MICROCAPSULES

A core-shell microcapsule comprising c) an inner shell encapsulating a benefit agent; and d) an outer shell of crosslinked polysaccharide; crosslinking being effected by means of at least one oligofunctional (meth)acrylate compound. The resulting core-shell microcapsules have a reduced content of ma...

Beschreibung
Zusammenfassung:	A core-shell microcapsule comprising c) an inner shell encapsulating a benefit agent; and d) an outer shell of crosslinked polysaccharide; crosslinking being effected by means of at least one oligofunctional (meth)acrylate compound. The resulting core-shell microcapsules have a reduced content of material derived from non-renewable sources. L'invention concerne une microcapsule cœur-enveloppe comprenant c) une enveloppe interne encapsulant un agent bénéfique ; et d) une enveloppe externe de polysaccharide réticulé ; la réticulation étant effectuée au moyen d'au moins un composé (méth)acrylate oligofonctionnel. Les microcapsules cœur-enveloppe ainsi obtenues présentent une teneur réduite en matériau dérivé de sources non renouvelables.
