Title:
【発明の名称】ポリマー担体組成物の製造方法
Document Type and Number:
Japanese Patent JP2793188
Kind Code:
B2
Abstract:
Polymeric delivery systems for active substances are prepared by suspension polymerization of a porogen and monomer mixture in an immiscible phase, typically an aqueous immiscible phase. By properly controlling the polymerization conditions and percentage of cross-linking, relatively rigid beads are formed having a non-collapsible pore network containing the porogen. The porogen is then extracted from the pore network, and an active substance, such as a UV absorbant, and insect repellant, a steroid, an emollient, or the like, is introduced into the beads.
