Abstract

PARTICULAS DE NUCLEO SOLIDO ENCAPSULADAS EN UN SOLO REVESTIMIENTO DE CERA DE PARAFINA Y UNA PEQUEÑA CANTIDAD DE UN ADITIVO DE CERA, TENIENDO LA CERA UN PUNTO DE FUSION DE UNOS 40 A UNOS 50 (GRADOS) C. EL REVESTIMIENTO DE PARAFINA PUEDE CONTENER DE UN 20 A UN 90% EN PESO DE LA PARTICULA Y PUEDE TENER UN GROSOR DE 100 A 1.500 MICRAS. EL REVESTIMIENTO PROPORCIONA UNA ESTABILIDAD MEJORADA Y PROLONGA EL TIEMPO EN QUE LAS PARTICULAS ENCAPSULADAS EN EL PUEDEN PERMANECER ACTIVAS EN ENTORNOS ACUOSOS. LA PARTICULA ENCAPSULADA SE HACE A BASE DE PULVERIZAR CERA DERRETIDA SOBRE LA PARTICULAS EN UN LECHO FLUIDIFICADO. LAS COMPOSICIONES DE LIMPIEZA EN POLVO O LIQUIDAS, EN PARTICULAR LOS DETERGENTES LIQUIDOS LAVAVAJILLAS AUTOMATICOS, PUEDEN INCORPORAR DE UN 0,01 A UN 20% EN PESO DE LA COMPOSICION DE LAS PARTICULAS ENCAPSULADAS EN CERA REVESTIDAS.
