A method of providing a cooling sensation to the skin or mucous membranes of the mouth by applying thereto a quantity of at least one chemical compound sufficient to cause a desirable degree of cooling sensation, the chemical compound comprising a compound of formula I: in which R1, R2 are independently in either the meta- or para-position and independently comprise at least one of hydrogen, halide, C1-C3 alkyl (linear or branched), halide, C1-C3 alkoxy, nitro, nitrile, amide or ester; R3 comprises at least one of C1-C5 alkyl or C1-C5 alkenyl groups (linear or branched), R4 comprises at least one of hydrogen, C1-C3 alkyl (linear or branched), or a halide. The cooling effect provided is in some instances superior to that achievable by any of the known commercial cooling agents.
