Abstract

Agent for oxidative coloring of keratinic fibers comprising a specific combination of non-ionic emulsifiers with a differing degree of ethoxylation and a specific combination of interfacially active substances comprising at least one anionic, at least one zwitterionic and at least one amphoteric surfactant. The agents provide good coloring characteristics while simultaneously protecting against damage to human hair. In particular the agents allow for colors with high color intensity and an improved gray coverage. The agents also provide significant advantages with regard to viscosity stability during storage and use and an improvement in shear sensitivity.
