Product Description
Octocrylene UV Absorbers Octocrilene CAS 6197-30-4
Octocrylene is an organic compound used as an ingredient in sunscreens and cosmetics. It is an ester formed by the condensation of a diphenylcyanoacrylate with 2-ethylhexanol. It is a viscous, oily liquid that is clear and colorless.
The extended conjugation of the acrylate portion of the molecule absorbs UVB and short-wave UVA (ultraviolet) rays with wavelengths from 280 to 320nm, protecting the skin from direct DNA damage. The ethylhexanol portion is a fatty alcohol, adding emollient and oil-like (water resistant) properties.
This organic compound can penetrate into the skin where it acts as a photosensitizer. This results in an increased production of free radicals under illumination. Free radicals are known to induce indirect DNA damage, and an increased concentration of free radicals might have contributed to the increased incidence of malignant melanoma in sunscreen-users compared to non-users (see Epidemiology of malignant melanoma)[weaselwords]. The only evidence gathered to date of a relationship between sunscreen use and malignant melanoma is correlational, but has not established a causal relationship.

Application
Octocrylene is used as an ingredient in sunscreen and other cosmetics. It can absorb UVA and UVB (absorption range 250-360nm, can block all UVB and part of UVA), which is a new generation of sunscreen agents.
1. UV absorber: Octocrylene has the ability to absorb UVA and UVB rays, and can be used in sunscreen products to help protect the skin from UV radiation. It can effectively reduce the damage of ultraviolet rays to the skin and prevent sunburn, sun spots and other skin problems related to ultraviolet rays.
2. Enhanced stability: Octocrylene can also enhance the stability of other UV absorbers and reduce their decomposition rate under sunlight exposure. This makes it one of the commonly used formulation ingredients in cosmetics and sun care products.
3. Mildness: Compared with some other UV absorbers, Octocrylene is milder and less likely to cause skin allergies or irritations. This makes it suitable for all skin types, including sensitive skin.
