Organic ultraviolet filter

Organic ultraviolet filters are a class of organic molecules used primarily as active ingredients in sunscreens and personal care products to protect skin and materials from the harmful effects of solar ultraviolet (UV) radiation[1][3][4]. These compounds absorb UV-A and UV-B light via their conjugated double bonds or aromatic ring structures, which enable electronic transitions that dissipate absorbed energy as heat[1][2][3]. Structural classes include benzophenones, cinnamates, benzotriazoles, salicylates, and camphor derivatives, among others[1][3][8]. Organic UV filters are tailored for different applications by modifying their chemical moieties, enhancing photostability, or combining multiple filters for broad-spectrum protection[1][4]. Though essential for sun protection, concerns exist regarding their photostability, the toxicity of breakdown products, potential skin sensitivity, and environmental persistence[4][5].
