SAXS data is given in text files (.txt) in 6 columns which are Q, intensity, uncertainty in intensity, uncertainty in Q (set to 0 here), and two columns for slit smearing parameters which were not used in this work (thus the 5th column replicates values in column 1 and the last column is set to 1) The dataset contains SAXS and SANS data for the systems described in "Mix-and-match diols: Adjusting self-assembly of micellar phases in choline chloride eutectics" which has been corrected for instrumental parameters using standard procedures and had appropriate backgrounds subtracted. The datasets are shown as graphs in the paper, and were used in the fitting procedures described. 2022-11-10 University of Bath public https://data.isis.stfc.ac.uk/doi/INVESTIGATION/85253401/ raw SANS data from experiment RB1620126 RightsHolder University of Bath Engineering and Physical Sciences Research Council https://doi.org/10.13039/501100000266 EP/L016354/1 EPSRC Centre for Doctoral Training in Sustainable Chemical Technologies cent_sus_tech Small-angle neutron scattering (SANS) measurements were performed at STFC ISIS Neutron & Muon Source, under beamtime allocation RB1620126, on the time-of-flight diffractometer Larmor operating in conventional SANS mode, at 50°C in 1mm thick quartz Hellma cells. Data were collected over a range of 0.004 Å-1 ≤ Q ≤ 0.9 Å-1, using neutrons of wavelength 1.5 nm ≤ lambda ≤ 17 nm and a detector distance of 4 m. Samples for SANS were prepared on-site, in a concentration series above the measured CMC of C12TAB in ethaline, 2, 5, 10, and 20 wt.% of C12TAB, in two contrast sets, fully-protiated C12TAB in [d9-ChCl][d6-EG]2, and d34-C12TAB in fully-protiated ChCl:EG. Data were reduced using the standard protocols of the beamline to procure the scattered intensity in absolute scale, I(Q), vs. the momentum transfer vector, Q. Synchrotron small-angle X-ray scattering measurements were made on the instrument I22 at Diamond Light Source under beamtime allocation SM15194. Samples were placed into soda-glass capillaries with 10 µm wall thickness and path length of 1.5 mm. Operating at a power of 18 keV, SAXS measurements were taken using a Dectris Pilatus-2M detector over a Q-range of 0.007 Å-1 ≤ Q ≤ 0.6 Å-1. Samples were held at a temperature of 50°C to prevent crystallisation, using a water-recirculating brass block sample holder. Data were reduced using DAWN software and the standard protocols of the beamline to procure the scattered intensity in arbitrary scale, I(Q), vs. the momentum transfer vector, Q. Backgrounds, of which the most pertinent source was the Kapton beam window, were subtracted from the measured scattering to obtain reduced data SANS data were reduced from the raw data using Mantid software using the standard beamline procedures on the Larmor instrument. SAXS data were reduced using DAWN software (Basham, M.; Filik, J.; Wharmby, M.T.; Chang, P.C.Y.; El Kassaby, B.; Gerring, M.; Aishima, J.; Levik, K.; Pulford, B.C.A.; Sikharulidze, I.; et al.
