Harm score: 4 (Slightly harmful chemistry)
Ethylhexyl methoxycinnamate, also known by its other names as ethylhexyl methoxycinnamate, octyl methoxycinnamate, OMC, octyl methoxycinnamate or octinoxate, is a chemical quite commonly used in cosmetic and dermatological products. Its primary function is to act as a protective factor against ultraviolet radiation, making it an indispensable ingredient in many sunscreens, makeups and lip balms.
This substance can be found in shampoos, shower gels, body lotions, but also in decorative cosmetics. It contributes to the longevity and colour fastness of make-up. Ethylhexyl methoxycinnamate is popular in cosmetics for its ability to absorb a wide spectrum of UVB radiation, which prevents premature skin ageing and the formation of pigment spots. It should be noted, however, that despite its wide applicability, this substance has become the subject of debate about its potential negative effects on the environment, particularly on coral reefs. Indeed, some studies suggest that ethylhexyl methoxycinnamate may damage the DNA of corals and thus contribute to their bleaching. Therefore, in some countries, such as Hawaii, its use in sunscreens is restricted.
