  • Granulated composition based on peroxidized derivatives for bleaching hair and process for the preparation of the said compositions
    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

  • Process for the preparation of a granulated bleaching composition comprising first and second binders
    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
