Suggested is fragrance composition comprising or consisting of a selection of specific nitriles showing improved stability against decomposition and discoloration.

The present application relates to perfume raw materials, perfume delivery systems and consumer products comprising such perfume raw materials and/or such perfume delivery systems, as well as processes for making and using such perfume raw materials, perfume delivery systems and consumer products. Such perfume raw materials and compositions, including the delivery systems, disclosed herein expand the perfume communities' options as such perfume raw materials can provide variations on character and such compositions can provide desired odor profiles.

The present application relates to antiperspirant compositions comprising nitrogen-based and/or oxygen based perfume raw materials, and methods for making and using the antiperspirant compositions.

The invention relates to a malodor counteractancy or counteracting (MOC) method that resorts to the use of specific malodor counteracting (MOC) mixtures of fragrance ingredients. More particularly, the invention relates to new MOC compositions capable of neutralizing or masking in an efficient manner malodors of a large variety of such as body or as malodors, kitchen malodors, toilet and bathroom malodors, and tobacco malodor. The novel MOC compositions of the invention contain at least one nitrite material in combination with another fragrance material and can be used in any finished consumer products such as air fresheners, kitchen or toilet/bathroom cleaning or freshening products, textile treatment products and products for application on the human skin or hair, or on animal fur, litter containers or cages.

A perfume composition comprising an effective amount of at least one alkadienenitrile selected from 4,8-undecadienenitrile and isomers thereof, 4,9-dodecadienenitrile and isomers thereof, and 4,10-tridecadienenitrile and isomers thereof. The isomers of 4,8-undecadienenitrile comprise Z,Z-4,8-undecadienenitrile, E,E-4,8-undecadienenitrile, and mixed Z/E isomers of 4,8-undecadienenitrile; the isomers of 4,9-dodecadienenitrile comprise Z,Z-4,9-dodecadienenitrile, E,E-4,9-dodecadienenitrile, and mixed Z/E isomers of 4,9-dodecadienenitrile; and the isomers of 4,10-tridecadienenitrile comprise Z,Z-4,10-tridecadienenitrile, E,E-4,10-tridecadienenitrile, and mixed Z/E isomers of 4,10-tridecadienenitrile. A composition comprising an effective amount of at least one alkadienenitrile selected from 4,8-undecadienenitrile and isomers thereof, 4,9-dodecadienenitrile and isomers thereof, and 4,10-tridecadienenitrile and isomers thereof. Processes for the preparation of the isomeric alkadienenitriles are provided. The isomeric alkadienenitriles have a range of fresh, citric, ozonic and floral notes of exceptional strength.

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

A volatile composition having: (i) greater than 30% of a scented hydrophobic material by weight of the volatile composition, wherein the scented hydrophobic material comprises one or more volatile compounds; and (ii) greater than 20% of a regulating scent intensity (RIS) composition by weight of the volatile composition.

The RIS composition has at least two of: a first regulating scent intensity component (RIS component) having a high average vapor pressure (VP); a second RIS component having a medium average VP; and a third RIS component having a low average VP;

The average VP of each of said one or more volatile compounds is lower than at least one of the high, medium and low average VPs of the first, second and third RIS components at the same temperature.

A scent intensity regulating composition (RIS composition). The RIS composition includes at least two of:

a first scent intensity regulating component (RIS component) having an average vapor pressure (VP) greater than 0.3 Torr at 25° C.;
a second RIS component having an average VP from 0.07 to 0.3 Torr at 25° C.; and
a third RIS component having an average VP from 0.0099 to 0.07 Torr at 25° C.

Each of the first, second, and third RIS components is characterized by an Odor Detection Threshold (ODT) of greater than 20 ppb.
