showing somewhat broader distributions. The higher PDI values are primarily due to a minor population at larger sizes, in particular for A-p R EtEtOx-A. Obviously, the formulations of the chiral compound S-IBU are quite similar but appear less uniform compared to the curcumin formulations, however, no clear trend between the different chiralities can be seen at day 0. After 7 days' storage, the formulations remain Long-term stability studies of the formulations.
