3,3,5-Trimethylcyclohexyl Salicylate, classified as a salicylate, is an organic compound resulting from the esterification of salicylic acid and 3,3,5-trimethylcyclohexanol, a derivative of cyclohexanol. The compound 3,3,5-trimethylcyclohexylsalicylate appears as a viscous liquid or light yellow to slightly tan oil. It is categorized as a benzoate ester and belongs to the phenol family. It is a derivative of salicylic acid. 3,3,5-Trimethylcyclohexyl Salicylate, a UV filter, provides protection against the harmful impact of UVB (280-315 nm) and UVA II (315-340 nm) radiations on the skin. Notably, 3,3,5-Trimethylcyclohexyl Salicylate specifically absorbs short-wave UVB rays.
