La invención provee un proceso para la preparación de microcápsulas de aceites esenciales que comprende disolver un di- o poliisocianato en un aceite esencial, emulsionar la mezcla resultante en una solución acuosa que contiene una di- o poliamina, y/o un compuesto di- o polihidroxilado para efectuar el encapsulamiento de dicho aceite esencial a través de polimerización interfacial, por lo cual se forma una película de poliurea y/o poliuretano alrededor de las gotitas de aceite esencial, película que potencia la estabilidad de dicho aceite esencial, reduce su velocidad de evaporación y controla su velocidad de liberación cuando se aplica a un sustrato.The invention provides a process for the preparation of microcapsules of essential oils comprising dissolving a di- or polyisocyanate in an essential oil, emulsifying the resulting mixture in an aqueous solution containing a di- or polyamine, and / or a di-o compound. polyhydroxylated to encapsulate said essential oil through interfacial polymerization, whereby a film of polyurea and / or polyurethane is formed around the essential oil droplets, film that enhances the stability of said essential oil, reduces its speed of evaporation and controls its release rate when applied to a substrate.
Composition, processes for inhibiting a response to ethylene in a plant, for extending the life of a plant and for dispensing a cyclopropene compound to a plant, and article of manufacture.
Degradable film for packaging of fruits and vegetables comprising a polymer matrix based on polyolefin, which incorporates an antimicrobial active agent (biocide or fungicide) of essential oil or said essential oil, and also incorporates degrading agents, and microencapsulation process of said Active antimicrobial essential oil agent, and film preparation method.
Method of producing a microcapsule comprising maintaining a pesticidal compound, a compound and a polyisocyanate, adding the mixture to the water containing a polyol or a polyamide, producing liquid droplets in the water and forming a polyurethane or polyurea film around the droplets ; and microcapsule.
PROCEDURE TO PREPARE A FORMULATION OF S, S-DISEC-BUTIL-O-ETILO (CADUSAFOS), MICROENCAPSULATED, PESTICIATED FORMULATION AND GRANULAR PESTICIDE FORMULATION OBTAINED WITH THE SAME.
