Function:
When used in combination with certain light stabilizers, it can improve the light stability of the entire sunscreen system.
Avobenzone can absorb ultraviolet rays in the UVA band (320 – 400nm).
Application:
Due to its good UVA absorption capacity, it can effectively block the damage of long-wave ultraviolet rays to the skin and is often used in the production of broad-spectrum sunscreen products. It can be added to hair care and styling products with sunscreen function.
