Disclosed are encapsulated perfume compositions showing improved balance between storage stability in consumer products and perfume diffusivity from intact microcapsules deposited on substrates (so-called pre-rub performance), the compositions comprising a combination of long chain aldehydes having 10 carbon atoms or more and/or tertiary alcohols having 10 carbon atoms or more, in combination with blooming perfume ingredients.

Perfume compositions

Perfume compositions having controlled spatio-temporal olfactory profiles are described. The disclosure also relates also to a method of measuring said spatial-temporal olfactory profiles of said compositions.

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 (logOV) of greater than about 5.5.

Malodor reducing compositions

A dishwasher detergent composition comprising a starch-encapsulated fragrance composition, wherein the starch-encapsulated fragrance composition comprises one or more particles of starch-encapsulated fragrance composition.

Dishwasher detergent fragrance composition

Disclosed are perfume compositions containing perfume ingredients selected on the basis that they are able to be stably incorporated into core-shell microcapsules. Perfume selection rules are based on a molecular descriptor of the electron density distribution within a perfume ingredient&#x2014;RECON VOLTAE. Perfume ingredients having known RECON_VOLTAE values larger than about 1200 Bohr, more particularly larger than 1540 Bohr, and more particularly still larger than about 1750 Bohrare particularly suitable for encapsulation.

Encapsulated perfume compositions

Perfume composition provided in the form of a plurality of dispersed perfume-containing droplets, suspended in an aqueous dispersing medium, said perfume droplets being mono-dispersed and having a diameter of 200 micrometers to 4000 micrometers, wherein said droplets comprise more than 60 wt %, of perfume ingredients, and wherein 25 wt or less of said perfume ingredients are linear or branched alkyl alcohols and/or alkenyl alcohols; 10 wt % or less of the perfume ingredients are aldehydes; and 10 wt % or less of the perfume ingredients have a ClogP less than 2.1.

Perfume composition

A solid, free-flowing composition adapted to deliver fragrance or malodor counteractant in a consumer product that is subjected to actual or potential malodorous influences. The composition comprises a delivery system consisting of a core material surrounded by a fragranced material comprising microdroplets of a dispersed fragrance in a fragrance-encapsulating material, optionally surrounded by a protective coating, and, an external absorbent material in which the fragrance delivery vehicle is dispersed. The composition is effective with respect to animal litters.

Fragrance composition

An encapsulated perfume composition for use in personal care products adapted to be applied to, and left on, the skin or hair of a human or animal subject, said encapsulated perfume composition comprising one or more polyurea capsules having a volume average diameter of 20 to 90 microns, and a capsule shell weight, which is 5 to 40% based on the total weight of the capsules.

Capsule composition

A liquid fragrance composition consisting essentially of:

Organic compounds

A solid, free-flowing composition adapted to deliver fragrance or malodor counteractant in a consumer product that is subjected to actual or potential malodorous influences, comprising: The invention is especially effective with respect to animal litters, especially those for cats.

Disclosed are clear, aqueous perfume compositions which are free of ethanol. There is further provided a perfume composition which is clear, provides a good skin feeling, and good air drying properties on the skin.

Aqueous oil in water micro-emulsions, and product

Aminoplast 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% of a terpolymer and from 10-50% of a polymeric stabilizer; the terpolymer comprising: The capsules are competitive with known aminoplast capsules and have the major advantage that they are formaldehyde-free.

Aminoplast microcapsules containing fragrance

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.

Microcapsules

The polymeric nanoparticles including olfactive components have a glass temperature of &#x3e;50&#xb0; C. They are obtainable by continuously adding a monomer component and an olfactive component to an aqueous solution. The aqueous solution comprises a first initiator and an emulsifier. The added components are distributed in the aqueous solution to obtain reaction mixture while the polymerization of the monomer component is started at the first temperature. The liquid monomer component and the olfactive component are added continuously while a second initiator is added dropwise to the reaction mixture and the first temperature is maintained. After terminating the addition of liquid monomer component and the olfactive component the temperature of the reaction mixture is increased to a second temperature and a third initiator is added dropwise.

Polymeric nanoparticles including olfactive components

A composition comprising a fragrance material consisting of an outer matrix containing components of the fragrance material and disposed within the outer matrix, discrete core particles containing the remaining components of the fragrance material. Components of the fragrance material within the core particles are preferably selected from highly volatile and/or water soluble materials, whereas components of the fragrance material within the outer matrix are preferably selected from relatively low volatile and/or low water soluble materials.
