Most Effective Antioxidants for Long-term Oxidation Mitigation of O/W Emulsions?

What are the most effective low odor antioxidants (bio-based derived from plant origin feedstocks) available to minimize the oxidation of O/W emulsion skin products over the long-term (for 18 - 24 months)?

Grape seed extract and vitamin E (tocopherol) have long served as tried and true antioxidants while bringing other skin benefits to skin products.  I know I can look up Oxygen Radical Absorbance Capacity (ORAC) values.  But I would like to know what works in the real world of cosmetic products.

What are other low odor/low scent antioxidants (preferably with additional benefits beyond protection from oxidation) that give skin products similar or even greater antioxidant protection than grape seed extract and vitamin E?

Thanks!
