Titanium dioxide is useful for whitening soaps. The rate of usage is between 1 teaspoon and 1 tablespoon per pound of oils, variable based on the whiteness you desire. The higher end of usage may result in a chalky soap, and it is recommended to use at a lower rate and increase as needed. This item is dispersible in water and available in 2 oz and 1 pound amounts. It is packaged in a 5 mil plastic stand up pouch with a resealable zip top.
