The invention concerns novel chemical compounds, namely citronellyl lactate and dihydrocitronellyl lactate and their optically active forms. The invention also concerns the method for obtaining them. The invention further concerns their use in the field of perfumes.

Citronellyl and/or dihydrocitronellyl lactates, their preparation and their use

The present invention relates to a process for the production of perfuming compositions, to perfumed products, and to products obtained therefrom. More specifically, the present invention concerns a process for the production of perfuming compositions, perfumed products and substances for perfumery characterized in that they comprise, as an active ingredient with an influence on the scent, an effective quantity of an alkylsalicylic acid ester.

Method for preparing scenting compositions and scented products, and resulting products

Process for the producing of pentenenitriles

The vanillic acid esters, for example, methyl or ethyl vanillate, are effective perfuming or olfactory agents for a wide variety of compositions, substrates and articles, whether perfumes, skin- and haircare products, cosmetics, shaving preparations, toiletries, deodorants and antiperspirants, room deodorizers, etc.

Vanillic acid ester perfuming agents

Process for preparing 1-chloro-1,3-butadiene, which consists in gas-phase dehydrochlorinating a dichlorobutene selected from 3,4-dichloro-1-butene and 1,4-dichloro-2-butene, in the presence of a catalyst selected from lanthanum phosphate and lanthanum phosphate doped with an alkali or alkaline-earth metal.
