Abstract
A new oxidizing agent composition for mixing with oxidation dye pre-cursor compounds, such as developer and coupler substances, to form a ready-to-use dye mixture for dyeing keratin fibers is described. The oxidizing agent composition contains from 0.01 to 25 percent by weight of at least one alkaline earth peroxide, based on the ready-to-use dye mixture, and from 0.01 to 25 percent by weight of at least one inorganic or organic acid, salt of the at least one organic or inorganic acid or mixture of the salt and/or the at least one acid, based on the ready-to-use dye mixture.
Claims13
