We note that our emulsions were independently prepared, leading to potential variations in droplet size distributions. Hence, we simulated hydroperoxide and aldehyde kinetic curves for an emulsion with surfacevolume mean diameter (D32) of 1.2, 1.4, and 1.6 µm (Figure ). The simulations show a clear difference in the kinetic curves for variations in D32, which indicates that the variation in kinetic curves in
