Multiscale molecular dynamics simulation study of polyoxyethylated alcohols self-assembly in emulsion systems

•Multiscale simulations are performed to study nonionic-surfactant-based systems.•Degree of branching and chain length affect the self-assembly of surfactants.•Co-surfactants facilitate formation of disordered network aggregation in the quaternary systems.•A normalized packing parameter is proposed to quantify the surfactant aggregation.
