The data set contains ASCII files (comma delimited) for the following:
- Small-angle neutron scattering (SANS) curves and fits for cocamidopropyl betaine (CAPB), cocamidopropylamine oxide (CAPOx) and sodium lauroyl sarcosinate (SLS) as a function of the surfactant concentration in sodium chloride (NaCl) 1wt% in 100% heavy water (deuterium oxide, D2O).
- SANS curves and fits for CAPB/sodium dodecyl sulphate (SDS), CAPOx/SDS and CAPB/SLS as a function of the surfactant concentration in NaCl 1wt% in 100% D2O.
- Oscillatory shear frequency sweeps for CAPB/SDS and CAPOx/SDS solution at 60/60 mM of surfactant in aqueous NaCl 1wt%.
- SANS curves and fits for CAPB, CAPOx and SLS mixtures as a function of the surfactant concentration in oxidized cellulose nanofibrils (OCNF) 1wt% in aqueous NaCl 1wt% in 100% D2O.

Data collection method:
Rheological measurements were conducted on a stress-controlled Discovery Hybrid Rheometer, Model HR-3 (TA Instruments, USA) equipped with a sand-blasted 40 mm parallel plate geometry over a sand-blasted lower plate. Temperature was controlled via a Peltier unit (±0.1 °C) and kept at 25 °C. A thin layer of low viscosity mineral-oil was added to the edge of the geometry to prevent sample evaporation. Oscillatory amplitude sweeps were done at a fixed angular frequency (ω) of 6.28 rad·s-1 and amplitude strain (γ) from 0.01 to 100%. Frequency sweeps were conducted at γ of 0.1%, within the linear viscoelastic range, covering ω of 0.01 to 50 rad·s-1. All samples were measured between 24 and 48 hrs after preparation. Small-angle neutron scattering (SANS) measurements were conducted on the time-of-flight diffractometer instrument SANS2d at the STFC ISIS Neutron and Muon Source (Didcot, UK). Incidental wavelengths from 1.75 to 16.5 Å were used with a sample-to-detector distance of 4 m, corresponding to a total scattering vector range q from 4.5 × 10-3 to 0.75 Å-1. The sample temperature was controlled by an external circulating thermal bath (Julabo, DE). The scattering intensity was converted to the differential scattering cross-section in absolute units using ISIS standard procedures. Samples were loaded in 1 mm path length, 1 cm wide optical quartz cells. Constrast match experiments were done at 15 wt% D2O, which is the contrast match point for the surfactant mixtures. All other SANS experiments were done in 100 wt% D2O.
