BENZOPHENONE-3
Description
Benzophenone-3, also known as oxybenzone, is a widely used organic compound in sunscreen formulations and other personal care products. This synthetic chemical functions as a broad-spectrum UV filter, effectively absorbing both UVA and UVB radiation. Its ability to protect against a wide range of ultraviolet light makes it a valuable ingredient in sun protection formulas.
Chemically, benzophenone-3 is a aromatic ketone with the molecular formula C14H12O3. It appears as a pale yellow solid at room temperature and is soluble in most organic solvents. In sunscreens, it typically comprises 1-6% of the formulation.
While effective in UV protection, benzophenone-3 has faced scrutiny due to potential environmental and health concerns. Studies have suggested it may contribute to coral reef bleaching and disrupt endocrine function in some marine life. Additionally, there are concerns about its potential for skin absorption and allergic reactions in humans.
Due to these issues, some jurisdictions have restricted or banned its use in sunscreens. Formulators are increasingly exploring alternative UV filters to replace benzophenone-3 in sun care products, balancing efficacy with environmental and health considerations.
