Solvent composition based on an oxide of an organic sulfide with masked odour

摘要

The invention relates to solvent compositions predominantly comprising at least one oxide of an organic sulfide, more particularly dimethyl sulfoxide, to which is added at least one odour-masking agent comprising at least one compound selected from monoesters, diesters or triesters, alcohols, ketones, aldehydes and terpenes.

1. A solvent composition comprising:
a) at least 50% by weight of at least one oxide of an organic sulfide of general formula (1): in which
X and Y, which may be identical or different, are chosen, independently of each other, from oxygen, sulfur, —SO—, —SO2—, —NH—and —NR″—;a and b, which may be identical or different, represent, independently of each other, 0 or 1; n is equal to 1 or 2;R, R′ and R″, which may be identical or different, are chosen, independently of each other, from a linear or branched alkyl radical containing from 1 to 12 carbon atoms, a linear or branched alkenyl radical containing from 2 to 12 carbon atoms, and an aryl radical containing from 6 to 10 carbon atoms; R, R′ and R″ possibly being substituted with radicals chosen from alkyl, alkenyl, aryl and halogen, and possibly containing one or more heteroatoms chosen from O, S, N, P and Si; R and R′ also possibly forming, together with the atoms that bear them, a hydrocarbon-based cyclic structure optionally containing one or more heteroatoms chosen from O, S and N, said cyclic structure comprising in total 5, 6, 7, 8 or 9 ring members; and b) from 10 ppm to 2%, by weight relative to the total weight of the composition, of at least one odor-masking agent comprising at least one compound chosen from monoesters, diesters andor triesters, alcohols, aldehydes, ketones, and terpenes, wherein the aldehydes and ketones are of formula Ra—CO—Rb, in which Ra represents a linear or branched hydrocarbon-based chain comprising from 1 to 6 carbon atoms, optionally comprising one or more unsaturation(s) in the form of double bonds, and Rb represents a hydrogen atom, a cyclic hydrocarbon-based chain or a linear or branched hydrocarbon-based chain optionally substituted with a cyclic structure, Rb comprising from 6 to 12 carbon atoms, optionally comprising one or more unsaturation(s) in the form of double bonds and being optionally substituted with one or more hydroxyl groups.
