Nn-acyloxypropyl lysine methyl ester type and N, N-bis (n-acyloxypropyl) lysine methyl ester type compounds and use of the compounds as surfactants having antibacterial activity

摘要

The invention relates to novel compounds having an amphiphilic character (cationic, anionic, amphoteric and non-ionic), derivatives of n acyloxypropyl-type lysine amino acid according to general formula (I), which are intended to be used in the food, pharmaceutical and cosmetic industries as surface-active agents having a self-aggregating capacity and antimicrobial properties. Variations in activity are a function of the ionic nature of the final molecule, the number of fatty chains and the length thereof. The aforementioned products are prepared using a chemical synthesis method. The intermediate and final products are purified by means of liquid/liquid and liquid/solid extractions, crystallisations, cationic exchange chromatography and normal phase chromatography.
