Wetting front velocities derived for the experimental sets shown in Fig. 6.

	Vf (µm/s)	${\overline{\mathbf{[}\mathit{I}\mathit{P}\mathit{A}\mathbf{]}}}_{\mathit{l}\mathit{i}\mathit{n}\mathit{e}\mathit{a}\mathit{r}}$ (mol%)	${\overline{\mathit{\gamma }}}_{\mathit{linear}}$ (mN/m)
Set 1	45.9	3.19	37.1
Set 2	25.9	3.11	37.5
Set 3	17.9	3.08	37.6
Set 4	11.2	2.97	38.1

The front velocities are extracted from the experimental wetting curves by linear regression assuming A_wet = (v_f t)². The IPA concentration and surface tension was taken as the average value over the linear part of the curve (Supporting Information).
