| abstract |
The process of the invention is directed to the synthesis of cationic type surfactant compounds consisting of natural basic-character amino acids, and any of their homologs, suitably modified for the purpose of obtaining products having specific applications as antimicrobial (biocidal) agents. The process comprises a first step of esterification of an amino acid, and a second step of the condensation of a fatty acid chloride with an esterified amino acid derivative. Nontoxic reaction media and catalysts are used, and a final product free from impurities is obtained. The cost of the process of the invention is reduced from prior art processes due to the use of cheaper starting materials and simpler equipment. |
