• interaction of the alkyl chains. Keywords: dirhamnolipid ester; gemini surfactant; rheology; reverse wormlike micelle (RWLM); Introduction Surfactants have both hydrophilic and hydrophobic groups and are therefore amphiphilic molecules. Due to their unique molecular structure, surfactants are essential

• dirhamnolipid esters with a different alkyl chain length, whereas a different mechanism leads to the destruction of the network-like structure for the gemini surfactant 7. For 7, the transition from the solid to the liquid state occurs at much lower deformation of γ = 12.6% (δ = 45°). Frequency sweep To

• (DSC) analysis was performed to obtain some more information about the interactions that are responsible for the gel-like behavior. Five heating and cooling cycles were recorded for the gemini surfactant 7/toluene system (5 wt %). The DSC curves (Figure S5 in Supporting Information File 1) once again
