Synchrotron SAXS data from solutions of Polydisperse core-shell ellipsoidal micelles of POE sorbitan higher order esters fraction (F4) with no or low amount of the fatty acid myristic acid (MA) (< 100 µg/ml) in aqueous solution of 4% methanol, pH 7 were collected on the EMBL P12 beam line at the PETRA III storage ring (DESY; Hamburg, Germany) using a Pilatus 6M detector at a sample-detector distance of 4 m and at a wavelength of λ = 0.124 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 5.00 mg/ml was measured at 20°C. 40 successive 0.100 second frames were collected. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.
