Patent ID: 8344025

Claim:
A composition comprising one or more compounds of formula (I) wherein: B is a hydrocarbon residue selected from the group consisting of: in which the dashed line indicates a bond which links the hydrocarbon residue B with the adjacent oxygen atom in formula (I), X is NR 1 R 2 or SR 3 , and R 1 , R 2 , and R 3 are independently selected from the group consisting of hydrogen and an optionally substituted organic residue with 1 to 12 C atoms, wherein, optionally in NR 1 R 2 , the residues R 1 and R 2 are covalently bonded together with omission of one hydrogen atom in each case to form a ring; provided that when the composition comprises only one compound of formula (I), the one compound is not selected from the group consisting of wherein at least one compound of formula (I) is selected from the group consisting of: (L)-menthyl oxamate, rac-menthyl oxamate, menthyl N-methyl oxamate, menthyl N,N-dimethyl oxamate, menthyl N-ethyl oxamate, menthyl N,N-diethyl oxamate, menthyl N-propyl oxamate, menthyl N,N-dipropyl oxamate, menthyl N-isopropyl oxamate, menthyl N,N-diisopropyl oxamate, menthyl N-cyclopropyl oxamate, menthyl N-butyl oxamate, morpholin-4-yl-oxo-acetic acid (1R,2S,5R)-2-isopropyl-5-methylcyclohexyl ester, menthyl N-(2-methoxyethyl) oxamate, menthyl N-(3-methoxypropanol) oxamate, menthyl N-(2-hydroxyethyl) oxamate, and menthyl N-(3-hydroxypropyl) oxamate.
