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: The present invention relates to a composition comprising: (a) a fragrance oil wherein the fragrance oil comprises: (i) one or more perfume raw materials with a high odour impact 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 where in the top note perfume raw materials have a boiling point of less than 250° C.

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.
