Description of High quality CAS 131-53-3 Bp-8/ UV-24 /Benzophenone-8
Benzophenone-8 (dioxybenzone) is an FDA-approved sunscreen chemical with uVA-absorption capabilities. It also can protect product degradation arising from uV-light exposure. It has an approved usage level of 3 percent in the united States.
Dioxybenzone is a compound used in sunscreen formulations to block out UVB and UVA harmful rays. Broad-spectrum sunscreens often contain a number of chemical ingredients that absorb UVA and UVB radiation. Many sunscreens contain UVA-absorbing avobenzone or a benzophenone (such as dioxybenzone, oxybenzone, or sulisobenzone), in addition to UVB-absorbing chemical ingredients (some of which also contribute to UVA protection)
