Technical Abstract: Bio-based materials are those derived from plants or animals. In general, these materials comprise polar and non-polar chemical groups within the same molecule. In some biobased materials (e.g. vegetable oils), these chemical groups are found in distinctively separated regions. As a result, quite a number of these biobased materials are amphiphilic. Biobased amphiphiles could be readily soluble in polar (e.g. water) or non-polar (e.g. petroleum distillate) solvents. The resulting solutions show interesting surface and interfacial properties that are highly dependent on the detailed chemistries of the polar and non-polar groups of these amphiphiles. Surface and interfacial properties are important in the development of various industrial and consumer products from biobased materials. In this presentation, the surface and interfacial properties of solutions of vegetable oils in non-polar solvents are explored. Vegetable oils are obtained from a variety of plants and differ in the chemistries of both their polar and non-polar groups. The effect of chemical variations on the surface and interfacial properties of solutions of these biobased amphiphiles in non-polar solvents are discussed.
