Abstract
Sodium carbonate peroxide stabilized against loss of its active oxygen content is prepared by incorporating into sodium carbonate peroxide an ethylene oxide-derivative stabilizing agent selected from the group consisting of polyethylene glycol, polyethoxy fatty acid tertiary amines, diamines and quaternary ammonium salts thereof, N,N-polyethoxy fatty acid amides and polyethoxy fatty acid esters and recovering the sodium carbonate peroxide as a dry, free-flowing solid.
