Oil soluble color solubility hair oil

I am using below mentioned colours in our All variants of Hair Oils.

 CI 47000 (Yellow), CI 61565 (Green) & CI 26100 (Red)

I have notice that in our Manufacturing area, to Make one hair oil variant it will take more than 5 to 6hr, the reason is we need to mix the base (Light liquid Paraffin) with color for 5hr, then only colours are properly solubilizing in Mineral Oil (Light Liquid Paraffin).

 I need to reduce our manufacturing time from 6hrs to 2hrs, 

If anybody can help, it would be great

    C12-15 Alkyl Benzoate will work there. 
  • I think color solubility matters. Try different Oil soluble color.

    @chemicalmatt already did. He proposed using a "pigment dispersion aid" (dunno if there is a proper name for this). There's a bunch of such compounds available which also tend to be well suited for sunscreen dissolution, you just have to search for them if you don't like Cetiol AB.

    try heating it up and/or applying shear to it; from experience, I know CI 47000 in particular is very, very slow to dissolve at room temperature
