A core shell microcapsule having a liquid core and an outer shell, in which the liquid core comprises solvent and a piroctone compound and the shell comprises polyurea comprising amino sulphonic acid.

A cement composition is provided. The cement composition comprises: a microcapsule and cement. The microcapsule is provided with a core-shell structure having i) a core containing a water-repellent organosilicon material selected from the group consisting of organosilanes, organosilane partial condensation products, and branched siloxane resins, and ii) a shell of a silicon-based network polymer containing a silica unit. The microcapsule is included at 0.01 to less than 0.5 parts by weight per 100 parts by weight of the cement. Thus, it is possible to provide a cement composition that can provide a cured product having high strength, as well as excellent air content stability, substance penetration prevention, drying shrinkage, and freeze-thaw resistance.

An article of manufacture is described comprising the combination of an adjunct material and a delivery particle. The delivery particle comprising a benefit agent core material and a shell encapsulating the core material is described, along with a process for forming such a delivery particle and articles of manufacture. The shell is the reaction product of: i) an isocyanate or acid chloride or acrylate with ii) an amine-containing natural material having free amino moieties, and iii) an α, β-unsaturated compound, the α, β-unsaturated compound forming C—N covalent bonds with the amine moieties of the natural material. The delivery particle of the invention has improved release characteristics, with enhanced degradation characteristics in OECD test method 301B.

The present invention relates to a new process for the preparation of microcapsules. Microcapsules obtainable by said process are also an object of the invention. Perfuming compositions and consumer products comprising said capsules, in particular perfumed consumer products in the form of home care or personal care products, are also part of the invention.

The present disclosure relates to fragrance materials encapsulated within polymeric materials in the form of microcapsules of polymer encapsulated fragrance. The microcapsules are mixed with a water-based binding agent so that a coating forms on the microcapsule in situ, after which the coated microcapsules may be applied to hard surfaces of a product, from which controlled release of the fragrance is provided over time as the product is subjected to normal handling by a user.
