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.

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

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.
