  • pigment cplor is fading

    Posted by cherri on April 17, 2014 at 11:10 am


    I am making a product very light watery serum type for face and the ph around 5-6 and using a blue pigment which contains below ingredient:

    Mica, Titanium dioxide, Tin oxide, and Ferric ferrocyanide

    It seems like the color is fading at elevated temperature. Any suggestion?

    Thank you for your help!

    well pretty clear that your blue ferrocyanide aint stable at higher temperatures, either use a different grade or a color stabilizing agent.

    That might be one of the factors too, check the TDS to check the optimum pH for ferrocyanide.
