DSC crystallisation curves of SLN and NLC aqueous dispersions consisting of Miglyol® 812 as the liquid lipid in combination with different solid lipids or blends of them. Graphs (A), (B) and (D) show the melting behaviour of formulations prepared with Compritol® 888 ATO without curcumin, with 0.0125% w/w curcumin and with varying type or concentration of surfactants, respectively. Graph (C) displays the crystallisation curves of formulations fabricated with either Precirol® ATO 5 or blend of the two solid lipids at 50:50 w/w ratio. The exact composition of the formulations can be found in Table 2. The normalised curves were shifted along the ordinate and presented in sets for better visualisation.
