Pink Blue UltraMarine Is a great shade of pastel pink. 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 such as olive oil or sweet almond. Suggested uses- 2 teaspoons of colorant (about 0.15 oz before dispersing) in 1 pound of soap.
