Galacturonic acid derivatives of formula (I); R1 being a linear or branched alkyl having from 2 to 22 carbon atoms, R being CH-CH(OH)-CO2R2 or -CH(OH)-CH-CO2R2, of which the carbon carrying the hydroxyl group is attached to the endocyclic oxygen atom. R2 is hydrogen, R1, an alkaline metal atom, an alkaline earth metal, or a quaternary ammonium group of formula (II) in which R3 to R6, independently of each other, are hydrogen, an alkyl having from 1 to 6 carbon atoms, or a hydroxyalkyl having from 1 to 6 carbon atoms. Said derivatives are useful as surface active agents. |
