Abstract: A fragrance composition for use in hydrophobic systems, such as candles, comprising at least one odorant selected for having a minimum cold throw value (?) and a minimum hot throw value (?) is disclosed. A method of formulating a fragrance composition for hydrophobic systems, such as candles, comprising selecting at least one odorant to form a desired fragrance, each odorant having a minimum cold throw value (?) and hot throw value (?), and incorporating the fragrance into a hydrophobic carrier, such as wax material, is disclosed.

Abstract: Perfume compositions and method of formulating perfume compositions designed for use in rinse-off or high dilution systems provide a sustained linear release and/or a delayed release, with the odorants selected according to their mass transfer values, odor detection thresholds and/or calculated odor indices.

Abstract: Perfume compositions and method of formulating perfume composition are designed for use in wash-off system to provide either a desired initial release with minimal residual perfume on the targeted system, a long sustained release of fragrance, or a residual deposition of fragrance after use, based upon the odorants selected according to their mass transfer values, odor detection thresholds and/or calculated odor indices.

Abstract: The present invention relates to a composition comprising: (a) a fragrance oil wherein the fragrance oil comprises: (i) greater than about 50%, by weight of the fragrance oil, of perfume raw materials with high odour impact perfume raw materials which have an odour detection threshold of less than, or equal to, about 50 parts per billion; (ii) less than about 5%, by weight of the fragrance oil, of top note perfume raw materials wherein the top note perfume raw materials have a boiling point of less than about 250° C. at 1 atmosphere pressure (b) an entrapment material which is selected from the group consisting of polymers; capsules, microcapsules, and nanocapsules; liposomes; pro-perfumes; film formers; absorbents; cyclic oligosaccharides and mixtures thereof. (c) greater than about 50%, by weight, of a volatile solvent.

Abstract: A composition comprising: (a) a fragrance oil comprising: (i) top note perfume raw material, or mixture of perfume raw materials, with a boiling point of less than, or equal to, about 250° C. at 1 atmosphere pressure; (ii) middle or base note perfume raw material, or mixture of perfume raw materials, with a boiling point of greater than 250° C. at 1 atmosphere pressure; (b) an entrapment material which is selected from the group consisting of polymers; capsules, microcapsules and nanocapsules; liposomes; pro-perfumes selected from more than 1 type of pro-chemistry; film formers; absorbents; cyclic oligosaccharides and mixtures thereof; (c) greater than 50% volatile solvent; wherein the weight ratio of the top note perfume raw materials to middle or base note perfume raw materials within the fragrance oil is in the range from about 1:20 to about 20:1.

Abstract: An improved fragrance delivery system capable of providing controlled release of fragrance molecules in various consumer products is composed of a polymer having covalently bound fragrance moieties that are releasable in the form of fragrance molecules. Certain embodiments comprise globular polymer particles in which unbound fragrance molecules are occluded, absorbed and/or adsorbed. Certain other embodiments incorporate fragrance monomer units, which achieve reduced residuals upon complete release of the fragrance.
