oksibensoon

Oksibensoon, also known as oxybenzone or benzophenone-3, is an organic compound commonly used as a sunscreen ingredient. It is a white to pale yellow crystalline powder that is soluble in organic solvents but poorly soluble in water. Its primary function in sunscreens is to absorb ultraviolet (UV) radiation, specifically in the UVB and UVA II ranges. This absorption process helps to protect the skin from the damaging effects of sun exposure, such as sunburn and premature aging.

Oksibensoon is synthesized through a chemical reaction involving the Friedel-Crafts acylation of diphenyl ether. It is one of the most widely used sunscreen agents globally due to its effectiveness and cost-efficiency. Beyond its use in personal care products, oksibensoon can also be found in some plastics and coatings as a UV stabilizer.

However, oksibensoon has also been the subject of environmental and health concerns. Studies have raised questions about its potential to disrupt endocrine systems and its impact on marine ecosystems, particularly coral reefs. This has led to restrictions and bans on its use in some regions, prompting a search for alternative UV filters. Despite these concerns, it remains a common ingredient in many sunscreen formulations available in various markets.
