Oxybenzone (Benzophenone-3)
organic sunscreen That can block UVB light in the wavelength range of 270-320nm and block UVA light in the short wavelength range of 320-342nm. It can work well with other sunscreens , especially Avobenzone, which Oxybenzone will help increase stability.
Organic sunscreen that can block UVB light in the wavelength range of 270-320nm and UVA light in the short wavelength range of 320-342nm can work well with other sunscreens, especially Avobenzone, which Oxybenzone will increase stability.

SPF calculation: 1% Oxybenzone = SPF 1.5
To help increase the stability of Avobenzone, use a 1:1 or 2:1 ratio (e.g. 5-10% Oxybenzone to 5% Avobenzone).
FDA rules for using Oxybenzone in any type of cosmetics
Europe (including Thailand): not more than 10%
Japan: no more than 5%
USA: no more than 6%
