In contrast, at 6 g/L, 8 g/L and 10 g/L CUR feed, there was a significant amount of precipitate with a transparent supernatant observed, with the notable exception the formulation with A-p RS PrMeOx-A at 10 g/L CUR feed. The appearance of A-p RS PrMeOx-A/CUR=10/10 (g/L) (feeding ratio) was similar to the A-pEtEtOx-A formulations at 10 g/L CUR feed, and different to A-p R PrMeOx-A, A-p S PrMeOx-A and M A-pPrMeOx-A formulations at 10 g/L CUR feed.
