White spots on hot pour cream

Hi, I encountered some problem during formulating a hot pour cream. There are some white spots on the surface of finished product. 

And this is what I encountered during milling using three-roll mill. 

I'm using castor oil and Pentaerythrityl Tetraisostearate which I believe are good pigment dispersants to disperse the pigment before milling but it came out like this.

May I know what's wrong in my formulation or is there any techniques to disperse it properly?

Thank you in advance for the help.

Thank you very much.

  • What happened when you squeezed them?

  • I've revised my formula and using uncoated pigment and filler and it is better. Just that yellow spots is observed instead of white spots. The texture is fine with no abnormalities. Any idea?
