Dioxybenzone(CAS: 131-53-3)

Dioxybenzone, with the CAS number 131-53-3, is a chemical compound commonly used as a UV absorber. Its chemical formula is C13H10O4, and it is a white crystalline powder that is soluble in organic solvents. It is known for its ability to absorb ultraviolet light, particularly in the UVA range, making it useful in sunscreens and other photoprotective products.

Dioxybenzone is primarily used in sunscreens and cosmetics as a UV filter to protect the skin from harmful ultraviolet rays. It also finds applications in pharmaceuticals, industrial coatings, and research settings where UV protection is necessary. Its use in food products is limited due to regulatory concerns.

Dioxybenzone is generally considered safe when used as directed in topical products, but it may cause skin irritation or allergic reactions in some individuals. It is classified as a potential endocrine disruptor, and proper handling, including the use of protective gloves and eyewear, is recommended. Safety standards vary by application and regulatory region.

Dioxybenzone should be stored in a cool, dry, and dark place to maintain its stability and effectiveness. It is typically kept in airtight containers away from moisture and light exposure. Storage conditions should be controlled to prevent degradation, and it is advisable to store it at temperatures below 25°C for optimal preservation.
