Table 2.
Table showing the dissolution behaviour of SF over time (up to 48 h) at different EmimAc:DMSO solvent ratios. All images are taken at ×20 magnification using transmission cross-polarised light microscopy. Scale bars shown are equivalent to 1 mm. Note the presence of undissolved solid after 48 h at 2:8 EmimAc:DMSO solvent composition. Table heading E:D refers to the solvent ratio between EmimAc and DMSO.
