Octisalate
What is Octisalate?
Octisalate, chemically known as ethylhexyl salicylate, is a synthetic ester derived from salicylic acid and 2-ethylhexyl alcohol. It belongs to the salicylate class of organic compounds commonly employed in cosmetic formulations, particularly sun protection products. In skincare, it primarily functions as a UVB absorber, capturing ultraviolet B radiation in the 290-320 nm range and converting it into harmless heat energy, thereby helping to prevent sunburn and related skin damage from sun exposure. Beyond UV filtering, it can serve as a solvent for other ingredients or contribute to fragrance profiles by masking odors. Typically incorporated into lotions, creams, and sprays at levels suitable for daily or recreational use, its oil-soluble nature allows even dispersion in oil-based emulsions, enhancing product stability and spreadability without leaving a heavy residue.
