Usage
Avobenzone is a widely used chemical substance, mainly serving as a sunscreen agent in cosmetics, especially in sunscreens and personal care products. It can effectively absorb UVA radiation, providing broad-spectrum ultraviolet protection and helping to prevent photo-induced skin cancer. The following are some of the main application ways of avobenzone:
1. Cosmetic Sunscreen Agents: Due to its good UVA absorption ability, avobenzone is widely used in cosmetics such as sunscreens and lotions to enhance the sun protection effect of the products.
2. Personal Care Products: Besides cosmetics, avobenzone is also used in other personal care products, such as shampoos and body washes, to provide additional ultraviolet protection.
3. Baby Sunscreen: Because of its relative safety and effectiveness, avobenzone is also used in baby sunscreen products to protect the delicate skin of infants and young children from ultraviolet damage.
4. Daily Skincare: In daily skin care products, avobenzone can act as an ultraviolet filter to help reduce the damage of ultraviolet rays to the skin and prevent the formation of wrinkles and dark spots.
5. Decorative Cosmetics: In some decorative cosmetics, avobenzone is also used as an ultraviolet absorber to protect the products from photodegradation caused by ultraviolet rays.
When using avobenzone, attention should be paid to its stability and avoid contact with metal ions to prevent discoloration. In addition, it should be used according to the recommended dosage to ensure the safety and effectiveness of the products.
