Ultraviolet Blue - This powdered oil based color is approved for soaps and lotions. Unlike some neon colors on the marketplace, it is FDA approved for soaps and lotions products. As a fun little twist, it does glow under a black neon light. For external use only (which means, no lip products). This colorant is not approved for eye make up.
Instructions for Use: To use in melt and pour, disperse and mix well in liquid glycerin (similar to working with a pigment). We found that our Mini Mixer makes quick work of the dispersing! While this is a non-bleeding colorant, if you add too much to your soap it can migrate into other colors in the soap design or stain washcloths. We recommend starting out at 1/16th to 1/8th teaspoon per pound for melt & pour soaps. For cold process, add 1 teaspoon of oxide to 1 tablespoon of a carrier oil like Sweet Almond or Olive Oil and mix well using a mini mixer. For more information on oxides in soap, check out this blog post.
To create the color in the sample of cold process soap above, we used 1 teaspoons of colorant in 1 pound of soap.
