Tridecyl Salicylate

Tridecyl Salicylate is an ester of salicylic acid used mainly as an emollient/fragrance component and does not function as an exfoliating BHA at typical cosmetic use levels (generally low). As a high–molecular weight, lipophilic ester, it has low water solubility and limited bioavailability, so routine irritation potential is low; however, because it is a salicylate derivative and can be present in fragranced formulas, a small risk of irritation/sensitization exists in highly reactive or eczema-prone patients. Safety Notes: Tridecyl Salicylate is most commonly encountered as a fragrance/fixative component or emollient ester, where it appears at trace-to-low levels in leave-on skincare and haircare (often ~0.01–0.3%) and sometimes up to ~1% when used to support sensory slip. In consumer-available OTC products positioned as perfumed body lotions, oils, and some specialty fragrance-forward formulations, it can be used at several percent as part of the oil/fragrance phase, with upper market observations around ~3–5% (higher would typically be limited by odor profile, cost, and overall perfume load rather than a specific global regulatory cap). Leave-on products generally sit lower than rinse-off due to cumulative fragrance exposure considerations, but both formats can span the stated range.
