PROCESS FOR PRODUCING A COLORANT FOR KERATIN FIBRES

摘要

Process for producing an active ingredient preparation comprising a first flowable composition A and a second composition B, in which - the first composition A is passed from a container A - by means of a filling device - via an inlet opening - to a second container B containing the second composition B, and the colorant for keratin fibres emerges as a mixture of compositions A and B from the container B, characterized in that a) the composition A comprises at least one polymeric thickener and b) the composition B comprises at least one fatty alcohol, is suitable for producing homogeneous colorants for keratin fibres with a viscosity suitable for treating hair.
