The present invention provides new saccharide surfactants. The saccharide surfactants include diblock and triblock saccharide surfactants. The diblock saccharide surfactants have a hydrophobic segment bonded to a hydrophilic head group, that is a saccharide chain. The triblock saccharide surfactants have a hydrophobic segment bonded to two hydrophilic saccharide chains. The hydrophobic segments of the diblick and triblock saccharide surfactants comprise at least one alkyl chain having 5 to 20 carbon atoms, preferably 6 to 18 carbon atoms, more preferably 8 to 18 carbon atoms. The saccharide head groups/chains include monosaccharides, disaccharides, and oligosaccharides and have an average weight molecular range of less than 4000. Preferably the saccharide head group/chain comprises 2 to 12 sugar residues. Preferably the saccharide head groups are linked to the alkyl chains by an amide group.
