Octocrylene
Also Known As:
- 2-Ethylhexyl 2-cyano-3,3-diphenylprop-2-enoate
- Octocrilene
- Uvinul N-539
What is it? Octocrylene is an organic compound commonly used in sunscreens and cosmetics. It is an ester formed by the reaction of 2-ethylhexyl cyanoacetate with benzophenone. This compound is a viscous, oily liquid that is clear and colorless.
What Makes it Different? Octocrylene is known for its ability to absorb UVB and short-wave UVA rays, protecting the skin from direct DNA damage. It is photostable, meaning it maintains its effectiveness after exposure to light, and it also enhances the stability of other sunscreen ingredients. Additionally, it has emollient properties, which help to moisturize the skin.
Where Does it Come From? Octocrylene is synthesized through a chemical process involving the Knoevenagel condensation of 2-ethylhexyl cyanoacetate with benzophenone. This process is carried out in industrial settings to produce the compound in large quantities for use in various products.
Where is it Used? Octocrylene is widely used in:
- Sunscreens
- Lip balms
- Beauty balm creams
- Hair conditioners
- Anti-aging creams
Its primary function in these products is to absorb harmful UV rays, thereby preventing skin damage such as sunburn and premature aging. It also helps to improve the water resistance of these products.
Is it Sustainable? The sustainability of octocrylene is a complex issue. While it is effective in protecting the skin from UV damage, its production and use raise several environmental concerns.
Sustainability Issues Related to its Production:
- Environmental Impact: Octocrylene has been shown to accumulate in marine environments, where it can harm coral reefs and other marine life. This has led to bans on its use in certain regions, such as Palau and the United States Virgin Islands.
- Chemical Stability: Over time, octocrylene can degrade into benzophenone, a compound that has been associated with potential health risks, including endocrine disruption.
- Production Process: The industrial synthesis of octocrylene involves the use of various chemicals and energy, contributing to its environmental footprint.
In summary, while octocrylene is a valuable ingredient in many personal care products, its environmental and health impacts necessitate careful consideration and regulation.
