Ethylhexyl Methoxycinnamate
Also Known As: Ethylhexyl Methoxycinnamate is also known as Octyl Methoxycinnamate, Octinoxate, and by trade names such as Eusolex 2292 and Uvinul MC80.
What Is It? Ethylhexyl Methoxycinnamate is an organic compound that serves as a UV filter. It is an ester formed from methoxycinnamic acid and 2-ethylhexanol. This compound is a clear, oil-soluble liquid that is insoluble in water.
What Makes It Different? Ethylhexyl Methoxycinnamate is primarily known for its ability to absorb UV-B rays, which are responsible for causing sunburn and contributing to skin cancer. Its effectiveness as a UV filter makes it a common ingredient in sunscreens and other cosmetic products. Additionally, it helps to maintain the stability and effectiveness of other ingredients in formulations.
Where Does It Come From? Ethylhexyl Methoxycinnamate is synthesized by combining methoxycinnamic acid with 2-ethylhexanol. This synthesis process involves olefin metathesis, a chemical reaction that rearranges the bonds of olefins (alkenes) to produce the desired compound.
Where Is It Used? This compound is widely used in sunscreens, face foundations, lip care products, and other cosmetics. It acts as a UV filter, protecting the skin from harmful UV-B rays. It is also used in products to reduce the appearance of scars and to enhance the absorption of other ingredients.
Is It Sustainable? The sustainability of Ethylhexyl Methoxycinnamate is a topic of ongoing research and debate. While it is effective in protecting the skin from UV damage, there are concerns about its environmental impact, particularly on marine ecosystems. Some studies have shown that it can contribute to coral bleaching and may have endocrine-disrupting effects on marine life.
Sustainability Issues Related to Its Production:
- Environmental Impact: The production and use of Ethylhexyl Methoxycinnamate can lead to its accumulation in water bodies, where it may harm aquatic organisms.
- Coral Bleaching: There is evidence suggesting that this compound can contribute to coral bleaching, which is a significant environmental concern.
- Endocrine Disruption: Some studies have raised concerns about the potential endocrine-disrupting effects of Ethylhexyl Methoxycinnamate on both humans and wildlife.
Efforts are being made to develop more sustainable alternatives and to improve the environmental safety of existing UV filters. However, the balance between effective sun protection and environmental impact remains a challenge.
