A method for the manufacture of N,N dialkylglycamine compounds of general formula R.sub.2 NR.sub.1 R.sub.3 (I) by reacting a secondary amine of general formula R.sub.2 NHR.sub.3 (II) in which R.sub.2 is a straight or branched chain alkyl or hydroxyalkyl group having from 1 to 4 carbon atoms and R.sub.3 is a residue from a monosaccharide, with an alkali metal or alkaline earth metal aliphatic sulphate, R.sub.1 SO.sub.4 M, in which R.sub.1 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.

The spectral, aggregation, and adsorption properties of amphiphilic metalcomplexes of alkylated N-methyl-D-glucamines and lanthanum nitrate and their mixture with hexadecyltrimethylammonium bromide were studied using IR, UV, and 1H NMR spectroscopy, tensiometry, potentiometry, and dynamic and electrophoretic light scattering. The parameters of aggregation and adsorption at the interface were determined
