Octocrylene is an organic compound that belongs to a class of chemicals known as cinnamates. It is an ester formed by the condensation of 2-ethylhexyl cyanoacetate with benzophenone. It helps protect the skin against UV radiation and is used as an additive ingredient in skin care products such as sunscreens and other cosmetics.
The Food and Drug Administration (FDA) and European Scientific Committee on Consumer Safety (SCCS) has approved the use of Octocrylene in sunscreen products and has found it safe for use in concentrations up to 10%.

Octocrylene is a popular ingredient in many sunscreens and skin care products. It is most often used as a UV filter or absorber to protect the skin from the sun’s dangerous ultraviolet (UV) rays. Some of the main uses of octocrylene are as follows:
Q. Is Octocrylene safe in sunscreen?
Octocrylene is generally considered safe for use in sunscreen products when used within the approved concentration limits and as directed. However, some individuals may develop sensitivity or allergy to octocrylene.
Q. Is Octocrylene safe for coral reefs?
Octocrylene is suspected of being harmful to marine life, especially corals. It is not very biodegradable and can accumulate in coral reefs and act as a metabolic toxicant, potentially decreasing their resiliency to climate change.
Q. Does Octocrylene cause acne?
Octocrylene as such is not found to cause acne. However, other elements of the sunscreen may trigger breakouts in acne-prone skin.
Q. Does Octocrylene cause cancer?
Some studies have suggested that Octocrylene can breakdown into benzophenone, which is a suspected carcinogen.
Q. Is Octocrylene safe during pregnancy?
There is evidence that Octocrylene is responsible for reproductive toxicity. It is thus advised to avoid products containing Octocrylene during pregnancy.
Q. What does octocrylene do in sunscreen?
Octocrylene is a UV filter or absorber and helps in protecting the skin from the harmful effects of the sun’s ultraviolet (UV) radiation by absorbing mainly UVB radiation and short UVA wavelengths.
