Abstract
Fatty acid based surfactants and methods for producing fatty acid based surfactants are described. The method includes reacting a fatty acid ester epoxide with a hydroxy acid, a hydroxy ester, a polyoxyalkyl diol, or a polyamine. Any remaining esters from the original fatty acid ester epoxide or hydroxy ester can optionally be hydrolyzed. Methods for making citric acid derived surfactants are also described.
