Avobenzone

Description:
Avobenzone, with the CAS number 70356-09-1, is a chemical compound primarily used as a sunscreen agent due to its ability to absorb the full spectrum of UVA rays, providing effective protection against skin damage and photoaging. It is a lipophilic molecule, which means it is soluble in oils and fats, making it suitable for incorporation into various cosmetic formulations. Avobenzone is known for its stability under UV light compared to other sunscreen agents, although it can degrade when exposed to sunlight over time unless stabilized with other ingredients. Its chemical structure features a conjugated system that allows it to absorb UV radiation effectively. In formulations, it is often combined with other UV filters to enhance overall sun protection. Avobenzone is generally considered safe for topical use, but some individuals may experience skin sensitivity or allergic reactions. Regulatory bodies, including the FDA, have approved its use in sunscreens, making it a popular choice in both cosmetic and dermatological products.
