Abstract

Una microperla que tiene un nucleo de matriz que comprende una matriz hidrofila y gotas de material activo retenidas en la misma y una capa secundariaadyacente a la superficie exterior del nucleo de la matriz. La capa secundaria puede estar complejad a ionicamente o ligada por hidrogeno a la superficie delnucleo de la matriz. Las composiciones que comprenden las microperlas suspendidas en solucion pueden ser rociadas. La microperlas de la invencion pueden sercontroladas exponiendo las microperlas a mucha o poca humedad o humectacion.
