the bloodstream and, in the event that they do get into the bloodstream, via accidentally eating or inhaling the particles, say, the body's immune system can deal with them effectively(for zinc oxide at least). The Vast Majority of Research Finds Nanoparticles in Sunscreen Safe . The New Health Cycle has done extensive research to give you the answer. What are the scenarios that can… Safety evaluation (including calculation of the MoS) The data provided, and as present in the literature, indicate that ZnO nanoparticles do not penetrate through the skin. Our customers have insisted that they don't want nanoparticles in our sunscreens. Sunscreen Particle Size Matters. K.M. There is some concern that nanoparticles can soak into the skin, and be harmful when used as a daily sunscreen. The optimum formulation was found to contain nano-sized titanium dioxide as well as a mixture of both micro- and nano-sized zinc oxide particles. Tyner, A.M. Wokovich, D.E. Even though we believe that nanoparticle zinc oxide is safe and effective (all research has shown that particles in the size range used in sunscreens (>30nm) do not penetrate the skin and are completely safe to use in sunscreen creams and lotions), we've chosen to not use nano zinc oxide for a few reasons. Studies have shown that these NPs are retained on the superficial layers of the skins’ barrier layer, the stratum corneum, and solubilized zinc species from the ZnO NPs have been shown qualitatively to penetrate intact human skin. It’s unlikely that nanoparticles in sunscreen cause skin damage when energized by sunlight. A tinted formula can look more natural. So, zinc oxide and titanium dioxide nanoparticles aren't absorbed through the skin into the bloodstream and, in the event that they do get into the bloodstream, via accidentally eating or inhaling the particles, say, the body's immune system can deal with them effectively(for zinc oxide at least).

A question about zinc oxide everyone really wants to know about. Google Scholar. Here's my criteria when choosing a zinc oxide sunscreen: High-zinc: Sunscreens should contain at least 20 percent zinc oxide as the active ingredient, or 15 to 20 percent zinc oxide with 7.5 percent titanium dioxide or encapsulated octinoxate. Studies have shown that these NPs are retained on the superficial layers of the skins’ barrier layer, the stratum corneum, and solubilized zinc species from the ZnO NPs have been shown qualitatively to penetrate intact human skin.
