Claims17
A derivatized surfactant compound having the following General Formula:
- wherein X is a C2-C22 fatty amide derived from a fatty acid or a biosurfactant comprising a fatty acid moiety, Y comprises an amino acid-derived functional group, and Z1 and Z2 are independently a hydrogen or alkyl group.
A method for producing a derivatized surfactant compound with stability at pH 2-12, said compound having the following structure:
- wherein X is a C2-C22 fatty amide derived from a fatty acid or a biosurfactant comprising a fatty acid moiety, Y comprises an amino acid-derived functional group, and Z1 and Z2 are independently a hydrogen or alkyl group,
- the method comprising coupling a biosurfactant or fatty acid-containing substrate X′ with an amide Y′ comprising one or more amino acid side chains to produce an amino-acid functionalized surfactant XY, and
- either before, during or after coupling of XY, reacting Y′ or XY with a reducing agent Z′ to reduce any ester groups existing therein to an alcohol.
A method for improving the pH stability of an amino acid ethyl ester, the method comprising converting the amino acid ethyl ester to an amino alcohol.
