Abstract
The present invention provides divinyl ether derivatives capable of releasing in a controlled manner at least one active aldehyde and/or ketone into the surrounding environment. The invention relates to the use of these divinyl ether derivatives as perfuming or flavoring ingredients, as well as to the perfuming compositions and consumer articles containing them.
Claims16
A compound selected from the group consisting of 1,1′-oxybis-1-decene, 1,1′-oxybis-1-octene, 1,1′-oxybis-1-nonene, 1,1′-oxybis-1-undecene, 1,1′-oxybis(2-methyl-1-decene), 1,1′-oxybis(2-methyl-1-undecene), 1,1′-[oxybis(1-propene-1,3-diyl)]dibenzene, 1,1′-[oxybis(1-butene-1,3-diyl)]dibenzene, 1,1′-[oxybis(2-methyl-1-butene-1,4-diyl)]dibenzene, 1,1′-[oxybis(3-methyl-1-pentene-1,5-diyl)]dibenzene, 1,1′-oxybis(1,6-nonadiene), 1,1′-oxybis(3,5,5-trimethyl-1-hexene), 1,1′-oxybis(1,9-undec-diene), 1,1′-oxybis(1,10-undec-diene) and 1,1′-[oxybis(1-propene-1,3-diyl)]bis(4-tert-butylbenzene).
A perfuming composition comprising:
- a) at least one compound of Formula (I):
- wherein R1 and R2 are identical or different and represent each a C2 to C15 hydrocarbon group and both R3 represent, independently from each other, a hydrogen atom or a methyl group, provided that compounds of Formula (I), wherein R1 is a C8 mono alkenyl group and R2 is selected from the group consisting of the C4 to C10 alkyl groups and the C9 8-alkenyl group, are excluded;
- b) at least one ingredient selected from the group consisting of a perfumery carrier and a perfumery base;
- and
- c) optionally at least one perfumery adjuvant.
A consumer article, comprising:
- a) as active ingredient, at least one compound of Formula (I):
- wherein R1 and R2 are identical or different and represent each a C2 to C15 hydrocarbon group and both R3 represent, independently from each other, a hydrogen atom or a methyl group, provided that compounds of Formula (I), wherein R1 is a C8 mono alkenyl group and R2 is selected from the group consisting of the C4 to C10 alkyl groups and the C9 8-alkenyl group, are excluded;
- and
- b) a consumer product base.
A method to confer, enhance, improve or modify odor properties of a surface, comprising contacting or treating the surface with a compound of Formula (I) under conditions sufficient to release aldehyde or ketone compounds therefrom, wherein Formula (I) is:
- wherein R1 and R2 are identical or different and represent each a C2 to C15 hydrocarbon group and both R3 represent, independently from each other, a hydrogen atom or a methyl group, provided that compounds of Formula (I), wherein R1 is a C8 mono alkenyl group and R2 is selected from the group consisting of the C4 to C10 alkyl groups and the C9 8-alkenyl group, are excluded.
