Figure 6: Schematic of polysorbate molecule and self-assembly into micelle and hydrogel. Polysorbates as amphiphile molecules (POE as hydrophilic segment and long, unbranched aliphatic tail of fatty acid as hydrophobic segment) (A, B),in aqueous solution, are oriented to form core-corona micelles (C). The micelles are crowded together in percolated network and ultimately in the gel state (D). POE, polyoxyethylene.
