An encapsulated perfume composition wherein the shell contains a polyurea resin and the core contains a perfume comprising an aldehyde-containing perfume ingredient or ingredients, a non-aromatic cyclic perfume ingredient, and an alkyl salicylate and/or a 2,2,2-trisubstituted acetal,

A perfume composition includes groups of perfume components that produce enhanced sensory performance. The composition includes components that have synergistic odor properties.

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.

A malodor reducing composition is provided. The composition includes a perfume mixture including (a) at least one odor-reducing material; and (b) at least one N-heterocycle selected from an aromatic N-heterocyclic moiety and N,S-heterocyclic moiety. The at least one odor-reducing material exhibits an Odor Value (OV) having a common decimal logarithm (log.sub.10OV) of greater than about 5.5.

A freshening composition is provided. The freshening composition includes about 0.02 wt. % to about 1.0 wt. %, based on the weight of the composition, of a sulfur-containing pro-perfume. The freshening composition further includes about 0.2 wt. % to about 1.4 wt. %, based on the weight of the composition, of a perfume mixture, the perfume mixture comprising at least one perfume material selected from the group consisting of: 3-(1,3-Benzodioxol-5-yl)-2-methylpropanal, canthoxal, vanillin, ethyl vanillin, citral, ligustral, cinnamic aldehydes, and combinations thereof. The freshening composition also includes a carrier.

A composition containing a malodor counteracting compound and a method for using the compound for counteracting a malodor in air space or a substrate is provided.

The aspects presented herein provide fragrance compositions having an olfacive profile that changes with time, wherein the fragrance compositions comprise at least two contrasting perfume accords that provide an olfactory modulating effect, wherein the perfume formulation delivers a desirable scent with increased perceived intensity and improved longevity of perception.

A method for extracting an essence or perfume oil from pistachio hulls, the method comprises separating the pistachio green hulls or velvet hulls from pistachio nuts using an industrial separator and subjecting the hulls to an extraction method, which causes release of the essence from essence containing glands, wherein the essence mixes with steam forming vapors. The method further comprises distilling the vapors to form a liquid comprising the essence mixed with an aqueous component and separating the essence from the aqueous component. Compositions and methods for extracting perfume oil from pistachio hulls are described.

The present invention is related to a novel and improved process for the preparation of 3,7-dimethylnonan-1-ol.

A compound is provided of Formula (I), wherein R.sup.1 represents a C.sub.3 to C.sub.20 hydrocarbon group derived from an alcohol of formula R.sup.1OH, from a formate of formula R.sup.1OCH═O, or a cinnamyl aldehyde of Formula (II) wherein a compound of Formula I is capable of releasing a compound, when oxidized, selected from the group consisting of a fragrant alcohol of formula R.sup.1OH, a fragrant formate ester of formula R.sup.1OCH=0 and aryl aldehyde of Formula (III), wherein R.sup.2 is, independently, hydrogen atom, hydroxyl group, optionally substituted C.sub.1-C.sub.6 alkyl group, C.sub.1-C.sub.6 alkoxy group, or -0(C=0)CH(CH3).sub.2 wherein any two of R.sup.2 may form an optionally substituted 5 or 6 membered ring. The compounds are useful for example as a precursor for the prolonged delivery or release of fragrant compounds such as fragrant alcohols, fragrant aldehydes or fragrant formates. ##STR00001##
