The present invention concerns enhancements in the cooling effects of certain physiological coolant-containing compositions such as topically applied cosmetic, toiletry or pharmaceutical products, wherein the cooling effect of the physiological coolants is enhanced by the addition of a substance according to formula (I) or dermatologically acceptable salts thereof: R1—CR2(OR3)—CO—NR4—CR5R6—X—OR7  (I) It was found that substances represented by formula (I) are capable of bringing about greater cooling effects from reduced concentrations of physiological coolants without behaving as physiological coolants themselves, thereby enabling the preparation of compositions that do not necessarily have the characteristic minty odor of menthol-containing products and/or to allow greater freedom in creating perfumed products.
