Can I use fragrance oils in lip balm?
Edited
No. Fragrance oils are formulated for scent-only cosmetic applications and are not safe for use in lip products. They can irritate the lips and will generally taste unpleasant. For lip balms, lip glosses, or any product that will contact the mouth, you should use a flavor oil specifically designed for that purpose. Nature's Flavors carries a range of flavor oils that are appropriate for lip-safe and edible applications.
