Abstract
Provided are dispersions which comprise more than about (40) percent by weight of an organic peroxide which is normally solid, an effective dispersing amount of a pharmaceutically acceptable dispersing agent and water. The water and about (40) percent or more peroxide forms a paste. Addition of the dispersing agent/surfactant to a non-flowing organic paste resulted in the formation of a shear thinning aqueous dispersion. The aqueous dispersions can also contain optional components such as thickening agents and anionic emulsifiers.
