COMPOSITION FOR OXIDATION DYEING OF HUMAN KERATIN FIBRES, AT A PH GREATER THAN OR EQUAL TO 8, COMPRISING A FATTY ALCOHOL, A FATTY ESTER AND A CATIONIC SURFACTANT, METHOD USING SAME AND DEVICE

摘要

The present invention relates to a dye composition for the oxidation dyeing of human keratin fibers, at a pH greater than or equal to 8, comprising at least one oxidation dye precursor, at least one fatty alcohol, at least one fatty ester and at least one cationic surfactant, where the weight ratio of the at least one fatty alcohol and the at least one fatty acid ester being greater than 2 and less than 10. In addition, the present invention relates to a ready-to-use composition obtained by extemporaneously mixing the dye composition with an oxidizing composition, before use, and a method for dyeing keratin fibers in which the ready-to-use composition is applied to hair fibers.
