Ethylhexyl Methoxycinnamate

Description

Ethylhexyl Methoxycinnamate, also known as Octinoxate, is a widely used organic compound in sunscreen formulations and cosmetic products. This synthetic UV filter primarily protects against UVB rays, which are responsible for sunburn and play a significant role in photoaging and skin cancer development. Its chemical structure allows it to absorb UV radiation and convert it into less harmful forms of energy, typically heat.

With a molecular weight of 290.4 g/mol, Ethylhexyl Methoxycinnamate is an oil-soluble ingredient that enhances the texture and spreadability of sunscreen products. It is often combined with other UV filters to achieve broad-spectrum protection. The ingredient has a maximum allowed concentration of 7.5% in the United States and 10% in the European Union.

While effective, Ethylhexyl Methoxycinnamate has raised some environmental concerns due to its potential impact on coral reefs. Additionally, some studies suggest it may have weak estrogenic effects, though the clinical significance remains debated. Despite these concerns, it remains FDA-approved and is considered safe for human use when applied as directed. Ongoing research continues to evaluate its long-term effects and potential alternatives in sunscreen formulations.
