Amphiphilic properties of a polymerized glycolipid surfactant

“…The investigation of carbohydrate derived fluorinated amphiphiles has been expending in the recent years [61]. Several works describing the preparation of fluorinated alkyl amides [66][67][68][69][70][71][72][73], ureas [74,75] or carbamates [76][77][78][79][80] derived from carbohydrates have been published.

The constant need for products obtained from natural raw materials instead of non-renewable petroleum feedstocks has led to a lot of effort on developing new "natural" surfactants. Most important among these are surfactants derived from carbohydrates and plant oils such as coconut or palm kernel. These compounds find applications in cosmetics, food manufacture, biology, etc, and some of them are studied for their liquid crystalline properties.

“…We point to the relatively small aggregation numbers of the amino acid and dipeptide terminated PS as being an important factor in governing probe solubilization because previous research has shown that when the polymer aggregation number is large, PS have a greater solubilizing power than corresponding surfactant micelles. 38 Boyer et al examined the water solubility of 3-acetylphenanthrene in solutions of micellar and polymeric N-(undec-10-enyl)lactobionamide surfactants. 38 At all concentrations the polymeric solutions provided a greater solubility of the hydrophobic solute.…”

Pulsed field gradient NMR spectroscopy was used to investigate the association of toluene, chlorobenzene and benzyl alcohol with amino acid and dipeptide terminated polymerized surfactants (PS). The diffusion coefficient for each probe was measured in the presence and absence of the polymers and the mole fraction of bound probe molecules, f b , was calculated. For all solutions investigated, the probes associated more strongly with unpolymerized surfactant micelles than with corresponding PS. For example, the toluene f b values for association with sodium undecanoyl valinate micelles and the PS poly(sodium undecanoyl valinate) were 0.88 and 0.15, respectively. The relatively weak probe-polymer association was attributed to the polarity and fluidity of the polymers' hydrocarbon cores and to the fact that these PS have smaller aggregation numbers than the corresponding unpolymerized surfactant micelles.
