  • Patent number: 5296239
    Abstract: Peracetic acid compositions containing at least one thickening agent and optionally a stabilizer chosen from sequestering agents, free-radical scavengers and mixtures containing two or more of these products.The preferred compositions are obtained by successively incorporating at least one stabilizer and then at least one thickening agent.These compositions are especially capable of being employed for the disinfection of large bulks which are difficult to immerse and of nonhorizontal surfaces, and for detergency or bleaching at low temperature.

  • Patent number: 4428914
    Abstract: A process for the production of sodium percarbonate granules comprises the steps of impregnating seeds with an aqueous phase or phases containing sodium percarbonate or its precursors, and evaporating water from the impregnated seeds in a fluidized bed dryer in the presence of at least one condensed phosphate.

  • Patent number: 4329244
    Abstract: Particles of peroxygenated compounds stabilized with polymers, possessing hydroxyl groups and carboxyl groups, which contain monomeric units of the formula ##STR1## where R.sub.1 and R.sub.2 represent hydrogen or an alkyl group containing from 1 to 3 carbon atoms and where M represents hydrogen, an alkali metal atom or an alkaline earth metal atom M-. The particles can be used in compositions having a bleaching action.

  • Patent number: 4321301
    Abstract: Process for stabilizing particles of peroxygenated compounds by coating by means of a solid coating agent comprises applying a coating agent which contains at least one boron compound from metaboric acid, orthoboric acid and tetraboric acid.

  • Patent number: 4215097
    Abstract: Abrasion resistant granules of sodium perborate monohydrate are made by introducing an aqueous solution containing hydrogen peroxide and an aqueous solution containing sodium metaborate simultaneously into a fluidized bed dryer which contains seeds of a size smaller than that of the desired granules. At least one surface active agent is introduced into at least one of the aqueous solutions containing hydrogen peroxide and sodium perborate. Water present in the aqueous solutions is evaporated by fluidization gas which is introduced into the fluidized bed dryer. The process produces, in one stage, granules of sodium perborate monohydrate having a high rate of dissolution, good flowability, abrasion resistance, and other desirable properties.

  • Patent number: 4185960
    Abstract: Superoxidized solid sodium perborate contains more than 17 wt.% active oxygen and less than 1.4 atoms hydrogen per active oxygen atom. The superoxidized solid sodium perborate in particle form is prepared by simultaneously introducing, into a fluidized bed dryer containing seeds of dimensions smaller than those of the perborate particles which are to be obtained, an aqueous solution containing hydrogen peroxide in concentrations above 30 wt.% and an aqueous solution containing sodium metaborate in such quantities that the molar ratio between the hydrogen peroxide and the sodium metaborate introduced into the fluidized bed is above 1.12. The water present in the aqueous solutions is evaporated by means of a fluidizing gas.

    Abstract: Abrasion resistant granules of sodium perborate monohydrate are made by introducing an aqueous solution containing hydrogen peroxide and an aqueous solution containing sodium metaborate simultaneously into a fluidized bed dryer which contains seeds of a size smaller than that of the desired granules. Water present in the aqueous solutions is evaporated by fluidization gas which is introduced into the fluidized bed dryer. The process products, in one stage, granules of sodium perborate monohydrate having good flavorability, abrasion resistance, and other desirable properties.

  • Patent number: 4105827
    Abstract: Particulate peroxygen compounds selected from alkali metal percarbonates, perpyrophosphates, pertripolyphosphates and peroxymonosulphates are stabilized by coating the particles with a mixed salt selected from sesquicarbonate having the formula Na.sub.2 CO.sub.3.NaHCO.sub.3.2H.sub.2 O and mixed compounds obtained by crystallization of sodium sulfate and sodium carbonate of formula Na.sub.2 SO.sub.4.nNa.sub.2 CO.sub.3 where n is a number from 0.3 to 3.

  • Patent number: 3992317
    Abstract: Particulate peroxygen compounds such as sodium percarbonate are coated with a copolymer of vinylidene chloride and another copolymerizable monomer. These coated compounds can be used in detergent mixtures. The coating of peroxygen compound with such films protect the compound from the effect of decomposition by wet air during storage while it permits liberation of the peroxygen compound in an aqueous washing solution.
