A method for the manufacture of N,N dialkylglycamine compounds of general formula R₂NR₁R₃(I) by reacting a secondary amine of general formula R₂NHR₃ (II) in which R₂ is a straight or branched chain alkyl or hydroxyalkyl group having from 1 to 4 carbon atoms and R₃ is a residue from a monosaccharide, with an alkali metal or alkaline earth metal aliphatic sulphate, R₁SO₄M, in which R₁ is a straight or branched chain alkyl or alkenyl group having from 8 to 24 carbon atoms.
The betaine, suphobetaine and N-oxidised derivatives of (I) are provided for use as mild surfactants.
