ABSTRACT:
Non-segregating, pumpable, aqueous organic peroxide compositions comprising from about 10 to 65 weight percent of an organic peroxide are described. The compositions are prepared by forming an aqueous dispersion of the organic peroxide utilizing an emulsifying amount of a surfactant and thereafter mixing the peroxide dispersion with a freezing point depressant (or aqueous solution thereof) selected from the group consisting of polyhydric alcohols containing at least three hydroxyl groups, poly(C.sub.2 -C.sub.3) alkalene glycol having a molecular weight of less than 320, C.sub.4 -C.sub.6 monosaccharides, the halide salts of the alkali metals and magnesium, and mixtures of such compounds. A sufficient amount of the freezing point depressant is used to provide a liquid peroxide composition that is readily pumpable at from 0.degree. C. to -20.degree. C. Organic peroxides described are dialkylperoxydicarbonates, diacylperoxides and peresters.
