OIL GELLING AGENT AND OIL GEL COMPOSITION CONTAINING THE SAME
-
Paragraph 0017; 0023, (2017/05/16)
PROBLEM TO BE SOLVED: To provide an oil gelling agent which can form a highly stable gel by blending in an oil solution in a small amount and does not need to expose to excessive high temperature in a step of producing an oil gel, and to further provide an oil gel composition containing the oil gelling agent and the oil solution. SOLUTION: There are provided: an oil gelling agent consisting of an alkanol amide derivative represented by the general formula (1); and an oil gel composition containing the oil gelling agent and the oil solution. [R1CO is an acyl group having 16 to 22 carbon atoms containing a hydroxyl group; R2CO is a different composition from R1CO and is a linear/branched alkylene group having 14 to 22 carbon atoms which may contain an unsaturated bond or a polyalkylene group; X is H or an alkyl group having 1 to 3 carbon atoms, a hydroxyethyl group or a hydroxypropyl group; n is an integer of 1 to 3.] SELECTED DRAWING: None COPYRIGHT: (C)2016,JPOandINPIT
Synthesis, calorimetric studies, and crystal structures of N, O-diacylethanolamines with matched chains

Recent studies show that N-, O -diacylethanolamines (DAEs) can be derived by the O -acylation of N-acylethanolamines (NAEs) under physiological conditions. Because the content of NAEs in a variety of organisms increases in response to stress, it is likely that DAEs may also be present in biomembranes. In view of this, a homologous series of DAEs with matched acyl chains (n = 10-20) have been synthesized and characterized. Transition enthalpies and entropies obtained from differential scanning calorimetry show that dry DAEs with even and odd acyl chains independently exhibit linear dependence on the chainlength. Linear least-squares analyses yielded incremental values contributed by each methylene group to the transition enthalpy and entropy and the corresponding end contributions. N-, O-Didecanoylethanolamine (DDEA), N-, O-dilauroylethanolamine (DLEA), and N-, O-dimyristoylethanolamine (DMEA) crystallized in the orthorhombic space group Pbc21 with four symmetry-related molecules in the unit cell. Single-crystal X-ray diffraction studies show that DDEA, DLEA, and DMEA are isostructural and adopt an L-shaped structure with the N-acyl chain and the central ethanolamine moiety being essentially identical to the structure of N-acylethanolamines, whereas the O-acyl chain is linear with all-trans conformation. In all three DAEs, the lipid molecules are organized in a bilayer fashion wherein the N-acyl and O-acyl chains from adjacent layers oppose each other. Copyright
Synthesis, Characterisation and Surfactant Behaviours of Acylaminoethyl Esters of Fatty Acids

, p. 123 - 128 (2007/10/03)
Acylaminoēthyl esters of myristic, stearic, 12-hydroxystearic, oleic, ricinoleic and erucic acids have been synthesised at 60° using immobilised lipase as catalyst through the esterification of monoethanolamine with the respective fatty acid. Various surfactant properties of the synthesised esters have been evaluated and compared.
