METHOD FOR PRODUCING A NON-POROUS COMPOSITE MATERIAL THAT IS WATER-ABSORBENT AND LIPID-ABSORBENT FOR ACTIVE LIQUID COMPOSITIONS

NºPublicación: US2018265649A1 20/09/2018

Solicitante:
AB7 INNOVATION S A S U [FR]

Resumen de: US2018265649A1

The subject matter of the present invention is a method for producing a biodegradable, non-porous composite material made water-absorbent and/or lipid-absorbent, used for obtaining diversely shaped solid objects to be subsequently loaded with active liquid hydrophilic and/or lipophilic compositions comprising at least one active ingredient intended to be delivered into an environment in a controlled and continuous manner. The absorption of the hydrophilic and/or lipophilic composition by said objects is achieved using a network of hydrophilic and/or lipophilic wicks formed in the non-porous material by the co-absorbents. Said method according to the invention is discontinuous, insofar as it comprises storage steps which are steps involving partial interruption of the process insofar as the intermediate products are storable. Indeed, the storage of the fine powder or meal obtained in the first part of the method requires that the maturation thereof allows the distribution of liquid substances in the mass of powder. The storage of the solid objects obtained promotes a flexible management of later operations for their loading with at least one active liquid composition which takes account of the intended purpose of the active objects. Said objects can be used in agriculture, feed supply, veterinary medicine, animal husbandry, animal feed, hygiene, ambient air treatments, perfumery or in the maintenance of green spaces.
