TI  - Small-Angle Neutron Scattering Insights into 2-Ethylhexyl Laurate: A Remarkable 
      Bioester.

AB  - Commercial (protiated) samples of the "green" and biodegradable bioester 
      2-ethylhexyl laurate (2-EHL) were mixed with D-2-EHL synthesized by hydrothermal 
      deuteration, with the mixtures demonstrating bulk structuring in small-angle 
      neutron scattering measurements. Analysis in a polymer scattering framework 
      yielded a radius of gyration (R(g)) of 6.5 A and a Kuhn length (alternatively 
      described as the persistence length or average segment length) of 11.2 A. Samples 
      of 2-EHL dispersed in acetonitrile formed self-assembled structures exceeding the 
      molecular dimensions of the 2-EHL, with a mean aggregation number (N(agg)) of 3.5 
      +/- 0.2 molecules across the tested concentrations. We therefore present structural 
      evidence that this ester can function as a nonionic (co)surfactant. The available 
      surfactant-like conformations appear to enable performance beyond the low 
      calculated hydrophilic-lipophilic balance value of 2.9. Overall, our data offer 
      an explanation for 2-EHL's interfacial adsorption properties via self-assembly, 
      resulting in strong emolliency and lubricity for this sustainable ester-based 
      bio-oil.
