Title
(EN) BRANCHED AMINO ACID SURFACTANTS
(FR) TENSIOACTIFS D'ACIDES AMINÉS RAMIFIÉS
Abstract
(EN) The present disclosure provides derivatives of amino acids that have branched alkyl structures and surface-active properties. The amino acid can be naturally-occurring or synthetic, or they may be obtained via a ring-opening reaction of a lactam, such as caprolactam. The amino acid may be functionalized to form a compound that is surface-active and have advantageous surfactant characteristics. The compounds of the present disclosure have low critical micelle concentrations (CMC) as well as superior ability to lower the surface tension of a liquid.
(FR) La présente divulgation concerne des dérivés d'acides aminés qui ont des structures d'alkyle ramifiées et des propriétés tensioactives. L'acide aminé peut être d'origine naturelle ou synthétique, ou encore il peut être obtenu par l'intermédiaire d'une réaction d'ouverture de cycle d'un lactame, tel que le caprolactame. L'acide aminé peut être fonctionnalisé pour former un composé qui est tensioactif et qui présente des caractéristiques tensioactives avantageuses. Les composés selon la présente divulgation ont de faibles concentrations micellaires critiques (CMC) ainsi qu'une capacité supérieure pour abaisser la tension superficielle d'un liquide.
