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.
