Abstract

L'invention concerne des précurseurs de parfums. En particulier, l'invention concerne l'utilisation de plusieurs classes de composés qui peuvent servir de précurseurs de parfums, par exemple, dans des produits de consommation tels que des produits cosmétiques, et plus précisément, des déodorants et des antitranspirants. Ces composés sont normalement sans, ou pratiquement, sans odeur, mais lors de leur contact avec la peau, comme par exemple dans les compositions de soins de beauté ou de soins personnels, ils dégagent un parfum en libérant un alcool odoriférant.
