Antioxidant calculation


I was wondering if there is a specific calculation to determine how much antioxidant my formulation needs (based on the oils that are being used in the formulation), or if I can simply add the concentration suggested by the ingredient manufacturer (and then I conduct a stability testing to analyze the product oxidantion). How do you guys determine the antioxidant concentration of your formulas?

Thanks in advance!

    Depends on your chosen medium @tecnico3vinia. Using BHT, I use a very rough measure of 0.10% for every 20% total linoleic/linolenic unsaturated triglyceride content, and that is likely more than enough.  Using mixed tocopherols - NOT vitamin E acetate -  a bit more, say 0.15%. Most of the time 0.01 - 0.05% is fine.  For high oleics, virtually none.
