   Octocrylene is an organic compound used in sunscreens and make-up, 

an oil-soluble UV absorber with water-insoluble properties. 

Properties that contribute to the solubility of other oil-soluble solid sunscreens.

 It has the advantages of high absorption rate, non-toxicity, non-teratogenicity, 

good stability to light and heat. Oaklein belongs to the cinnamic acid class of ultraviolet absorbers,the maximum absorption wavelength of ultraviolet light is 308nm, 

and it has a strong absorption capacity for ultraviolet light (UVB) with wavelengths 

in the range of 280-320nm. Oaklein absorbs UV-B and a small amount of UV-A, and has 

a stabilising effect on the UVA sunscreen Avobenzone (Paso 1789), 

which is an FDA-approved Class I sunscreen, with a high usage rate in the US and Europe. 

The maximum permitted additive amount of Oclarin in China, the EU, Japan, the United States, 

and South Korea is 10% (calculated as a mass fraction). However, in daily sunscreen products, 

the added amount is usually 1-3%, and very few products add up to 10%. 

Octocrylene is used as a UV-A and UV-B filter for sunscreen and topical pharmaceutical preparations, and as a UV absorber for plastics, paints and dyes. Octocrylene is an organic
