Percentage of number of hydrogen bonds in synergistic or antagonistic antioxidants, compared to the number of hydrogen bonds in additive mixtures. HBx denotes the weighted number of hydrogen bonds available between the compounds for either antagonistic (HBa) or synergistic mixtures (HBs). Similarly, HBadd represents the weighted number of hydrogen bonds available between the compounds for additive mixtures. As a result, the y-axis represents the relative percentage of available hydrogen bonds compared to additive antioxidant mixtures (baseline).
