A fragrance-containing microparticle of water-insoluble polymeric material, the polymer having a glass transition temperature of from 0° C. to 50° C. and a zeta potential lying within the ranges −40 mV to −5 mV and +5 mV to +45 mV. The microparticles have enhanced substantivity to hair, resulting in a longer-lasting fragrance.

Processes for preparing such microcapsules are also described, as are perfuming compositions and consumer products including the capsules, in particular, perfumed consumer products in the form of home care or personal care products.

A core-shell microcapsule comprising a core containing a functional ingredient and a shell surrounding or at least partially surrounding said core, the shell comprising a thermosetting resin formed by the reaction of shell-forming monomers comprising a polyamine and a material comprising a plurality of olefinic double bonds capable of reacting with the polyamine.

Described herein is a perfuming composition including at least two pro-perfume compounds selected from: a pro-perfume compound releasing a perfume compound upon exposure to light, a pro-perfume compound releasing a perfume compound upon exposure to air/oxygen, a pro-perfume compound releasing a perfume compound upon exposure to heat, a pro-perfume compound releasing a perfume compound upon exposure to moisture, and a pro-perfume compound releasing a perfume compound upon exposure to enzymes. Also described herein is a perfumed consumer product including such a perfuming composition, as well as the use of the perfuming composition for improving, enhancing, conferring, and/or modifying the fragrance impression and/or fragrance intensity of a consumer product.

The present invention relates to fragrance mixtures comprising or consisting of a compound of formula (I) and one or more fragrances having a green and/or flowery scent. The invention further provides methods for producing a fragrance mixture according to the invention and methods for enhancing and/or modifying a green and/or flowery scent by mixing a compound of formula (I) with one or more fragrances having a green and/or flowery scent. Moreover, the present invention provides perfumed products comprising a fragrance mixture of the present invention and methods for producing a perfumed product as well as a use of the compound of formula (I) to enhance and/or modify a green and/or flowery scent.

The invention relates to a unit dose sachet comprising a perfume composition, wherein the perfume composition is a gel which comprises i) 0.2 to 2.0% by weight of a gelling agent selected from acrylates/C.sub.10-C.sub.30 alkyl acrylate cross polymers; ii) 60.0 to 75.0% by weight of a cosmetically acceptable alcohol; iii) 0.8 to 9.0% by weight of a fragrance composition having a liquid bulk specific gravity 20/20° C. of 0.97 to 1.08, a refractive index at 20° C. of 1.45 to 1.53 and a flash point of 100° C. to 1000° C.; iv) 0.5 to 1.5% by weight of a stabilizer; and v) 0.5 to 2.4% by weight of a solubilizer, vi) water up to 100% by weight, wherein the composition has a viscosity of 17,500 to 24,200 cps, and wherein the ratio of fragrance composition:gelling agent:alcohol is from 1:0.06:6 to 1:0.16:12.5.
