Introduction to Benzophenone-3
Benzophenone-3, also known as oxybenzone, is a synthetic organic compound with the chemical formula C13H10O. It is a widely used sunscreen agent due to its effectiveness in absorbing ultraviolet (UV) radiation. This article aims to provide a comprehensive guide to benzophenone-3, covering its various aspects to help readers understand its importance and potential risks.
History and Discovery
Benzophenone-3 was first synthesized in 1870 by the German chemist August Wilhelm von Hofmann. Initially, it was used as a precursor for the synthesis of other chemicals. However, its sunscreen properties were discovered in the 1970s, leading to its widespread use in sunscreens and other cosmetic products. Over the years, benzophenone-3 has become one of the most commonly used sunscreen agents globally.
Chemical Properties
Benzophenone-3 is a white to pale yellow crystalline solid with a melting point of approximately 54-55°C. It is soluble in organic solvents such as acetone, ethanol, and chloroform but is sparingly soluble in water. The compound has a molecular weight of 182.23 g/mol and a melting point of 54-55°C. Its chemical structure consists of a benzene ring with a ketone group attached to one of the carbon atoms.
Applications
The primary application of benzophenone-3 is as a sunscreen agent. It is used in a wide range of cosmetic products, including sunscreens, moisturizers, lip balms, and lotions. Benzophenone-3 helps protect the skin from harmful UV radiation, reducing the risk of skin damage and skin cancer. Additionally, it is used in pharmaceuticals, food additives, and as a stabilizer in plastics and rubber.
Environmental Impact
While benzophenone-3 is effective in protecting skin from UV radiation, it has raised concerns regarding its environmental impact. Studies have shown that benzophenone-3 can be found in aquatic environments, where it has been linked to the disruption of endocrine systems in marine organisms. Its persistence in the environment and potential for bioaccumulation have led to concerns about its long-term effects on ecosystems.
Safety Concerns
Benzophenone-3 has been the subject of safety concerns due to its potential to cause allergic reactions in some individuals. Additionally, research has suggested that it may contribute to the development of hormone-related disorders, although more studies are needed to establish a definitive link. Despite these concerns, benzophenone-3 remains a widely used sunscreen agent due to its effectiveness in protecting against UV radiation.
Regulatory Aspects
The use of benzophenone-3 in cosmetic products is regulated by various authorities around the world. In the United States, the Food and Drug Administration (FDA) has approved its use in sunscreens, but it has also been the subject of ongoing review due to safety concerns. Similarly, the European Union has set limits on the concentration of benzophenone-3 in sunscreens and other cosmetic products.
Conclusion
Unveiling the Mystery of Benzophenone-3 CAS 131-57-7: A Comprehensive Guide provides a detailed overview of this widely used chemical compound. From its historical discovery to its current applications, environmental impact, safety concerns, and regulatory aspects, this guide offers a thorough understanding of benzophenone-3. While the compound has proven to be effective in protecting against UV radiation, it is crucial to continue monitoring its environmental and health impacts to ensure its safe and responsible use.
