Title (EN) ENCAPSULATED MATERIAL WITH CONTROLLED RELEASE
(FR) SUBSTANCE ENCAPSULEE A LIBERATION REGULEE
Abstract:
(EN) An encapsulated material is described of which at least a part of the material is kept encapsulated during heat treatment in an aqueous environment and is released during cooling after a heat treatment. The material is encapsulated in a layer of a hydrophobic film-forming material and a layer of a material having a low critical solution temperature (LCST) below the treatment temperature. The layer containing the hydrophobic material may be situated inside the layer having the LCST and have a melting point below the LCST, but it may also be situated outside the layer having the LCST and have a melting point above the LCST of said layer. Said layers may also be applied together.
(FR) Cette invention se rapporte à une substance encapsulée, dont une partie au moins est maintenue encapsulée pendant un traitement thermique dans un milieu acqueux et est libérée pendant une opération de refroidissement après le traitement thermique. Cette matière est encapsulée dans une couche d'un matériau filmogène hydrophobe et dans une couche d'un matériau ayant une température de solution critique basse (LCST) inférieure à la température de traitement. La couche contenant le matériau hydrophobe peut être situés à l'intérieur de la couche ayant la température LCST et comporter un point de fusion inférieur à la température LCST, mais elle peut également être placée à l'extérieur de la couche ayant la température LCST et comporter un point de fusion supérieur à la température LCST de cette couche. Lesdites couches peuvent également être appliquées ensemble.
