The effects of n-Decane (DCA) and n-Octane (OCT) on the crystallization of n-Hexadecane (HD) were investigated to systematically assess the effect of lipid component interactions on lipid supercooling. We plotted the crystal nucleation temperature against the equilibrium freezing point for the HD-DCA and HD-OCT systems and found a first-order correlation. However, slope evaluation revealed that HD did not supercool as much as the aqueous solution system. n-Alkanes are nonpolar and form weaker
