The alkyl galactarates of formula : in which R1 is alkyl or alkenyl having from 1 to 22 carbon atoms and, or else R2 is, when it is different from R1, hydrogen, alkyl or alkenyl having from 1 to 22 carbon atoms, and when it is identical to R2, alkyl or alkenyl having from 7 to 22 carbon atoms, and R3 is hydroxy, or else R3 forms with R2 a valence bond between the atoms which disturb them, and their salts with alkali, alkaline-earth metals or d ammonium are surfactants. |
