Antioxidants for oils
I want to add rosemary oleoresin leaf extract (ROE) to my facial oil formula. I already have 0.1% tocopherols in there, and want to add ROE for the synergistic antioxidant effects it has with tocopherols. Do I simply add ROE? Or do I reduce the amount of tocopherols when adding ROE for a total of 0.1% antioxidants? And how much ROE should be added?
Facial oil consists of q.s. squalane, 15% black seed oil, and 0.1% mixed tocopherols T50.

.1% of MTE is plenty, as would adding the same amount of ROE.
As both beg to be oxidized…store them in the refrigerator…and throw them out after 6 months, unless you are nitrogen blanketing them between uses. Minimize number of times you open the lid.
Generally, I recommend people use .1%….simply for the fact that they struggle to measure quantities less than that….as you can see use rate typical of industry in attached.
If you are buying oils off the street….chances are incredibly high…that they have already been adulterated with MTE. If you are buying oils that originated from ICSC out of Denmark, they were treated with ROE as they were processed.
Good Luck.
