Dioxybenzone

Dioxybenzone is a sunscreen ingredient that absorbs ultraviolet (UV) radiation. It is also known as benzophenone-8, and is used in many sunscreen products to protect the skin from harmful UV rays.

Chemical Properties

Dioxybenzone is a derivative of benzophenone, and has the chemical formula C14H12O3. It is a pale yellow crystalline solid that is soluble in alcohol and insoluble in water.

Uses

The primary use of dioxybenzone is as a UV absorber in sunscreen products. It absorbs UV radiation and converts it into less harmful heat, thereby protecting the skin from damage. It is also used in some cosmetics and personal care products for its UV protection properties.

Safety

The safety of dioxybenzone has been evaluated by the Food and Drug Administration (FDA) and the European Union (EU). Both organizations have approved its use in sunscreen products, but with certain restrictions. The FDA allows a maximum concentration of 3% in sunscreen products, while the EU allows a maximum concentration of 6%.

Environmental Impact

There is some concern about the environmental impact of dioxybenzone. Studies have shown that it can be harmful to coral reefs, and some regions have banned the use of sunscreens containing dioxybenzone in an effort to protect these ecosystems.
