A geometrical isomer composition excellent in odor and in chemical resistance, which is applicable to a base material containing a strongly alkaline chemical or a strongly acidic chemical, which can suppress the deterioration with time and the color change of the base material in the case that the material is exposed to light, and which also have highly palatable and unique fruity floral fragrance. The composition is produced by mixing 93 to 99% by weight of optically active ethyl trans-2,2,6-trimethylcyclohexylcarboxylate represented by Formula-1 or a mixture thereof and 7 to 1% by weight of optically active ethyl cis-2,2,6-trimethylcyclohexylcarboxylate represented by Formula-2 or a mixture thereof, respectively.
