TITANIUM DIOXIDE

Inert earth mineral used as a thickening, whitening, lubricating, and sunscreen ingredient in cosmetics. It protects skin from UVA and UVB radiation and is considered to have no risk of skin sensitivity. Because of its gentleness, titanium dioxide is an excellent sunscreen active for use on sensitive, redness-prone skin. ItŠ—Ès also great for use around the eyes, as it is highly unlikely to cause stinging.Titanium dioxide is typically micronized and coated for use in cosmetics products. The micronizing makes this somewhat heavy-feeling ingredient easier to spread on skin, plus a bit more cosmetically elegant. Micronized titanium dioxide also is much more stable and can provide better sun protection than non-micronized titanium dioxide. Micronized titanium dioxide does not penetrate skin so thereŠ—Ès no need to be concerned about it getting into your body. Even when titanium dioxide nanoparticles are used, the molecular size of the substance used to coat the nanoparticles is large enough to prevent them from penetrating beyond the uppermost layers of skin. This means youŠ—Ère getting the sun protection titanium dioxide provides without any risk of it causing harm to skin or your body.The coating process improves application, enhances sun protection, and also prevents the titanium dioxide from interacting with other ingredients in the presence of sunlight, thus enhancing its stability. It not only makes this ingredient much more pleasant to use for sunscreen, but also improves efficacy and eliminates safety concerns. Common examples of ingredients used to coat titanium dioxide are alumina, dimethicone, silica, and trimethoxy capryl silane.Titanium dioxide as used in sunscreens is commonly modified with other ingredients to ensure efficacy and stability. Examples of what are known as surface modifier ingredients used for titanium dioxide include stearic acid, isostearic acid, polyhydroxystearic acid, and dimethicone/methicone copolymer.Some websites and doctors maintain that titanium dioxide is inferior to zinc oxide, another mineral sunscreen whose core characteristics are similar to those of titanium dioxide. The reality is titanium dioxide is a great broad-spectrum SPF ingredient and is widely used in all manner of sun-protection products. What gets confusing for some consumers is trying to decipher research that ranks sunscreen ingredients by a UV spectrum graph. By most standards, broad-spectrum coverage for any sunscreen ingredient is defined as one that surpasses 360 nanometers (abbreviated as Š—“nm,Š—
