A compound of formula (I) or (A) in the form of any one of its stereoisomers or a mixture thereof, and wherein and wherein

Benzodioxole derivatives as watery odorants

The present invention relates to compounds of formula (I) in the form of any one of its stereoisomers or a mixture thereof, and wherein Rrepresents a substituent of the benzene ring and is a bromine atom or a linear, branched or cyclic Calkyl, alkenyl, alkoxy or alkenyloxy group; Rrepresents a Calkyl group; and Rrepresents a hydrogen atom or a methyl or ethyl group; and their use as perfuming ingredients, for instance to impart odor notes of the watery/ozone type. 

The invention relates to a method to confer, enhance, improve or modify the odor properties of a perfuming composition or of a perfumed article, by adding to the composition or article an effective amount of at least a compound of formula (I) 

Organic carbonates with vanilla odor

The present invention relates to the field of perfumery. More particularly, it concerns &#x3b1;-substituted cyclopentanecarbonitriles or cyclohexanecarbonitriles. These compounds are valuable perfuming ingredients having fruity or jasminic odor notes. The present invention also concerns the compositions or articles containing the compound.

&#x3b1;-substituted cyclopentanecarbonitriles or cyclohexanecarbonitriles and their use in perfumery

The present invention relates to the field of perfumery. More particularly, it concerns specific oxime or nitrite derivatives of 4-dodecene, which are useful perfuming ingredients in particular to impart natural mandarin odor notes.

4-dodecene derivatives as perfuming ingredients

The present invention concerns a compound of formula wherein the wavy line indicates that the double bond in position 3 is in a configuration E or Z or a mixture thereof, and R is a C-Calkyl or alkenyl group, which is a useful perfuming ingredient capable of imparting odor notes of the violet leaves type as well as a green/fruity aspect.

Unsaturated ethers as perfuming ingredients

The present invention relates to a perfuming ingredient of a compound of formula in the form of any one of its isomers or of a mixture thereof, and having a boiling point above 250&#xb0; C., as measured at a pressure of 1013 mbar and its use in a method to confer, enhance, improve or modify the odor properties of a perfuming composition or perfumed article. The perfuming compositions and perfumed articles having the desirable odor characters are also part of this invention.

Citronella and floral perfuming ingredient

The present invention relates to the use as perfuming ingredient of a 3,3-dimethylbicyclo[2.2.1]hept-2-yl or a 3,3-dimethylbicyclo[2.2.1]hept-5-en-2-yl derivative, as well as to the compositions or articles containing this compound.

Perfuming ingredients of the woody type

The present invention relates to the use as perfuming ingredient of a compound of formula wherein R represents a hydrogen atom or a methyl or ethyl group, and

Non-cyclic hindered ketones as perfuming ingredient

Use of tertiary alcohols or esters as perfuming ingredients

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

The use of 1-methoxy-2-methyl-3-phenylpropane, 3-methoxy-2,2,3-trimethyl-1-phenylbutane or of 1-(2-methoxypropyl)-4-methylbenzene as perfuming ingredients is described. These two compounds possess an excellent stability in aggressive media and/or at high pH-values, which renders them very useful for application in chlorine bleach. The odor of these two compounds can be described as being of the green type with a nice, strong floral note.

Use of 1-methoxy-2-methyl-3-phenylpropane,

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.
