A method of preparing a microcapsule composition include the steps of: (a) providing a microcapsule formed of an encapsulating polymer having a primary or secondary amine group. (b) providing a deposition agent having a reactive group, and (c) forming a covalent bond between the primary or secondary amine group and the reactive group to graft the deposition agent to the encapsulating polymer. Also disclosed are consumer products containing these microcapsules.

Surface modified microcapsules

Disclosed are microcapsule compositions having a microcapsule that contains a microcapsule core and a microcapsule shell encapsulating the microcapsule core. The microcapsule has a particle size of 1 micron to 100 microns in diameter. The microcapsule core contains an active material. The microcapsule shell is formed of at least three moieties, in which a first moiety is derived from a polygalactomannan, a second moiety is derived from a polyisocyanate, and a third moiety is derived from a multi-functional aldehyde or a tannic acid.

Guar gum microcapsules

Microcapsule compositions as disclosed comprising a microcapsule dispersed in an aqueous phase. The microcapsule has a microcapsule core and a microcapsule wall encapsulating the microcapsule core. The microcapsule core contains an active material. The microcapsule wall is formed of a polymeric network comprising a first moiety derived from a protein, and a second moiety derived from a multi-functional electrophile. Also disclosed are preparation methods and consumer products containing the microcapsule compositions.

Protein microcapsules and method of preparing the same

A microcapsule composition containing microcapsules coated with a deposition protein, e.g., a protein-silanol copolymer, a protein-silane copolymer, a protein-siloxane copolymer, or a cationically modified protein, is provided as is a method for making the microcapsule composition and using the microcapsule composition in consumer products, in particular rinse-off consumer product.

Compositions containing microcapsules

Disclosed are microcapsules each having a microcapsule core and a microcapsule wall encapsulating the microcapsule core. The microcapsule core contains an active material and the microcapsule wall contains hydroxyethyl cellulose moieties. Also disclosed are preparation method and consumer products containing the microcapsules.

Hydroxyethyl cellulose microcapsules

Disclosed are microcapsule compositions and their preparation methods. The microcapsule composition has a microcapsule dispersed in an aqueous phase. The microcapsule has a microcapsule core and a microcapsule wall encapsulating the microcapsule core. The microcapsule core contains an active material selected from the group consisting of a fragrance, cosmetic active, malodor counteractant, and combinations thereof. The microcapsule wall is formed of a polymeric network comprising of at least three moieties: (i) a first moiety derived from a chitosan, (ii) a second moiety derived from a polyisocyanate, and (iii) a third moiety derived from a polyphenol. Also disclosed are consumer products contain such a microcapsule composition.

Microcapsule compositions

A microcapsule composition containing microcapsules is provided as is a method for making the microcapsule composition and using the microcapsule composition in consumer products.

Compositions containing microcapsules coated with deposition proteins

A malodor counteracting composition contains a malodor counteractant that is capable of neutralizing a malodor and a stabilizer that is capable of decreasing or preventing self-polymerization of the malodor counteractant. The malodor counteractant has a backbone and one or more reactive end groups that are covalently attached to the backbone, the backbone has a molecular weight of 100 to 50,000 Daltons, and the one or more reactive end groups each have an &#x3b1;,&#x3b2;-unsaturated carbonyl group. Also disclosed are consumer, industrial or textile products containing the malodor counteracting composition and methods of neutralizing malodor using the composition.

Malodor counteracting compositions

The present application relates to perfume delivery systems and consumer products comprising perfume delivery systems and or perfume raw materials, as well as processes for making and using such perfume delivery systems and consumer products.

Perfume systems

A polymeric encapsulated fragrance is disclosed which is suitable for use in personal care and cleaning products. In a preferred embodiment of the invention the fragrance is encapsulated by a first polymer material to form a fragrance encapsulated polymer, the polymer encapsulated shell is then coated with a cationic polymer, preferably a terpolymer composed of methacrylamidopropyl trimethyl ammonium chloride, acrylamide and acrylic acid.

Terpolymer-coated polymer encapsulated active material

The present invention is a fragrance containing capsule composition dispersed into a lyotropic liquid crystalline surfactant phase as well as a consumer product base containing the same.
