The present invention relates to the field of perfumery. More particularly, it concerns polymers derived from siloxane derivatives and comprising at least one β-thio carbonyl moiety capable of liberating an active molecule such as, for example, an α,β-unsaturated ketone or aldehyde. The present invention concerns also the use of polymers in perfumery as part of a perfuming or malodor counteracting composition as well as the perfuming compositions or perfumed articles comprising the invention's compounds.

A perfume composition having controlled release of phytoncides in an atmosphere in order to generate an air condition resembling the air environment of a forest is provided. The perfume composition includes a) at least about 0.6% by weight of at least one phytoncide; and b) a perfume mixture including (i) at least one solvent; and (ii) at least one fragrance ingredient. At least about 25% by weight of the at least one phytoncide is selected from the group consisting of pinene alpha, pinene beta and combinations thereof.

The present invention is related to substituted butanol derivatives of the formula: ##STR00001##

Such compounds are useful in flavor or flavor compositions.

The present invention relates to the field of perfumery. More particularly, it concerns short chain β-sulfur carbonyl moieties capable of liberating an active molecule, such as a perfuming α,β-unsaturated ketone or aldehyde. The present invention concerns also the use of said compounds in perfumery as well as the perfuming compositions or perfumed articles comprising the invention's compounds.

A method of extending the olfactory effect of a fragrance added to a washed item, comprising the addition to the wash of the fragrance, the fragrance comprising at least one compound selected from the group consisting of ethyl (Z)-2-acetyl-4-methyltridec-2-enoate; ethyl N,S-bis(4-oxo-4-(2,6,6-trimethylcyclohex-3-en-1-yl)butan-2-yl)cysteinate; 4-(dodecylthio)-4-methylpentan-2-one; 1-butoxy-3-((1E,4Z)-hepta-1,4-dien-1-yl)benzene; and 2-ethoxy-4-((1E,4Z)-hepta-1,4-dien-1-yl)phenol.

A washed item in which the washing utilized at least one of the compounds and which was then stored, for example, in a cupboard, closet or drawer, is found to have retained a substantial proportion of the fragrance, and for a longer time

The present invention relates to the use of an ether or an ester of a tertiary alkanol or of mixtures of two or more ethers or esters of tertiary alkanols or of a stereoisomer thereof or of a mixture of two or more stereoisomers thereof as aromachemicals; to the use thereof for modifying the scent character of a fragranced composition; to an aroma chemical composition containing an ether or an ester of tertiary alkanol or of mixtures of two or more ethers or esters of tertiary alkanols or of a stereoisomer thereof or of a mixture of two or more stereoisomers thereof; and to a method of preparing a fragranced composition or for modifying the scent character of a fragranced composition. The invention further relates to specific ethers or esters of tertiary alkanols.

The present application relates to fragrance compositions comprising perfume raw materials that resist fragrance habituation, and methods for making and using the fragrance compositions.

The present invention relates to a novel compound and its use as a fragrance material.

The present invention is directed to the use 4,8,11-dodecatrienal to impart a clean aroma impression to a composition. The present invention is further directed to compositions comprising 4,8,11-dodecatrienal and at least one aroma chemical as well as to compositions comprising 4,8,11-dodecatrienal and at least one further component selected from the group consisting of aroma chemicals, surfactants, oil components, anti-oxidants, deodorant-active agents and solvents, wherein the composition does not comprise 1,5,9-cyclododecatriene.
