Abstract
(DE)
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von mehrschichtigen Mikrokapseln, insbesondere von mehrschichtigen Duft- oder Riechstoffkapseln, welche eine verbesserte Stabilität und Duft- bzw. Riechstofffreisetzung gegenüber Kapseln des Stands der Technik aufweisen. Darüber hinaus betrifft die vorliegende Erfindung mehrschichtige Mikrokapseln, umfassend mindestens einen hydrophoben Duft- oder Riechstoff, die nach dem erfindungsgemäßen Verfahren erhältlich sind. In einem weiteren Aspekt betrifft die hierin beschriebene Erfindung mehrschichtige Mikrokapsel, umfassend einen Kern umfassend mindestens einen hydrophoben Duft- oder Riechstoff, und eine Kapselhülle. Außerdem betrifft die vorliegende Erfindung die Verwendung der mehrschichtigen Mikrokapseln und Suspensionen aus den mehrschichtigen Mikrokapseln als Bestandteil von Waschmitteln, Weichspülern, Reinigungsmitteln, Scent Boostern (Duftverstärkern) in flüssiger oder fester Form, Kosmetika, Körperpflegeprodukten, Agrarprodukten oder pharmazeutischen Produkte.
(EN)
The present invention relates to a method for producing multi-layered microcapsules, in particular multi-layered fragrance capsules or odorant capsules, which have improved stability and release of fragrance or odorant in comparison with capsules from the prior art. The present invention additionally relates to multi-layered microcapsules which comprise at least one hydrophobic fragrance or odorant and are obtainable by the method according to the invention. In a further aspect, the invention described herein relates to multi-layered microcapsules comprising a core, comprising at least one hydrophobic fragrance or odorant, and a capsule shell. In addition, the present invention relates to the use of the multi-layered microcapsules and suspensions of the multi-layered microcapsules as a component of detergents, fabric softeners, cleaning agents, scent boosters (fragrance enhancers) in liquid or solid form, cosmetics, bodycare products, agricultural products or pharmaceutical products.

La présente invention concerne un procédé de fabrication de microcapsules multicouches, en particulier de capsules de substances parfumantes ou odorantes multicouches, qui présentent une stabilité et une libération de substances parfumantes ou odorantes améliorées par rapport aux capsules selon l'état de la technique. La présente invention concerne en outre des microcapsules multicouches comprenant au moins une substance parfumante ou odorante hydrophobe pouvant être obtenues par le procédé selon l'invention. Selon un autre aspect, la présente invention concerne des microcapsules multicouches comportant un noyau comprenant au moins une substance parfumante ou odorante hydrophobe, ainsi qu’une enveloppe de capsule. La présente invention concerne par ailleurs l’utilisation des microcapsules multicouches et de suspensions à base des microcapsules multicouches comme ingrédients de détergents, d'assouplissants, de produits de nettoyage, de renforçateurs de parfum sous forme liquide ou solide, de cosmétiques, de produits de soin corporel, de produits agricoles ou de produits pharmaceutiques.
