Physiological cooling compounds of the structure: ##STR00001##
where R.sub.1 is p-menthyl or 2,3,4-trimethylpent-3-yl group and R.sub.2-R.sub.8 are hydrogen or alkyl groups. The combination of R.sub.2-R.sub.8 is such that the N-alkyl group is a branched C.sub.5 alkyl or branched or linear C.sub.6-C.sub.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.
