Title (EN) SUSTAINED RELEASE BIOCIDAL POWDERS
(FR) POUDRES BIOCIDES A LIBERATION PROLONGEE
Abstract:
(EN) A powder for sustained release of a gas including a hydrophilic core, a hydrophobic layer on an outer surface of the hydrophilic core, and particles in contact with the hydrophobic layer. The hydrophobic layer contains an acid releasing agent. The particles contain an anhydrous material capable of binding with water. The core, the particles, and the hydrophobic layer are substantially free of water, and the core is capable of generating and releasing a gas after hydrolysis of the acid releasing agent.
(FR) L'invention porte sur une poudre permettant la libération prolongée d'un gaz comprenant une âme hydrophile, une couche hydrophobe se trouvant sur une surface externe de l'âme hydrophile et des particules en contact avec la couche hydrophobe. Cette couche hydrophobe contient un agent de libération acide. Les particules contiennent un matériau anhydre capable de se lier avec l'eau. L'âme, les particules et la couche hydrophobe sont pratiquement exemptes d'eau et l'âme est capable de générer et de libérer un gaz après hydrolyse de l'agent de libération acide.
