Colour pigments should develop their full effect in lipstick, make-up or eye shadow. For this, homogenising plants must carry out several steps efficiently and without interruption. We plan and supply plants that help you incorporate pigments evenly and with strong colour into your cosmetic products.

Heated agitatorsSolids do not settle, so consumption falls.
Low-dust inductionThe plant draws in powders cleanly and incorporates them.
Protective atmospherePressure and vacuum-proof design for sensitive processes.

Process steps in one plant

Pigments go into bases with very different properties. Therefore, modern process plants handle all key steps at the right temperature:

  1. 1MeltingFirst, the plant gently melts fats and waxes.
  2. 2InductionNext, it draws in powders below the liquid level with little dust.
  3. 3DispersingThen the tool breaks up agglomerates (pigment grinding), see dispersion.
  4. 4HomogenisingFinally, the homogeniser makes the base even and stable, see homogenisation.

What matters in the plant

  • Heated lines in the agitators stop solid particles from settling
  • Low-dust powder induction keeps processes clean
  • Pressure and vacuum-proof machines allow production under a protective atmosphere
  • In addition, we design agitators and homogenisers in advance to suit your product
  • CIP cleaning built into the lid shortens production times and meets GMP

Would you like to incorporate colour pigments more efficiently and with stronger colour? We are happy to review your process and suggest a suitable new or used plant.

FAQ: Incorporating colour pigments in cosmetics

Why do colour pigments need to be dispersed?

Pigments come as agglomerates. Only dispersing breaks them up and distributes them evenly, which determines colour strength, opacity, shade and stability of lipstick, make-up or eye shadow.

Which processes are used?

Melting of the fat and wax base, low-dust vacuum induction of pigments, dispersing with a rotor-stator homogeniser and, if required, fine grinding on roller or bead mills.

How is pigment settling prevented?

With heated pipes and agitators, constant mixing and fine particle size.

Which machine is suitable?

Heatable, pressure and vacuum rated homogenising mixers with scraper agitator and powder induction, also under protective atmosphere.

Does SEEFRIED support pigment processing?

Yes, with process consulting, plant design and suitable used homogenising mixers.
