In the title chiral sulfinic acid ester, C18H26O4S, the cyclo-hexane ring of the menthyl fragment adopts a chair conformation. The mol-ecular shape is defined by the dihedral angle of 47.87 (8)° between the mean planes of the cyclo-hexane and benzene rings. In the crystal, mol-ecules related by the screw axis are connected into chains along [010] by weak Car-H⋯O=S contacts.
