BENZOPHENONE-9
Description
Benzophenone-9, also known as oxybenzone, is a widely used organic compound in skincare formulations, particularly in sunscreens. This ingredient functions as a broad-spectrum UV filter, effectively absorbing both UVA and UVB radiation. Its chemical structure allows it to dissipate absorbed UV energy as heat, providing protection against sun-induced skin damage.
Benzophenone-9 is oil-soluble and typically colorless, making it easy to incorporate into various cosmetic formulations. It enhances the photostability of other UV filters and can boost the overall SPF of a product. The ingredient is often used in combination with other sunscreen agents to achieve optimal broad-spectrum protection.
While effective, benzophenone-9 has faced scrutiny due to potential environmental concerns and skin sensitization in some individuals. It has been associated with coral reef damage and can be absorbed through the skin, leading to trace amounts in the bloodstream. As a result, some regulatory bodies have restricted its use, and alternative UV filters are being explored in newer formulations. Despite these concerns, benzophenone-9 remains approved for use in many countries when formulated within specified concentration limits.
