Green Synthesis, Composition Analysis and Surface Active Properties of Sodium Cocoyl Glycinate

Cocoyl glycine was synthesized directly from coconut oil and sodium glycinate in yield of 87%. IR, ESI-MS and LC/MS analysis results showed that cocoyl glycine consists of a series of acyl glycines with different acyl chain lengths, and the proportion of each component was consistent with the composition of fatty acids derived from coconut oil. The surface tension and the Critical Micelle Concentration (CMC) of corresponding sodium salt were evaluated. The result showed that sodium cocoyl glycinate reduced the surface tension of water to a minimum value of approximately 33 mN·m-1 at CMC of 0.21 mmol·L-1.
