ABSTRACT:
An oxygen generating microencapsulated composition includes an oxygen generating core material and a coating which is water swellable. When exposed to water, the coating ruptures in an exfoliating manner, exposing the core material to water and thereby generating oxygen. The rate of oxygen release from the microcapsule can be controlled by altering wall continuity, thickness, capsule diameter, and coating characteristics. In other embodiments, combustion resistant materials are included in the wall material.
