Peroxygen compositions of at least one peroxygen compound combined with at least one polyhydric activator compound having at least four carbon atoms, with the carbon atoms having at least one hydroxyl group bonded thereto, or a boron or aluminum derivative thereof. Solutions of at least one activated peroxygen compound prepared by dissolving in a common solvent therefor at least one peroxygen compound and at least one of the polyhydric activator compounds of the invention. Methods for preparing activated peroxygen compounds by dissolving in a common solvent at least one peroxygen compound and at least one of the polyhydric activator compounds of the invention. Methods for cleaning or bleaching substrates in need thereof by contacting the substrate with a solution of at least one activated peroxygen compound prepared by dissolving in a common solvent at least one peroxygen compound with at least one of the polyhydric activator compounds of the invention.
A peroxygen composition comprising:
A solution comprising an activated peroxygen compound prepared according to a process comprising dissolving in a common solvent therefor, at least one peroxygen bleaching compound selected from the group consisting of peroxyacids and alkali metal peroxygen bleaching compounds and at least one polyhydric activator compound, substantially free of ester or ether hydroxyl group derivatives, said polyhydric activator compound having at least four carbon atoms, each of said carbon atoms having at least one hydroxyl group bonded thereto, wherein said polyhydric activator compound is uncomplexed or in the form of a metal complex, said metal being selected from the group consisting of boron and aluminum.
A peroxygen composition comprising:
A solution comprising an activated peroxygen compound prepared according to a process comprising dissolving in a common solvent therefor, at least one peroxygen bleaching compound and at least one polyhydric activator metal complex substantially free of ester or ether hydroxyl group derivatives, said polyhydric activator metal complex having at least four carbon atoms, each of said carbon atoms having at least one hydroxyl group bonded thereto, wherein said metal is selected from the group consisting of boron and aluminum.
A peroxygen bleaching composition comprising:
A solution comprising an activated peroxygen compound prepared according to a process comprising dissolving in a common solvent therefor, at least one peroxygen bleaching compound and at least one polyhydric activator compound, substantially free of ester or ether hydroxyl group derivatives, said polyhydric activator compound being selected from the group consisting of disaccharides and invertates thereof, pentaerythritol, monosaccharides, sugar alcohols and the internal anhydrides of sugar alcohols, wherein said polyhydric activator compound is uncomplexed or in the form of a metal complex, said metal being selected from the group consisting of boron and aluminum.
