Octyl salicylate, or 2-ethylhexyl salicylate, is an organic compound used as an ingredient in sunscreens and cosmetics to absorb UVB (ultraviolet) rays from the sun.[1] It is an ester formed by the condensation of a salicylic acid with 2-ethylhexanol. It is a colorless oily liquid with a slight floral odor.

The salicylate portion of the molecule absorbs ultraviolet light, protecting skin from the harmful effects of exposure to sunlight. The ethylhexanol portion is a fatty alcohol, adding emollient and oil-like (water resistant) properties.
