Agents for oxidizing tinting of hair based on a gel-like support material and a mixture of dyes dissolved therein, whereby the support material contains A) from 8 to 16 % by weight of oleic acid, B) to 8 to 30 % by weight of nonyl phenol ethoxylated with 2 to 6 moles of ethylene oxide and/or fatty alcohol having from 12 to 20 carbon atoms and ethoxylated with 2 to 6 moles of ethylene oxide, C) 6 to 14 % by weight of fatty alcohol with 10 to 20 carbon atoms, D) from 4 to 18 % by weight of ethanol and/or isopropanol and E) from 16 to 70 % by weight of water. These new compounds allow the ammonia contained therein to be released slowly and, with the addition of hydrogen peroxide, result in a less dark coloring than in the case of known gel-like hair tinting agents. |
