They had better stability than the existing organogelators C16AG and dextrin palmitate. While these existing organogelators stabilize the emulsified state by increasing the oil's viscosity, we believe that the C-GL series stabilizes the emulsified state by increasing the oil's viscosity moreover some interaction with water. In other words, we speculate that the carbonyl oxygen atom at the γ-lactone, which is characteristic of C-GL series, improves the affinity with water and stabilizes the emulsified state. Among these, C16GL and C18GL were found to gelate oil at relatively low concentrations and high emulsion stability and are expected to be applied in the cosmetics and painting fields.
