^aThe results are an average of at least three measurements. K4M_S, K15M_S, and K100M_S represent three batches of HPMC with different viscosity grades from Anhui Shanhe Pharmaceutical Excipient Co., Ltd. (China). K4M_T, K4M-CR_T, K15M_T, K15M-CR_T, and K100M-CR_T represent five batches of HPMC with different viscosity grades from Dow Chemical (USA). The viscosity of K4M, K15M, and K100M is 4000, 15,000, and 100,000 mPa·s, respectively.
