Colorant for conditioner

zacchaeuszacchaeus Member
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!
