Hair lightening composition comprising hydrogen peroxide, a peroxygenated salt, a carbonate and at least one polyphosphorus derivative

The present disclosure relates to a composition for lightening keratin fibres, comprising (a) hydrogen peroxide; (b) one or more carbonates and/or one or more carbonate-generating systems in a content of greater than or equal to 0.2%, relative to the weight of the composition, (c) one or more polyphosphorus derivatives, in a total content of greater than or equal to 0.5% by weight, relative to the total weight of the composition, and (d) one or more peroxygenated salts, said polyphosphorus derivative(s) being different from said peroxygenated salt(s). The pH of the composition is less than or equal to 10. The present disclosure also relates to a process of using the composition for lightening keratin fibres, and a device comprising the composition.
