How much flavor oil should I put in lip product formulations?
Edited
Because lips are sensitive, light dosing is recommended. Add more as needed until you achieve the desired result. Requesting a COA and INCI documentation can help with compliance and transparency.
For lip applications, keep the following in mind when applying flavor oils in your lip products:
Use edible flavor oils only
Avoid fragrance oils entirely
Start with minimal amounts
Increase slowly while testing
