摘要: The main component of candelilla wax (CW) is hentriacontane, an n-alkane (C31H64) with self-assembly capability when dissolved in organic solvents. We have shown that CW develops organogels using safflower oil as the liquid phase. This research also has showed structural organization CW-organogels depends on cooling rate, supercooling (i.e., thermodynamic strength for crystallization), and annealing process. Additionally, thermomechanical microstructural characteristics were compared ones by dotriacontane (C32H66; C32). Such comparisons done a rheometer True-gap? system factorial experiments design where variables evaluated were: gelator concentration (1% 3%), gelation temperature (Tset, 5oC 25oC), rate (1oC/min 10oC/min). results provided better correlation thermal behavior, solid phase content (SPC) microstructure. DSC independently Tset, concentration, C32 had properties than CW. microphotograph developed larger needle-like crystals higher extent branching while crystallized platelets. presence minor molecular components triterpenoids, nonacosane, tritriacontane) profound effect crystal size hentriacontane from CW-organogeles. at significantly lower SPC Nevertheless, achieved G? profiles CW, particularly 1oC/min 3% concentration.
