Abstract: A microcapsule composition, wherein the shell of the microcapsules comprises at least one polyurea which contains at least one permanent cationic group, which is covalently bonded to the shell and the core comprises at least one perfume ingredient, and wherein the shell of the microcapsules does not contain guanidinium groups.

Abstract: Encapsulated perfume composition comprising at least one aminoplast core-shell microcapsule dispersed in a suspending medium, the microcapsule comprising a perfume-containing core encapsulated in a shell, said shell comprising a network of cross-linked aminoplast resin, wherein 75-100% of the resin comprises 50-90%, preferably from 60-85%, of a terpolymer and from 10-50%, preferably from 10-25%, of a polymeric stabilizer; the terpolymer comprising: (a) from 20-35 wt %, preferably 22-30% by weight of moieties derived from at least one triamine, (b) from 30-60 wt %, preferably 40-55% by weight of moieties derived from at least one diamine, (c) from 20-35 wt %, preferably 22-30% by weight of moieties derived from the group consisting of alkylene and alkylenoxy moieties having 1 to 6 methylene units, preferably 1 to 4 methylene units and most preferably 1 methylene unit.

Abstract: An encapsulated perfume composition comprising at least one perfume-containing aminoplast core-shell microcapsule dispersed in an aqueous suspending medium, the microcapsule being characterized in that it bears a positive charge.

Abstract: An encapsulated perfume composition in the form of a slurry comprising one or more core-shell capsules, dispersed in an aqueous dispersing medium, wherein the core contains a perfume and the shell contains a polyurea resin, and wherein the capsules are in the form of a stable suspension having a viscosity of up to 3000 centipoise, and more particularly about 150 to 3000 centipoise when measured on a rheometer, using rotating disks at a shear rate of 21 s?1 at a temperature of 25° C.

Abstract: 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,

Abstract: Core-shell capsules suitable for perfuming a consumer product comprising a polymeric shell surrounding and encapsulating a perfume-containing oil core, the mean diameter (D50) of which capsules is about 5 to 250 microns and which capsule is adapted to be ruptured to release perfume contained in the core under a rupture force of less than 2 milli Newtons (mN).

Abstract: Microcapsules comprising a core of fragrance and a shell of aminoplast polymer, the composition of the shell being from 75-100% of a thermoset resin comprising 50-90%, preferably from 60-85%, of a terpolymer and from 10-50%, preferably from 10-25%, of a polymeric stabilizer; the terpolymer comprising: (a) from 20-60%, preferably 30-50% of moieties derived from at least one polyamine, (b) from 3-50%, preferably 5-25% of moieties derived from at least one aromatic polyol; and (c) from 20-70%, preferably 40-60% of alkylene or alkylenoxy moieties having 1 to 6 methylene units, preferably 1 to 4 methylene units and most preferably 1 methylene unit; the microcapsules additionally optionally comprising up to 25%, preferably up to 10% of a cationic polymer. The microcapsules are useful for the storage and dissemination of fragrance in various products, such as laundry products and fabric care products.
