Abstract
The use of inorganic nanoparticles to stabilize aqueous hydrogen peroxide solutions is described. The preferred nanoparticles are formed from clays. The use of nanoparticles formed from synthetic smectite clays is particularly preferred. The stabilized hydrogen peroxide solutions may be utilized for various purposes, but are particularly useful as contact lens disinfecting solutions.
