Claims18
A method of preparing a solution of menthyl lactate, wherein the final concentration of menthyl lactate is higher than that achievable by dissolving menthyl lactate in a neat solvent, by:
- liquefying menthyl lactate;
- and
- combining the liquefied menthyl lactate with menthol carboxamide and the solvent.
A solution consisting essentially of menthyl lactate and menthol carboxamide dissolved in a solvent, characterized in that the final concentration of menthyl lactate is higher than that achievable by dissolving menthyl lactate alone in the solvent.
