Definitions

• the invention relates to a liquid preparation for oxidation hair dye.
• Such preparations consist of hair dye precursors and a carrier suitable for use on the hair.
• Preferred carriers are cream-type emulsions of the water-in-oil type and aqueous or aqueous-alcoholic solutions of soaps.
• Such oxidation hair dye bases based on liquid, aqueous or aqueous-alcoholic soap solutions form a viscous to gel-like, ready-to-use hair dye preparation after addition of the aqueous solution of the oxidizing agent required for the development of the oxidation colors.
• Oxidation hair dye preparations based on liquid, aqueous or aqueous-alcoholic soap solutions represent an advantageous form of confectioning because, after adding the aqueous solution of the oxidizing agent, they form a viscous to gel-like dye preparation which adheres to the hair when used.
• the task was therefore to find stabilizing substances, the use of which, even in lower concentrations, leads to a high increase in the viscosity of the formulation.
