A mixtures which contain (a) at least one phenylalkenal of formula (I) wherein R
1
and R
2
independently represent hydrogen, a methyl or phenyl group, R
3
represents hydrogen, a phenyl group, alkenyl group or a linear or branched alkyl group with 1 to 5 carbon atoms, and the broken double lines independently represent a single bond or a double bond, and (b) at least one physiological cooling agent.
Proposed are preparations, comprising special amides and menthol or menthol compounds or aromatic substances, characterized in that they have improved flavor and scent properties, and also that they allow the production of preparations, particularly emulsions with improved shelf life.

Suggested is a process for the production of solid cooling agents, wherein a pre-scraped melt, i.e., a melt of menthol compounds with added seed crystals is applied to a pre-cooled area by even deposition of drops.
The invention relates to coolant mixtures containing: (a) at least one compound of formula (I), (b) at least one compound of formula (II) in which R1 stands for hydrogen or a methyl group, R2 stands for a methyl, ethyl or propyl group and n stands for 0, 1, or 2, and if applicable (c) an additional component.
