The present article describes the preparation and the physico-chemicalproperties of novelbiocompatiblesurfactantsderivedfromalginate for applications in detergents and cosmetics. Controlled acid hydrolysis of commercially available alginatefrom Laminaria digitata gives saturated oligo-mannuronates on a multigram scale. Subsequent one-pot acid glycosidic bond hydrolysis, esterification and stereocontrolled
New dissymmetrical neutral-cationic or anionic-cationic alpha,omega-diamido bolaamphiphiles have been synthesized in which the polar headgroups are derived from alginate and glycine betaine and which exhibit monolayerlipidmembrane vesicles, large lamellae and rods.
