Sunscreen oils are neither effective or approved. I have seen some of the fuzzy math used to support the “theoretical” SPF values. The logic is (and please I am spit balling these numbers) “Oil X has an SPF of 3.5, Oil Y has an SPF of 8 and Oil Z has an SPF of 6 so therefore my SPF is 17.5.” Well this is patently flawed as these are projected SPF for the oil at 100% concentration. At best you could project an SPF based upon the percentage used and SPF, similar to the method by which an overall HLB value is obtained from 2 or more emulsifiers.
That said, the above exercise is useless since SPF must be measured by a testing lab not extrapolated.
I guess the answer is you can flavor (did you mean fragrance since this is a topical, not oral dosage form) with anything since it is not a sunscreen either by performance or the legal definition. The oils are not approved under the FDA Sunscreen monograph.
Selling this product with SPF or even as a sunscreen would expose you to liability and scrutiny of the FDA.
