Bronze Brown is a beautiful mica that is wonderful for coloring cold process, hot process, and melt and pour soaps. It is a very stable dark rich brown like chocolate.
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. To use in bath bombs polysorbate 80 must be used. Use polysorbate at half your oils. For example, if you use three teaspoons of oils, now use 1.5 tsp polysorbate 80 and 1.5 tsp. oils. The addition of polysorbate will prevent staining or a mica powder ring around the tub.
