A pulverulent composition for bleaching human keratin fibers, such as hair, comprising
at least one peroxygenated salt, at least one polymer chosen from nonionic and
anionic amphiphilic polymers, wherein the at least one polymer comprises at least
one fatty chain; and less than 10% by weight of a fatty acid sugar ester comprising
at least one sugar residue and at least one C12-C24 fatty
acid residue. The pulverulent composition is capable of being mixed with at least
one aqueous hydrogen peroxide composition having a titer of not more than 40 volumes
to form stable, homogeneous, bleaching compositions that can be applied precisely
and easily, and can produce a homogeneous bleaching of the hair that does not leave
the hair coarse.
