Ethylhexyl Salicylate

Ethylhexyl Salicylate (octisalate) is a UVB sunscreen filter typically used around 3–5% (up to 5% in many regions) and is generally well tolerated, with low rates of irritation in standard safety testing. However, in very reactive or eczematous skin, sunscreen filters and their solvent systems can still trigger stinging or dermatitis, so it is not “inert” even if true allergy is uncommon. I rate it as gentle overall but with a small, real risk of irritation in compromised skin. Safety Notes: Ethylhexyl Salicylate (octisalate) is a UVB filter used primarily in leave-on sunscreens and daily moisturizers with SPF; at the low end it appears as a minor solubilizer/secondary UVB booster in low-SPF facial lotions and hybrid makeup-SPF products around ~0.1–1%. In high-SPF OTC sunscreen lotions/sprays/sticks, it is commonly used near its regulatory maximum to boost UVB performance and improve aesthetics, with real-world consumer products reaching 5% (the U.S. OTC monograph maximum); rinse-off products rarely use it, and when present are typically at trace-to-low levels for incidental UV benefits rather than primary protection.
