Natural indigo powder creates a denim blue color in cold process soaps. Our current batch of indigo powder has a super high natural dye concentration of 6.2%. Lower concentrations can turn gray in soaps. Our indigo is a true dark denim blue with a use rate of 1 tsp. per pound of oils.
For best results, add about 1 tsp. of indigo per pound of oils.
Mix in oils and then add to soaps to prevent speckling and ensure maximum color dispersion.
Due to indigo being an unapproved cosmetic colorant per the FDA, it is for soap only.
