The present invention relates to perfuming compositions and consumer products that contain compounds of formula in the form of any one of its stereoisomers or a mixture thereof and wherein one R represents a methyl group and the other R is a hydrogen atom. The compounds are useful as perfuming ingredients in particular to impart lily of the valley/gardenia odor notes to the composition or product.

Alcohol with floral odor

The present invention relates to compounds of formula (I) in the form of any one of its stereoisomers or a mixture thereof and wherein one R represents a methyl group and the other R is a hydrogen atom; which are useful as perfuming ingredients. 

The present invention concerns the use as perfuming ingredient of a lower alkyl ester of 4,6,6-trimethyl-1,3-cyclohexadiene-1-carboxylate or 4,6,6-trimethyl-3-cyclohexene-1-carboxylate. These compounds are able to impart odor notes of the spicy/saffron type.

Perfuming ingredients with saffron odor

The present invention relates to a compound of formula wherein R represents a methyl or an ethyl group, in the form of any one of its isomers or of a mixture thereof. The invention relates also to the use of such a compound as a perfuming ingredient capable of imparting a odorant note of the rose type. Moreover, the invention concern also the perfumed article or perfuming composition containing a compound according to the invention.

Unsaturated ester as perfuming ingredient

The present invention relates to the use as a perfuming ingredient of 2-methyl-3-hexanone-oxime of formulain which the wavy line represents a bond having a configuration of the type (Z) or (E) or a mixture of the two configurations.

Oxime as perfuming ingredient

The invention concerns (1-ethoxyethoxy-cyclododecane) which, although its smell is not noticed by a large number of people, can advantageously be used in a perfume composition as perfume exalting fixative.

Use of (1-ethoxyethoxy)cyclododecane in a perfume composition as perfume fixative and/or enhancer

Compounds consisting of indan derivatives of the formula: ##STR1## Wherein X or Y represents an aldehyde or an acetal group and the other represents a hydrogen, and R represents a hydrogen or a methyl group and the t-butyl group is at the 5 or 6 position of the phenyl ring. Where these compounds are useful as perfuming ingredients for the preparation of perfuming compositions and perfumed articles to which they impart floral odor notes.

Aromatic compounds, processes for their preparation and their use in

7-Propyl-2H,4H-1,5-benzodioxepin-3-one and its use as perfuming ingredient is described. The said compound develops an aldehyde-type fragrance typical of the aliphatic unsaturated aldehydes of current use in products like soaps, shampoos, detergents for textiles or for multiple purposes, but, contrary to these aldehydes, proved to be completely stable, chemically and olfactively, in aggressive media characteristic of these products.

Benzodioxepinone and its use in perfumery

Perfuming ingredients which include at least one macrolide of formula ##STR1## having a double bond in one of the positions indicated by the dotted lines and wherein the symbol R represents a hydrogen atom or a methyl radical, are described. They are useful for the preparation of perfumes and perfumed consumer products to which they impart musky odors with original nuances.

Fragrant macrocyclic lactones

Described herein are compounds of the formula ##STR1## wherein R represents a hydrogen atom or a methyl radical and X stands for a --CHO, or a --CN group, are useful as perfuming ingredients for preparing perfuming compositions and a variety of perfumed articles, to which they impart sandalwood-type odor notes, together with marine, ozone type odor characters, such that said compositions and articles thus acquire a 'transparent' connotation. The aldehydes of formula (I) are also useful as starting products for the preparation of the corresponding fragrant alcohols and nitriles.

Use of dihydrobenzofuranones as perfuming ingredients

3-(2,2-Dimethyl-propyl)-pyridine is used to impart, improve or modify the odor properties of a variety of consumer products. In particular, it develops fruity-fresh type notes.

Utilization of an alkyl-substituted pyridine as a perfuming ingredient

(1RS,5RS)-5-Methyl-exo-tricyclo[6.2.1.0.sup.2,7 ]undecan-4-one, as well as the compositions which contain a preponderant amount of this compound together with its isomer (1RS,5SR)-5-methyl-exo-tricyclo[6.2.1.0.sup.2,7 ]undecan-4-one, are useful as perfuming ingredients for the preparation of perfuming compositions and perfumed articles, to which they impart aromatic, thujonic and herbaceous odors.

Composition containing a preponderant amount of

1,3-Undecadien-5-yne and its (E) and (Z) configuration isomers are useful perfuming ingredients for the preparation of perfuming bases and a variety of perfumed consumer products, to which they impart odor characters of the galbanum, floral, fruity-citrus type.
