Soluplus
Figure 6: Effect of Soluplus on the DSC curves and FTIR spectra of IMC-NIC (molar ratio = 1:1) physical mixture after solvent evaporation. Key: a) IMC-NIC co-crystal in the absence of Soluplus;
b) Prepared by 0.1:1 (w/w) weight ratio of Soluplus: IMC-NIC mixture; c) 0.2:1 (w/w) weight ratio of Soluplus: IMC-NIC mixture; d) 0.4:1 (w/w) weight ratio of Soluplus: IMC-NIC mixture; e) 0.8:1 (w/w) weight ratio of Soluplus: IMC-NIC mixture.
