Table 3.

Table of $\alpha$ and R² values for log fitting of IL/DMSO solutions with Equation (1). Values for 25 °C pure solvent fitting are taken from the literature [48]. Errors in $\alpha$ values are estimated from the least-squares fitting using the ‘jack-knife’ or numerical substitution method [65].

Biopolymer Solute	Temperature/°C	$\mathit{\alpha }$	R2

10 wt% SF	100	0.44 ± 0.01	0.95
None	100	0.49 ± 0.01	0.91
None	25	0.15	0.99
