Abstract
The present invention relates to a cooling composition for producing cooling particles comprising a solvent component and dissolved therein (1R,2S,5R)-N-(4-methoxyphenyl)-5-methyl-2-(1-methylethyl)-cyclohexane-carboxamide. The present invention further relates to cooling particles comprising a cooling composition according to the invention, oral preparations comprising cooling particles, new uses of cooling particles, a process for the production of cooling particles as well as the use of a solvent component for dissolving cooling agents.
