Butyloctyl Salicylate is a branched alkyl ester of salicylic acid. In sunscreens and leave-on oils it is an oil-phase ester, not salicylic acid and not a water-soluble salicylate salt. This grade is a colorless to pale yellow liquid that mixes into oils.

Sunscreen oils and anhydrous bases continue to specify this INCI when a liquid salicylate ester is used to carry oil-soluble filters. Cosmetic-grade Butyloctyl Salicylate remains a bulk ester when the assay is on the COA.
