Abstract: The present invention relates to water-dispersible core-shell microcapsules essentially free of formaldehyde. In particular it concerns core-shell microcapsules having a shell obtained by reacting polyisocyanates or polyoxirans cross-linkers and oligomeric compositions which are the reaction products between a polyamine component and a particular mixture of glyoxal and a C4-6 2,2-dialkoxy-ethanal. The present invention comprises also the invention's core-shell microcapsules as part of a perfuming composition or of a perfuming consumer product.

Abstract: The present invention relates to core-shell microcapsules comprising photolabile 2-oxoacetate pro-fragrance molecules capable of liberating an active molecule such as, for example, an aldehyde or ketone upon exposure to light. 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 aldehydes and/or ketones.

Abstract: The invention relates to a perfume composition that includes a first perfume microcapsule encapsulating a first perfume oil that has a Log T greater than ?2.5 and a cLogP greater than 2.5 and/or a volatility value of at least 30 ?g/l air; and a second perfume microcapsule encapsulating a second perfume oil ingredient that has a LogT less than ?2.5 and a cLogP greater than 2.5 and/or a volatility value of at least 30 ?g/l air. The invention also relates to the use of such mixtures of microcapsules as a perfuming ingredient or perfuming composition for home or personal care products, as well as to the resulting home and body care compositions. Also, a method for increasing shelf life of a home- or personal-care product that contains a perfuming composition which comprises providing the perfume composition as one of the mixtures of microcapsules disclosed herein.

Abstract: Embodiments of various aspects described herein relates to compositions and methods for encapsulation and/or stabilization of odor-releasing substances (e.g., fragrances) and/or flavoring substances in a silk-based material.

Abstract: The present invention relates to polyurea core-shell microcapsules having a polyurea shell comprising the reaction product of a polyisocyanate with guanazole and an amino acid. The invention concerns the capsules themselves as well as perfuming compositions and perfumed articles containing them and a process for producing them.

Abstract: The invention concerns a biodegradable copolymer composition of a polysaccaride backbone grafted with amphiphilic diblock copolymers, as well as a process for the preparation of such composition and a particle suitable for the release of active ingredients made of such a composition.

Abstract: The present invention relates to a process for producing perfume-containing microcapsules with a polyurea wall that can be used in home or personal care products, as well as to the microcapsules themselves and consumer products that include or incorporate these microcapsules. The process of the invention uses a particular colloidal stabilizer in the form of an aqueous solution that includes defined proportions of particular polymers.

Abstract: The present invention relates to the field of perfumery. More particularly, it concerns polyethylene or polypropylene based polymers that have at least one ?-oxy or ?-thio carbonyl moiety capable of liberating a perfuming molecule such as, for example, an ?,?-unsaturated ketone, aldehyde or carboxylic ester. The present invention concerns also the use of such compounds in perfumery as well as the perfuming compositions or perfumed articles that include such compounds.
