Abstract: The polymeric nanoparticles including olfactive components have a glass temperature of >50° 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.

Abstract: A method of making a granulated composition that comprises frangible microcapsules containing at least one active ingredient, such as a fragrance, comprising the application of discrete droplets of an aqueous slurry of the microcapsules on to a non-fluidised bed of powdered material, and then drying, the powdered material having a surface tension as defined by an initial contact angle of slurry with powder of at least 40°, which contact angle does not change by more than 10% within the first 3 seconds of application of slurry to powder material. The granulates made by this method are unusually resilient and can withstand rough treatment (for example, during manufacture of products in which they are incorporated), yet can readily release their contents when required. They are also able to be electrically charged.
