  • Product pH: This colour will not change in high pH products.
  • Colour Fading: This colour is not light sensitive.
  • Colour Bleed/ Migration: If your product design has layered colours, this colour will not ‘bleed’ or migrate between the layers.

Usage Directions

For Mineral Makeup: Add the powdered colour directly to the base.

For Cold Process Soaps: Mix 1 teaspoon colour with 1 tablespoon of any lightweight oil or glycerin. Then slowly add the dispersed colour to your soap batter, one teaspoon at a time.

If you want to eye-ball it: Add the colour pigment to a small amount of liquid glycerin. Mix well. Then combine the mix to your soap base.


  • If you want a darker colour, add more of the powder oxide pigment. Ensure to add small at a time to see what it looks like, and avoid adding too much.
  • If you use just-enough amount of colour in your soap, you should not have coloured foam/ bubble/ lather. Therefore, a sign that you have used too much colour is if your soap bubbles are not white.
