Abstract:
The production of lipsticks was until a few
years ago one of the more complicated techniques
in the cosmetic industry. Manufacturing
methods have been improved considerably. The
development of the casting system and the introduction
of the corundum stone mill for the preparation
of colour pigments have contributed to
simplifying and economizing the production
process. Moreover the traditional method of
premixing pigments with a kneadermixer and
then grinding them on a triple roller mill did not
sufficiently guarantee the dispersion of the colour
in the past.
