  • Patent number: 6274125
    Abstract: A granulated composition for bleaching hair compresses granules of a pulverulent material which is sodium persulfate, potassium persulfate, ammonium persulfate, sodium perborate, potassium perborate, ammonium perborate, barium peroxide, strontium peroxide and mixtures thereof bound together with propylene glycol having a molecular weight ranging from 200 to 10,000. The binder is present in an amount not exceeding 25 percent by weight of the composition.
    Type: Grant
    Filed: March 25, 1994
    Date of Patent: August 14, 2001
    Assignee: L'Oreal
    Inventors: Jean-Marie Millequant, Caroline Tricaud, Anne Gaboriaud
  • Patent number: 5660190
    Abstract: The invention relates to novel pulverulent cosmetic compositions for bleaching hair, containing at least one oxidizing agent selected from peroxidized compounds, and at least one polymer selected from polyethylene glycol, polypropylene glycol, a derivative of polyethylene glycol, and a derivative of polypropylene glycol, where the polymer is present in an amount of 10 to 27% by weight, the polymer is anhydrous and, at room temperature, both liquid and water-soluble. The invention also relates to a process for the preparation of such compositions and to their use for bleaching hair.
    Type: Grant
    Filed: March 1, 1995
    Date of Patent: August 26, 1997
    Assignee: L'Oreal
    Inventors: Caroline Tricaud, Jean-Marie Millequant, Henri Sebag
  • Patent number: 5650091
    Abstract: Granulated bleaching composition, which may especially be used for bleaching hair, in which the granules have been obtained by granulation of a mixture of its various pulverulent constituents by means of two binders: a first binder chosen from the group formed by polyvinyl alcohol, homo- and copolymers of vinyl-pyrrolidone and their mixtures and a second binder chosen from the group formed by polyalkylene glycols in which the alkylene group is C.sub.2 to C.sub.4 and which have a molecular weight between 200 and 30,000, and their mixtures, the granules having a particle size between 65 .mu.m and 800 .mu.m.
    Type: Grant
    Filed: June 7, 1995
    Date of Patent: July 22, 1997
    Assignee: L'Oreal
    Inventors: Jean-Marie Millequant, Caroline Tricaud, Anne Gaboriaud
  • Patent number: 5622691
    Abstract: Cosmetic compositions for bleaching hair comprising at least one oxidizing agent selected from peroxygen compounds and at least one block and/or random linear polyoxyethylene/polyoxypropylene copolymer, the copolymer being anhydrous and, at room temperature, further being both liquid and soluble in water, and the composition being pulverulent and anhydrous. Bleaching powders that are fine, anhydrous, free-flowing, homogeneous, non-dusty, are perfectly dispersible in hydrogen peroxide and have improved cosmetic properties.

  • Patent number: 5612022
    Abstract: A process for preparing a pulverulent, anhydrous hair bleaching composition comprises mixing in a non-solvent medium at room temperature a dry bleaching powder of a peroxygen compound oxidizing agent and at least one anhydrous block and/or random polyoxyethylene/polyoxypropylene copolymer which is liquid and water-soluble at room temperature.
