Title
(EN) PERFUME MICROENCAPSULATION
(FR) MICROENCAPSULATION DE PARFUM
Abstract
(EN)
According to the invention, a core-shell microcapsule is provided comprising a cross-linked polymeric shell encapsulating a perfume-containing core, wherein the cross-linked polymeric shell is the reaction product of a functionalized polysiloxane, a polyisocyanate and a polyamine and wherein the functionalized polysiloxane comprises a polysiloxane backbone, one or more ethoxylated alcohol side chains and one or more substituted or unsubstituted alkyl or aliphatic cycloalkyl side chains.
(FR)
Selon l'invention, une microcapsule à noyau et enveloppe comprend une enveloppe polymère réticulée encapsulant un noyau contenant du parfum, l'enveloppe polymère réticulée étant le produit de réaction d'un polysiloxane fonctionnalisé, un polyisocyanate et une polyamine et le polysiloxane fonctionnalisé comprenant un squelette de polysiloxane, une ou plusieurs chaînes latérales d'alcool éthoxylé et une ou plusieurs chaînes latérales d'alkyle ou de cycloalkyle aliphatique substitués ou non substitués.
