Physiological cooling compounds of Structure 1, where R 1 is p-menthyl or 2,3,4-trimethylpent-3-yl group and R 2 -R 8 are hydrogen or alkyl groups. The combination of R 2 -R 8 is such that the N-alkyl group is a branched C 5 alkyl or branched or linear C 6 -C 8 alkyl group. The new carboxamides are valuable sensory ingredients which provide long-lasting cooling sensation and freshness in personal care, oral care, cosmetic products, pharmaceutical preparations, confectionary, food and beverages. |
