Abstract

The present disclosure relates to glycolipid compositions, methods for making glycolipid compositions, and their uses thereof. Glycolipid compositions can be prepared via yeast-mediated catalyzed reaction, and exhibit excellent surfactant properties having high corrosion inhibition performance, good reducing surface tension efficiency. Processes of the present disclosure can provide glycolipid compositions having one or more of: a ratio of lactonic glycolipids to glycolipid acylic esters is from about 1:10 to about 10:1, a molecular weight of from about 400 g/mol to about 10,000 g/mol, a corrosion rate of carbon steel from about 0.5 MPY to about 100 MPY at room temperature and at pH 4-6. Furthermore, aqueous solutions of the glycolipid compositions of the present disclosure can have a surface tension of from about 20 mN/m to about 80 mN/m.
