A nano-particulate composition comprising nano-particulate capsule comprising at least one or more of hydrophobic core material and a polymeric shell comprising homo-polymer or copolymers of at least one ethylenically unsaturated monomers or mixture thereof and having particle size distribution with an average article size in the range of 50 to 1000 nm is provided together with a controlled release delivery system comprising fragrance release delivery system involving said nano-particulate capsule water based emulsion and a process of manufacture thereof. Said delivery system provided is able to protect and release the fragrance in a controlled manner over a period of time. The controlled release fragrance delivery system of the present invention finds advantageous end use and application in fragranced consumer products formulations including water based coating/paint formulations and industrial formulations for use in industries including textile, cosmetics, soaps and detergents, leather industries.

A flavor nanoemulsion. The nanoemulsion contains a plurality of oil droplets, an aqueous phase, and a surfactant system including a polyethoxylated sorbitan fatty acid ester and a lecithin. Also disclosed is a liquid beverage or a liquid beverage concentrate containing the nanoemulsion and a method of preparing the same.

Provided is means of powderizing a liquid component, wherein the powderizing agent contains an oil and/or fat composition, the oil and/or fat composition contains an oil and/or fat component which contains one or more types of XXX-type triglycerides having fatty acid residues X, each with x carbon atoms, at positions 1 to 3 of glycerin, x, the number of carbon atoms, is an integer selected from 10 to 22, and the XXX-type triglyceride is contained at 50% by mass or more relative to a content of the oil and/or fat component being 100% by mass; or the powderizing agent, wherein the oil and/or fat composition is a powder oil and/or fat composition having a loose bulk density of 0.05 to 0.6 g/cm.sup.3, the oil and/or fat component contains a β-type oil and/or fat, and a particle of the powder oil and/or fat composition has a plate shape.

The present invention relates to water-dispersable microcapsules comprising an oil phase, e.g. a perfume, containing a photolabile α-ketoacid or α-ketoester capable of generating a gas upon exposure to light. The gas is able to cause an extension or the breaking of the microcapsule allowing the release of the oil phase and thus increasing the long-lastingness of the odor perception. The present invention concerns also the use of said microcapsules in perfumery as well as the perfuming compositions or perfumed articles comprising the invention's microcapsules to provide a prolonged release of fragrant molecules.
