Flavor oils are an aromatic addition to oil soluble products such as lip balms, lipsticks, body butter, & edible massage oils. Recommended usage rate is 1-5%. Your recipe can be multiplied by .01 -.03 to determine the amount of the flavor oil you should add. For instance, if you had 16 oz of lip balm base & wanted to use 2% flavor oil, you would multiply 16 x .02 = .32. You would add .32 oz of flavor oil to your base. Test with the smallest amount of flavor oil and then increase if desired.
