Described herein are essential oils, extracts, apparatus and methods for the extraction of the essential oils and extracts from plant biomass using microwaves.

The present invention relates to new classes of odorous oximes and their ketone intermediates (odorants) which are useful as fragrance or flavor materials in particular in providing cassis, catty, tropical, green, coniferous, thuya, floral and/or fruity olfactory notes to perfume, aroma or deodorizing/masking compositions.

Perfume compositions comprise between 10% and 30% in total weight of perfume ingredients selected from two groups, Group A, Group B, with the provisos that over 5% but less than 15% of the perfume composition must comprise Group A ingredients, and for compositions comprising less than 10% of Group A ingredients in the aggregate percentage of Group B ingredients present must be at least equal to the expression (2*/10A %) where A % is the total percentage of Group A ingredients in the composition.

An object of the present invention is to provide a polyphenol-containing solid composition that enables efficient ingestion of a polyphenol. This object can be achieved by a solid composition containing (1) an amorphous poorly water-soluble polyphenol, (2) a hydrophilic polymer, and (3) at least one nonionic surfactant selected from the group consisting of polyglycerol fatty acid esters, sucrose fatty acid esters, and lecithins.

The present invention relates to freshening compositions, devices comprising same and methods of using and manufacturing same. A freshening composition of this invention may comprise (i) from about 0.1 wt % to about 95 wt % perfume raw material, (ii) from about 0.01 wt % to about 90 wt % fragrance release modulator, and (iii) from about 1.0 wt % to about 95 wt % solvent. Some freshening composition further comprise an ingredient having a functional activity. Disclosed are passive and active air or surface freshening products comprising a freshening composition that allow controlled and customized release of the freshening composition or of a component thereof into or onto an environment. The addition of a fragrance release modulator to formulate a freshening composition of the present invention allows the modulation of the release of the freshening composition or of a component thereof.

The present invention refers to substituted cyclopentyl- and cyclohexyl-derivatives of formula (I) ##STR00001## wherein n, R.sup.1, R.sup.2, R.sup.3, R.sup.4 and X have the same meaning as given in the description. The invention further refers to fragrance compositions and fragranced articles comprising them.

The present invention relates to novel compounds and their use as fragrance materials.

Disclosed is a cyclopropanation process comprising the step of reacting an alkene compound having at least one carbon-carbon double bond with at least one dihaloalkane. The reaction is carried out in the presence of (i) particulate metal Zn, (ii) catalytically effective amount of particulate metal Cu or a salt thereof, (iii) at least one haloalkylsilane, and (iv) at least one solvent.

The present invention relates to freshening compositions and devices comprising same that comprise a composition having a viscosity of from about 1 mPa.Math.s to about 50,000 mPa.Math.s comprising malodor reduction compositions and methods of making and using such compositions. The disclosed malodor reduction compositions do not unduely interfere with the scent of the freshening compositions and devices that comprise such technologies and the perfumed or unperfumed situs that is treated with such freshening compositions and devices.

Described herein are perfuming compositions and perfumed consumer products including, as perfuming ingredients, cyclopentanone compounds of formula

##STR00001##

in a form of any one of its stereoisomers or a mixture thereof, where n represents 1.
