Vegetable Oil-based Ricinelaidic Acid Organogels—Phase Behavior, Microstructure, and Rheology

摘要: Publisher Summary Hydroxy Octadecanoic Acid (HSA) is a well known organogelator molecule. Studies with its isomers have led to greater understanding of the relationships between molecular structure and organogel formation structure. 12-HAS, in particular, commonly used cosmetics as lubricating greases coatings. In organic solvents, 12-HSA forms long, rigid fibers through hydrogen bonding, these then are linked together crystalline monoclinic domains. HSA research has served model for further exploration organogels. Amanda J. Wright Alejandro G. Marangoni, identify new molecules, turned 12-hydroxy, 9-trans-octadecenoic acid. Ricinelaidic (REA) derivative 12-HAS similar Given trans configuration double bond on carbon 9, it was hypothesized that molecule would physically align manner saturated molecule, 12-HSA. This chapter summarizes Marangoni's REA gelation vegetable oils, including influence temperature concentration gel formation, microstructure, stability. The hydroxylated fatty acid ricinelaidic (12-hydroxy-9-trans-octadecenoic acid, REA) an capable gelling triacylglycerol-based depending temperature, oil purity.
