Oleic acid diethanolamide

(Synonyms: OADA)

Oleic acid diethanolamide (OADA) is a non-ionic, biodegradable surfactant. Oleic acid diethanolamide reduces the surface tension of water, emulsifies free water in diesel fuel to form a stable emulsion, and can be loaded onto sulfonated polystyrene nanoparticles to enhance oil recovery. Oleic acid diethanolamide is one of the nematicidal secondary metabolites produced by Aspergillus flavus. Oleic acid diethanolamide can be used in studies related to biological control of root-knot nematodes, enhanced oil recovery, and diesel fuel emulsion stabilization.

In Vitro

Oleic acid diethanolamide (OADA) acts as a superior wetting agent, reducing water surface tension to 36.6 mN·m^-1 at a critical micelle concentration of 313 µM^[1].
Oleic acid diethanolamide (OADA) (0.01-2.0 mM) reduces water/mineral oil interfacial tension to ultra-low values, reaching an equilibrium IFT of 0.070 mN·m^-1 at 0.10 mM and a minimum of 0.017 mN·m^-1 at 2.0 mM^[1].
Oleic acid diethanolamide (OADA) (10-20 CMC) retention in polystyrene nanoparticles ranges from 19.8% to 56.2% (12.2 to 21.6 mg/g), with the highest surfactant loading achieved in 0sulf20 and 12sulf20 formulations^[1].
Oleic acid diethanolamide is a major secondary metabolite (301 g/mol) produced in cell-free culture filtrates of Aspergillus flavus (ON146363), comprising part of an 88% total fraction of nematicidal fatty acid derivatives^[2].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
