Sunscreen products contain particulates to protect the skin from UVA and UVB rays. These particulates are classified as either chemicals or minerals. Chemical particulates are harmful to your health and the environment; they are endocrine disruptors, carcinogens or mutagens. Mineral-based sunscreens, on the other hand, are natural and biodegradable. The most widely used minerals are zinc oxide and titanium oxide.
Titanium dioxide has been used for a long time in paint, plastics, ceramics and dentures to obtain an opaque-white colour. It has also been used in many natural cosmetics such as foundation, for example, to ensure even skin coverage of imperfections. It is also found in soap, lipstick or cosmetics to reduce the signs of ageing. It is also often used alone as a white powder that covers surfaces well.
In addition to its pigment properties, titanium dioxide is well used by the cosmetic industry as a UV filter. It forms a stable physical barrier against UVB and to a lesser extent, against UVA. Chemically inert, highly stable and non-irritating to the skin, titanium dioxide has antimicrobial properties and does not present any possibility of allergic reaction.
In the form of a fine powder titanium dioxide poses no danger to the environment. However, nanoparticle use of titanium dioxide is still being tested. Since their effects on our health and the environment’s health are yet unknown, we do not use nanoparticulates in our products.
