The dosage of the UV absorbers in sunscreen cosmetics is generally between 0.1-10%. Too much can cause allergic reactions to the skin. The usage of UV absorbers is mostly obtained through the actual sun test. In addition, the dosage varies with the absorption energy of the compound, which cannot be generalized.
Details:
Protect formulations against UV light with Spectrum’s selection of cosmetic UV absorbers used to reduce the amount of light absorbed by chromophores. These high quality UV absorbers are incorporated into cosmetic or personal care formulations and used to improve light stability of alcoholic fragrances, gels, colors, nail enamels and liquid detergents.

Sunscreen is an eternal topic in cosmetics, but it cannot exist without UV absorbers in cosmetic industry. Not only does it prevent the skin from being burned or scorching, but it is also non-toxic and harmless to the skin. With good compatibility with other cosmetics raw materials. At the same time, it must be low volatility and strong stability.
UV absorbers have the function to absorb the UV rays (UV A & UV B). The skin absorbs the chemical sunscreen molecules. The process of UV absorption occurs in the skin and is eliminated by metabolism of the human body. There is no chemical reaction, but the electrons transition in the molecule from low energy orbit to high energy orbit. Energy will release in the form of heat. Thus, it can absorb ultraviolet rays to prevent skin injury. Sunscreen is soluble in the oil phase.
