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.

Abstract: A liquid substantially non-aqueous cleaning or conditioning composition containing a surfactant or a conditioning active ingredient, a content in water which is not above 10% by weight, relative to the total weight of the composition, and a fragrance encapsulated in aminoplast type microcapsules. The compositions of the invention, in the form of fabric detergents or softeners, are particularly stable during storage and have an improved olfactive impact on fabrics.

Abstract: The present invention relates to a perfuming ingredient for body-care, detergents or softeners type consumer products that is made of microcapsules having a mean diameter of >1 to 500 ?m with a guanidine-based polyurea or polyurea/polyurethane wall that contain a perfume and to the products that contain such perfuming ingredients and microspheres.

Abstract: Polymeric micro- and nano-capsules formed of a spherical single hydrophobic polymer, chemically functionalised at their surface so as to comprise hydrophilic moieties thereon are disclosed. The capsules are susceptible of absorbing a perfume and of being optionally coated with an amphiphilic copolymer. They allow the preparation of perfume delivery systems, which provide a slow release of perfuming materials while improving the substantivity of the perfume on a substrate.

Abstract: The present invention relates to a basically spherical hyperbranched block copolymer having an internal hydrophobic block and an external hydrophilic block. Within the spherical copolymer, the hydrophobic block constitutes a hydrophobic layer, suitable to associate or encapsulate hydrophobic bioactive agents, while the hydrophilic block provides an outer layer, which is suitable to render the copolymer soluble or dispersible in aqueous solutions. Also claimed is a method for preparing the copolymer, which is suitable to encapsulate fragrances, flavours, drugs, agrochemicals, for example.

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.
