Beschreibung
Zusammenfassung:	The invention relates to a composition which comprises within an aqueous medium: - at least one ethoxylated alkylamine; and - at least one amphoteric or zwitterionic surfactant. The invention further relates to the use of said compositions as foaming compositions, in particular for enhanced oil recovery (EOR). L'invention concerne une composition qui comprend, au sein d'un milieu aqueux : - au moins une alkylamine éthoxylée; et - au moins un tensioactif amphotère ou zwitterionique. L'invention concerne par ailleurs l'utilisation de ces compositions à titre de compositions moussantes, notamment pour l'EOR.
