  • Patent number: 4260508
    Abstract: A powdered sodium percarbonate composition is provided which exhibits significantly improved percarbonate stability during storage. The sodium percarbonate is stabilized by a phosphate containing compound such as sodium tripolyphosphate or sodium orthophosphate. The powdered sodium percarbonate composition is useful as a powder bleach and preferably comprises a separation resistant bleach composition in the form of a plurality of particles, substantially each particle including sodium carbonate, sufficient sodium percarbonate to provide from about 1 to about 6 weight percent available oxygen, and sufficient of the phosphate containing stabilizer to retard decomposition of the percarbonate.

  • Patent number: 4259217
    Abstract: Laundry detergent compositions containing no phosphate or low levels of phosphate materials and specific mixtures of selected nonionic surfactants and selected cationic surfactants are disclosed. The nonionic/cationic surfactant mixtures are formulated to have "cloud point" characteristics and, preferably, reduced cationic monomer concentrations as defined herein. These compositions are unusually effective in removing greasy and oily soils and body soils from fabrics; they are also effective in the removal of particulate soils. A process is disclosed for laundering fabrics using compositions containing nonionic surfactants and cationic surfactants.

  • Patent number: 4257906
    Abstract: The trialkali metal salts of nitrilotriacetate are well known detergent builders. However, when hypochlorite bleach is added to the wash water it can oxidize the soluble uncomplexed nitrilotriacetate with the resultant loss of the beneficial effects of the use of such salts as a builder. Now, a method has been developed of protecting the desirable builder properties of the trialkali metal nitrilotriacetate in an aqueous solution containing active chlorine which comprises adding to the nitrilotriacetate a sufficient amount of trialkali metal imidodisulfate to protect at least some of the nitrilotriacetate from damage by the chlorine.

  • Patent number: 4254199
    Abstract: There is described an electrophotographic imaging method which utilizes an imaging member comprising a substrate, a layer of a charge carrier injecting material, a layer of a charge carrier transport material, a layer of a photoconductive charge carrier generating material and an electrically insulating overcoating layer. In operation, the member is charged a first time with electrostatic charges of a first polarity, charged a second time with electrostatic charges of a polarity opposite to said first polarity in order to substantially neutralize the charges residing on the electrically insulating surface of the member and exposed to an imagewise pattern of activating electromagnetic radiation whereby an electrostatic latent image is formed. The electrostatic latent image may be developed to form a visible image which may be transferred to a receiver member. Subsequently the imaging member may be reused to form additional reproductions after erasure and cleaning steps are carried out.
