Ethylhexyl salicylate (also known as octyl salicylate or octisalate) is a chemical filter commonly found in sunscreens. It has the ability to block UVB rays.
Its texture is liquid oily and it is colorless. Furthermore, it has antibacterial properties and helps sunscreen to preserve more time.
Ethylhexyl salicylate spectrum range and stability
Octisalate belongs to salicylates group (a type of sunscreen filters) so it can absorb UVB rays.
It is a weak sunscreen filter so it is usually combined together with other sunscreen filters in the same product to enhance sun protection.
Octisalate it’s commonly present in sunscreen that contains avobenzone due to its capacity to stabilize avobenzone.
Due to the fact that salicylates are not water soluble (they can’t disolve in water), they keep their ability to still working and protecting the skin after being exposed to water or sweat.
Ethylhexyl salicylate allergies and absorption
Octyl salicylate is generally well tolerated and rare cases of allergies such as allergic contact dermatitis have been reported.
It can act as a skin penetration enhancer. Studies have reported that octisalate can be absorbed trough the skin but systemic absorption has not been reported.
Although it posses a good safety profile, further research is needed to determine if it really posses any risk as an endocrine disruptor but it shouldn’t be a concern for now.
Is octisalate reef safe?
As I’ve said before, it’s known that octisalate is not water soluble, so it does not dissolve in water and should not cause any water environmental concern.
Anyway, no studies have reported how octisalate could affect marine life so it’s not actually known.
