  • Patent number: 8545575
    Abstract: A method for manufacturing a coloring agent for keratin fibers is provided. The method includes directing a composition A from a container A by a filler apparatus through an inlet opening into a second container B containing a second composition B. The composition A is flowable. The coloring agent for keratin fibers exits from the container B as a mixture of the composition A and the composition B. The composition B comprises an oil component having a melting point below about 25° C. and the composition A and/or the composition B comprises an emulsifier.
