The present invention relates to a method of preparing liquid compositions essentially consisting of menthol and menthyl lactate and the use of such compositions as a cooling agent, flavouring agent and/or fragrance agent, products containing such compositions and methods of providing a physiological cooling effect by applying such compositions.
Menthyl lactate process

A simple, high-yield process for making menthyl lactate (ML) is disclosed. Menthol and lactic acid react to produce a mixture comprising menthyl lactate and one or more higher lactoyl esters of ML. Hydrolysis of the esterification mixture follows in the presence of aqueous base under conditions effective to convert the higher lactoyl esters to menthyl lactate. Coincidentally, the conditions minimize hydrolysis of menthyl lactate to menthol, thereby maximizing the overall yield of ML.
