FAQ

What is Avobenzone (CAS: 70356-09-1)?

Avobenzone (CAS: 70356-09-1) is a chemical compound with the formula C19H16O4. It is a yellow crystalline solid commonly used as a UV absorber in sunscreens. Avobenzone provides broad-spectrum protection against UVA and UVB rays by absorbing harmful solar radiation. It is a substituted benzophenone derivative known for its photostability and ability to filter both UV-A and UV-B wavelengths.

What are the main uses of Avobenzone (CAS: 70356-09-1)?

Avobenzone (CAS: 70356-09-1) is primarily used in sunscreens as a UV filter to protect against sun damage. It is also found in topical medications for skin conditions and in cosmetic products. Avobenzone's ability to absorb UV radiation makes it valuable in skincare formulations. Additionally, it is used in research for studying photoprotective agents and in industrial applications for developing UV-blocking materials.

Is Avobenzone (CAS: 70356-09-1) safe?

Avobenzone (CAS: 70356-09-1) is generally considered safe when used as directed in approved products. It is approved by the FDA and EPA for cosmetic use. However, prolonged exposure to sunlight may cause photodegradation, leading to potential skin irritation. Safety precautions include avoiding direct skin contact during handling and following guidelines for proper storage. Avobenzone is not classified as a mutagen or carcinogen but should be used with care in industrial settings.

How should Avobenzone (CAS: 70356-09-1) be stored?

Avobenzone (CAS: 70356-09-1) should be stored in a cool, dry place away from direct light. It is best kept at 15-25°C (59-77°F) with low humidity. Use airtight, light-resistant containers to maintain stability and prevent degradation. Avoid exposure to heat or light to ensure product integrity. Proper storage is crucial to preserve its UV-absorbing properties and ensure safety.
