Yellow Oxide: A lovely muted earthy yellow, this is a great alternative to FD&C Yellow. Use this anytime you want a more natural look to your soaps. Approved for use in cosmetics, including lip products.
NOTE: To achieve a soft to medium yellow in cold
process soap, use 1/4 teaspoon for every 16 oz. of oil. To achieve a medium to
dark color in cold process, use 1/2 tsp. for every 16 oz. of oil. Keep in mind
that base colors (especially some olive or pomace oils) will affect your final
outcome.
