Brilliant Blue mica is a bold blue that holds true in cold process soap. A lot like our Vibrance blue, but with a little extra pop. Great in melt and pour soap too!
Recommended use rate in cold and hot process soap is 1 tsp. per pound of oils. For melt and pour, the recommended use rate is .5 tsp. per pound of base.
We cannot recommend our green and blue micas for bath bombs, since the color additives contained in them (chromium oxide green and ultramarine blue) are not approved by the FDA for use on lips or other mucous membranes. Although bath products have historically been considered externally applied cosmetics, bath bombs are different because the product is put in the bath and there is prolonged exposure to mucous membranes. We have personally clarified this information with the Director of the Color Certification Branch of the FDA. Have questions? Contact Us.
