Three families of anionic sugar-based surfactants bearing a sulfate functional group on the primary position of a monosaccharide were synthesized and their physicochemical properties were compared. The first family corresponds to 6-sulfate derivatives of commercially available octa- and dodecyl β-D-gluco- and galactopyranosides. The second and the third families contain an amide linker between the sulfated monosaccharide (galactose, glucose or xylose) and the hydrophobic alkyl chain. Twelve of the as-synthesized anionic glycolipids, including nine novel sulfated compounds, were investigated for their surface activity at the air/liquid interface and for their self-assembling properties. These sugar-based surfactants show surface properties similar to those of commercial anionic surfactants (SDS and SLES) with good ability to reduce surface tension. The obtained results confirm the interest in these new bio-based molecules for potential substitution of anionic surfactants in various formulations.

A series of N-substituted aldonamodes has been synthesized.Some of these compounds form a thermotropic lamellar mesophase in which molecules in the trans-configuration are arranged in monolayers stabilized by hydrogen bonding and hydrophobic interactions.X-ray diffraction studies have shown that a molecular arrangement of this type exists in the crystalline solid of N-decylribonamide.The relationship between the mesogenic properties and the molecular structures of these compounds is discussed (with reference to the length, branching and cyclisation of the aldonic residue and of the hydrocarbon chain).
