Kinetic resolution of racemic epsilon-lactones by Pig Liver Esterase give optically active R (+) epsilon-lactones. When alkyl group is higher than propyl, Horse Liver Esterase leads to the destruction of the opposite enantiomer. Enantiomeric excess is easily evaluated by G.C. on a chiral stationary phase.

Personal care compositions, such as oral care and skin care compositions containing a flavor/perfume system comprising one or more coolants. The pleasant cool sensation provided by a coolant is enhanced in terms of quicker onset, greater intensity, impact or longer duration, which improves appeal and acceptability of the compositions to consumers.
