Description
The interfacial stabilizer layer in lipid emulsions and suspensions controls the lipid oxidation of
encapsulated bioactive compounds and the crystallization of the nanoemulsions. As a model system
tetracosane (C24 alkane, TCS) nanodispersions stabilized by the lecithin 1,2-dimyristoyl-sn-glycero-
3-phosphocholine (DMPC) was considered here. The emulsion droplets (about 65 nm in diameter,
as measured by photon correlation spectroscopy) exhibit a strong super-cooling (ΔT about 20 K)
and crystallize in an for TCS unusual orthorhombic crystal structure (space group Pca21 as verified
by wide-angle x-ray scattering).
