MICROENCAPSULATION OF OXYGEN LIBERATING REACTANTS
There is provided a composition for the delivery of oxygen having microencapsulated peroxide and microencapsulated catalyst that liberate oxygen upon sufficient contact with each. The components may be stored separately or together until use. Upon mixing, oxygen is liberated. The composition can be used for wound healing or for cosmetic applications to deliver oxygen to the skin to help skin elasticity and retard the effects of aging.
1 . A composition for the delivery of oxygen comprising microencapsulated peroxide and microencapsulated catalyst that liberate oxygen upon contact with each other.
2 . The composition of claim 1 wherein said peroxide and/or catalyst is encapsulated with PLGA in the presence of a solvent upon spraying through a nozzle.
3 . The composition of claim 2 wherein said microencapsulated peroxide and/or encapsulated catalyst have a size between 2 microns and 1 mm.
4 . The composition of claim 3 wherein said microencapsulated peroxide and/or encapsulated catalyst have a size between 50 and 100 microns.
5 . The composition of claim 1 wherein said microencapsulated peroxide and microencapsulated catalyst are stored separately until use.
6 . The composition of claim 1 wherein said microencapsulated peroxide and microencapsulated catalyst are stored together until use.
7 . The composition of claim 1 wherein said peroxide comprises hydrogen peroxide.
8 . The composition of claim 1 wherein said catalyst is selected from the group consisting of catalase, manganese dioxide and a base.
9 . The composition of claim 1 further comprising natural or synthetic polymers, moisturizers, humectants, viscosity modifiers, emollients, texture enhancers, UV blocking agents, colorants, pigments, ceramics (fumed silica, titanium dioxide, natural and synthetic clays), antioxidants, fragrances and combinations thereof.
