  Anhydrous pigment suspension

  Posted by nfar on October 7, 2021 at 4:45 am

  Hi!
  How can I suspend pigments in oil without the final product feeling heavy or greasy? I’ve tried polyamide-3 however it’s such a tricky ingredient to melt. I would love to keep the formula anhydrous. Any help or suggestions would be SO appreciated!

  Add hydrophobic silica powder like aerosil 987

  in my experience a combination of hydrogenated castor oil and hydrophilic fumed silica (e.g. Aerosil 200 / CabOSil M5) works well
