Yellow Vibrance mica is our most dependable yellow. It is bright, sunny, and completely reliable in cold process. Some have reported this mica turning orange during saponification, so if this happens don't be alarmed! Within 24 hours this mica will turn back to the bright sunny yellow color you were expecting.
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 carrier oils, now use 3 tsp of oils and 1.5 tsp. of poly 80. If your bath bombs are too wet, decrease the amount of poly and carriers oil by the same ratio. The addition of polysorbate will prevent staining or a mica powder ring around the tub.
