Avobenzone is a derivative of dibenzoylmethane. It is an oil-soluble component. Avobenzone absorbs a wider range of wavelengths of ultraviolet light. It is included in many commercially available sunscreens, which are used as broad-spectrum sunscreens. Avobenzone is very sensitive to light, and in order to increase its stability and duration of action, a light stabilizer is added to the sunscreen products. The maximum absorption of avobenzone is 357 nm. Sunscreen containing avobenzone is suitable for sun protection. In addition to limiting skin exposure to the sun, the use of sunscreen can also help reduce long-term sun damage, such as premature skin aging and skin cancer.
Avobenzone is an oil soluble ingredient used in sunscreen products to absorb the full spectrum of UVA rays. It is a dibenzoylmethane derivative. Avobenzone exists in the ground state as a mixture of the enol and keto forms, favoring the chelated enol. Its ability to absorb ultraviolet light over a wider range of wavelengths than many organic sunscreen agents has led to its use in many commercial preparations marketed as "broad spectrum" sunscreens. Avobenzone has an absorption maximum of 357.
It blocks UVA I, UVA II, and UVB wavelengths, thus limiting the effects of ultraviolet light on the skin. Reduces the penetration of ultraviolet (UV) light through the epidermis by absorbing UV radiation in a specific wavelength range. The amount and wavelength of UV radiation absorbed are affected by the molecular structure of the sunscreen.
Avobezone is a synthetic UV-absorbing Chemicalbook receiver. It is a good UV-A (>320nm) type UV absorber, which can block the full range (320~400nm) of UVA and is highly effective Broad-spectrum oil-soluble UVA filter, compounded with other UVB sunscreens, can provide all UVA and UVB protection, used to prevent photo-induced skin cancer.
Avobezone is recommended to store it in a cool, dry place, sealed from outside air. We ship the product in a double sealed bag which can be resealed. Another container is recommended sealing from outside air.
