| 摘要 |
Ketals, preferably glycerol ketals such as, for example, 1-menthone glycerol ketal or 3,3,5-trimethylcyclohexanone glycerol ketal, have a physiological cooling effect and are therefore suitable as active compounds in compositions which are intended to cause a sensation of freshness on human skin or mucous membrane. |
