Octinoxate

Octinoxate, also known as ethylhexyl methoxycinnamate, is an organic compound used as a primary ingredient in many sunscreens. It functions as a UV-B filter, absorbing ultraviolet radiation from the sun and converting it into less harmful heat. This absorption helps to protect the skin from sunburn and long-term damage caused by UV exposure. Octinoxate is a colorless to pale yellow liquid that is lipophilic, meaning it dissolves in oils and fats, which aids in its formulation into cosmetic and skincare products. It is widely used globally due to its effectiveness and affordability.

The use of octinoxate in sunscreens has been a subject of scientific research and public discussion. While generally considered safe and effective for its intended use, some concerns have been raised regarding its potential impact on aquatic ecosystems, particularly coral reefs, and its possible endocrine-disrupting properties. Regulatory bodies in various countries, such as the U.S. Food and Drug Administration (FDA) and the European Chemicals Agency (ECHA), have reviewed and continue to assess the safety of octinoxate. Consequently, some regions have implemented restrictions on its use, especially in marine environments. Formulators of sunscreens often consider alternative UV filters to address these concerns and meet evolving consumer preferences.
