How much fragrance oil should I add to M & P soap base?
Our recommendations are based solely on the use of our soap bases and fragrance oils. Recommended industry standard is a 2% fragrance load. As a general rule, you can add 2 teaspoons of fragrance oil per pound (16 ounces) of soap base. We use 2 teaspoons per pound in our soaps and the scent has good “staying power” when soaps are wrapped. Excessive fragrance oil can cause pitting on the inside of molds and may be irritating to the skin. Remember, more is not always better.
