OXIDIZING COLORANT

A composition for oxidatively treating hair includes-50-96 wt. % water; 0.5-20 wt. % hydrogen peroxide; at least one linear saturated 1-alkanol with 12-30 carbon atoms in a total volume of 2.7-6 wt. %; at least one polyethylene glycol ether of a linear saturated C12-C22 alkanol with 15-30 ethylene oxide units in the molecule, in a total volume of 0.3-1 wt. %; at least one anionic surfactant in a total volume of 0.3-1 wt. %; at least one cellulose ether in a total volume of 0.1-0.5 wt. %; and at least one oil in a total volume of 0.1-0.5 wt. %. The composition is highly suitable as an oxidant for powdered color preparations, containing oxidizing coloring intermediates and also pigments, which do not permanently change the color of the fibers, as well as, optionally, including solid inorganic alkalizing agents, as well as, optionally, ammonium salts, like ammonium chloride and ammonium sulfate, in particular with respect to the application properties of the application mixture.
