Overview

4-tert-Butylcyclohexanol (CAS 21862-63-5 ), also known commercially as Padaryl, is a fragrance and flavor ingredient used across personal care and consumer goods formulations. It delivers a clean, woody, camphoraceous character that perfumers and flavorists select to build or modify scent profiles.
