Patent

CA 2485953

A coated triggered start product is formed from a particulate core material comprising at least one water soluble active constituent and at least one coating layer applied on the particulate core material. The coating layer causes the product to exhibit "lock-off' type release characteristics whereby release of the active constituent of the core material from the coated product is essentially completely suppressed until release is initiated by application of a trigger material to the coating layer. Processes for preparing and using such triggered start products are also provided.

L'invention concerne un produit enrobé à libération déclenchée, formé à partir d'un matériau d'âme particulaire comprenant au moins un élément actif soluble dans l'eau et au moins une couche d'enrobage appliquée sur le matériau d'âme particulaire. La couche d'enrobage amène le produit à révéler des caractéristiques de libération du type "verrouillé", si bien que la libération de l'élément actif du matériau d'âme du produit enrobé est presque complètement inhibée tant que cette libération n'est pas induite par application d'un matériau de déclenchement sur la couche d'enrobage. L'invention concerne en outre des procédés de préparation et d'utilisation desdits produits enrobés à libération déclenchée.
