Abstract
A method of increasing the stability ofo/w emulsions and providing a potential additional barrier to drug release from the oil droplets is described. Diacryloyl derivatives of non-ionic block copolymers (poloxamers) have been used to stabilise isopropyl myristate in water emulsions. Cross-linking of these stabilisers at the oil-water interface produces a polymeric region which increases the stabilityo/w emulsions to centrifugation and of thew/o emulsions to creaming.
