  • Colorant for conditioner

    Hi. May I ask what colorants do you use for rinse off conditioner? I tried water based colorant solution, yet it did not mix homogenously. Here is my formula.

    water - qs
    cetrimonium chloride - 2.5%
    cetearyl alcohol - 6.5%
    hydrogenated polydecene - 1%
    preservative - 1%
    polyquaternium 7 - 2%

    Thank you!

    Need to add more emulsifier like ceteareth-20 or 25, since 6.5% cetearyl alcohol seem to high, and make HLb system to low,

    @zacchaeus Were you using colorants or pigments? I’ve used colorants in conditioners, and they mixed very well (since they are water soluble), even when added directly. The main issue there would be the long term stability, since uually water soluble colorants are anionic in nature, and they might fade quite quickly in the presence of cationic bases.
