Chemical compound

2-Ethylhexyl salicylate also known as octisalateoroctyl 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 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.

Safety[edit]

In 2020 the ECHA decided that a fish sexual development test of the chemical was necessary, because the compound may be an endocrine disruptor.^[2]

The compound was identified in a court case brought by German chemical company Symrise who claimed that the ingredient used in sunscreen did not require animal testing.

Symrise lost the appeal against a European Chemicals Agency (ECHA) decision that requires the German manufacturer to test sunscreen ingredients on animals.^[3]

The Court of Justice of the European Union (CJEU) decision applies to two formerly approved ingredients used exclusively in sunscreens — UV filter homosalate and 2-ethylhexyl salicylate.^[4][5]

In 2007 octyl salicylate and all other salicylates were found to have a good safety profile.^[6] It is often used to improve affinity and reduce photodegradation of other sunscreen ingredients (such as oxybenzone and avobenzone), and under 1% of the applied dose of octyl salicylate penetrates through the skin. Although more stable, octyl salicylate is a weak organic UVB absorber.^[7]

Octyl salicylate does not produce reactive oxygen species when exposed to sunlight. However, it does have some minor sensitization potential; with some individuals experiencing minimal to mild skin irritation.^[8]
