Zusammenfassung:The present invention relates to the use of an aminosulphonate compound corresponding to the following formula (I): R1R2N-CHR3-CHR4-CHR5-SO3− (I) where: *R1 is a preferably C2 to C24 alkyl or alkylamido radical; *R2 is an optionally hydroxylated alkyl radical; *R3, R4 and R5 are, independently of one another, H or OH; it being understood that at least one of the R3, R4 and/or R5 groups is OH, for stabilizing a foam, in particular a foam used to extract hydrocarbons in an underground formation.
