What are the strongest antioxidant ingredients available in the chemical/personal care industry that formulators can use to add to lotions and creams at low usage levels in order to maximize the final product's oxidative stability?
In the interest of maximizing a lotion or cream product's shelf life and minimizing its chance of going rancid; what ingredients show particularly powerful antioxidant activity at relatively low percentage usage levels?
Also, is there an index/list available comparing the Oxygen Radical Absorbance Capacity (ORAC) of various ingredients available to formulators?
Any suggestions, comments or discussion about antioxidant ingredients would be greatly appreciated. Thanks!
