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.

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.

The invention provides methods for the preparation of particles including one or more agents, e.g., therapeutic or diagnostic agents. The particles can be formed by creating droplets of a first liquid, e.g., including an agent, and removing the first liquid, e.g., through its dispersal in a second liquid and/or evaporation, to solidify the droplets. Advantageously, the process of forming the particles does not significantly alter the structure or activity of the agents and may enhance the stability of the agents. For example, the particles may be stored for long periods of time without significant loss of activity, and in some embodiments, without the need for refrigeration. These particles may be used to generate stabilized pharmaceutical compositions for storage or other logistical purposes, pharmaceutical suspensions, pharmaceutical powder formulations (e.g., inhalable powders, injectable powders), creams or other topical pastes, nutraceuticals, or cosmetics.

A composite material for gas capture, notably CO.sub.2 capture and storage. The composite material includes a mixture of a solid or liquid reactive filler and a gas-permeable polymer such that the reactive filler forms micron-scale domains in the polymer matrix.

Described herein is a new process for the preparation of polysuccinimide derivatives-based core-shell microcapsules. Also described are microcapsules, as well as perfuming compositions and consumer products including these microcapsules, in particular perfumed consumer products in the form of home care or personal care products.

The invention relates to the field of protecting plants against pests, and more particularly to a method of protecting plants against pests, which can be used for industrial and scientific purposes, in agriculture, horticulture and forestry. The method of protecting plants against pests according to the present invention comprises applying a biologically active preparation pre-activated in an aqueous medium to a plant, the preparation comprising microcontainers and a biological insecticide, wherein the microcontainers are made from a polymeric material in the form of a hollow receptacle with at least one opening, via which the biological insecticide is placed inside the microcontainers. The invention also provides a microcontainer and a preparation for realisation of the stated method. Furthermore, the invention provides methods for producing a microcontainer and the aforementioned preparation.

Fabrication of functional polymer-based particles by crosslinking UV-curable polymer drops in mid-air and collecting crosslinked particles in a solid container, a liquid suspension, or an air flow. The particles can contain different phases in the form or layered structures that contain one to multiple cores, or structures that are blended with dissolved or emulsified smaller domains. A curing system produces ultraviolet rays that are directed onto the particles in the jet stream from one side. A reflector positioned on other side of the jet stream reflects the ultraviolet rays back onto the particles in the jet stream.

Described herein is solid scent booster composition including: solid carrier, granulated powder including particles made of: a) a water soluble polymer matrix, b) an oil phase including a perfume dispersed in the polymer matrix, the oil being at least partly encapsulated in microcapsules, wherein granulated powder includes up to 30% by weight of encapsulated oil based on the total weight of the powder.

A method of manufacturing a triple capsule includes supplying an interior material, an intermediate film material, and an exterior film material; discharging a triple molding body by receiving the interior material, the intermediate film material, and the exterior film material through a nozzle mount and performing coextrusion on the interior material, the intermediate film material, and the exterior film material through a triple nozzle in which a first nozzle discharging the interior material, a second nozzle discharging the intermediate film material, and a third nozzle discharging the exterior film material are arranged concentrically; and forming the triple capsule by circulating a coolant and cooling the triple molding body.
