Compositions for dyeing keratin fibers

A dyeing composition for dyeing keratin fibers obtained by the process comprising the steps of:

• i) adding at least one anionic surfactant, at least one alkoxylated C6-C24 fatty alcohol, at least one C6-C24 fatty alcohol and at least one oxidation dye to a water phase at a temperature from about 50° C. to about 90° C. and under agitation to form an emulsion;
• ii) cooling the emulsion obtained in step (i) to a temperature from about 30° C. to about 50° C. and under agitation;
• and
• iii) adding at least one cationic surfactant and ammonia to the emulsion obtained in step (ii) under agitation, the at least one cationic surfactant comprising cetrimonium chloride,
• wherein the dyeing composition includes about 0.1-10 wt. % of ammonia,
• wherein the ammonia is the only alkalizing agent present in the composition such that the composition is free from carbonates, alkanolamines and C1-C4 alkyl alkanolamines, fatty acid salts thereof, or mixtures thereof, and
• wherein the composition exhibits optical anisotropy.
