Ethylhexyl triazone

Ethylhexyl Triazone is an organic compound widely used in the formulation of sunscreen products due to its ability to absorb ultraviolet (UV) radiation, particularly in the UVB range. It is known for its high photostability and ability to protect the skin from the harmful effects of prolonged sun exposure, which can lead to conditions such as sunburn, photoaging, and an increased risk of skin cancer. Ethylhexyl Triazone functions by absorbing UV light and converting it into a less harmful form of energy, such as heat, thereby preventing it from penetrating the skin.

Chemical Properties

Ethylhexyl Triazone, chemically known as 2,4,6-Trianilino-(p-carbo-2'-ethylhexyl-1'-oxy)-1,3,5-triazine, is characterized by its high UVB absorption capabilities. It has a molecular formula of C48H66N6O6 and a molecular weight of 823.07 g/mol. This compound is oil-soluble, making it an ideal ingredient for sunscreen formulations that require water resistance and long-lasting protection.

Usage in Sunscreen

In sunscreen products, Ethylhexyl Triazone is often combined with other UV filters to achieve broad-spectrum protection against both UVA and UVB rays. Its high efficacy as a UVB filter allows for its use in products with high sun protection factor (SPF) ratings. Due to its photostability, it does not degrade easily in sunlight, maintaining the sunscreen's effectiveness over time.

Safety and Regulation

The safety of Ethylhexyl Triazone has been evaluated by various regulatory bodies around the world. In the European Union, it is approved for use in sunscreens and other cosmetics at concentrations of up to 5%, as per the regulation laid out by the European Commission. Studies have shown that Ethylhexyl Triazone is well-tolerated by the skin and does not pose significant risks of irritation or sensitization when used as directed.

Environmental Impact

Concerns have been raised about the environmental impact of chemical sunscreens, including Ethylhexyl Triazone, particularly regarding their potential effects on marine ecosystems and coral reefs. Research is ongoing to fully understand the extent of these impacts and to develop sunscreen formulations that are both effective and environmentally friendly.

Conclusion

Ethylhexyl Triazone is a valuable ingredient in sunscreen formulations, offering high UVB protection, photostability, and safety for human use. Ongoing research into its environmental impact is crucial to ensuring that sun protection can be achieved without compromising the health of our planet's ecosystems.
