Description of titanium dioxide

Titanium dioxide is an inert mineral used in cosmetics as a thickening, sunscreen, and sunscreen ingredient. It protects the skin from UVA and UVB radiation and is considered risk-free for skin sensitivity. Because of its mild nature, titanium dioxide is a good sunscreen active for sensitive, red-prone skin. It is ideal for use around the eyes as it is less likely to cause stinging.

There are two main forms of commercially available titanium dioxide: anatase and rutile. The rutile form is commonly used in sunscreens because of its excellent ability to handle UV rays and its stability in the presence of UV rays. The anatase form is commonly used in other types of products, such as paint. Another advantage of the rutile form is its UVA protection range of over 400 nanometers, which is the upper limit of UVA.

Titanium dioxide is commonly micronized and coated for use in cosmetics. Micronization makes this somewhat heavy ingredient easier to apply to the skin and more elegant in beauty. Micronized titanium dioxide is more stable than non-micronized titanium dioxide and can provide better sun protection.

Micronized titanium dioxide does not penetrate the skin, so there is no need to worry about it entering your body. Even with the use of titanium dioxide nanoparticles, the molecular size of the substance used to coat the nanoparticles is large enough to prevent them from penetrating beyond the uppermost layer of the skin. This means that you get the sun protection provided by titanium dioxide without causing harm to the skin or body.The coating process improves application, enhances sun protection, and prevents the titanium dioxide from interacting with other ingredients in the sun, thereby enhancing its stability. Not only does it make this ingredient more suitable for use in sunscreens, but it also improves efficacy and eliminates safety concerns. Common examples of ingredients used to coat titanium dioxide are alumina, polydimethylsiloxane, silica, and trimethoxyoctylsilane.

Titanium dioxide used in sunscreens is often modified with other ingredients to ensure efficacy and stability. Examples of the surface modifier component for titanium dioxide include stearic acid, isostearic acid, polyhydroxystearic acid and polydimethylsiloxane/polymethylsiloxane copolymer.

Some sites argue that titanium dioxide is inferior to zinc oxide, another mineral sunscreen ingredient with similar core properties. In fact, titanium dioxide is a good broad-spectrum SPF ingredient and is widely used in various sunscreen products. What confuses some consumers is the attempt to decipher studies that rank sun protection ingredients by UV spectrum.By most standards, broad-spectrum coverage of sunscreen ingredients is defined as more than 360 nanometers (abbreviated as "nm"-the way the sun's rays are measured). Titanium dioxide is beyond this protection, but based on the research you read, it is either comparable to or slightly inferior to zinc oxide in performance.

It is true that titanium dioxide does not rank as well as zinc oxide for UVA protection, but ultimately the difference between the two is small (think 10 years and 10 years and 3 months). This is not easily understood in terms of other factors that affect the performance of sunscreen actives, such as the base formulation, so many people, including some dermatologists, believe that zinc oxide is superior to titanium dioxide for UVA protection.Titanium dioxide is formulated to provide excellent UVA protection. Its peak UVA protection is lower than that of zinc oxide, but both provide protection over the entire UVA range for the same amount of time.

Titanium dioxide is in the form of a white powder and is sometimes used in cosmetics to adjust the color to a lighter shade. This is also the reason why it can produce white castings.
