The system can reduce its entropy further, whilst incorporating more water, by interposing more water molecules between DIPAs, forming reverse micelles. In this arrangement, the water molecules also benefit from forming hydrogen bonds with each other, making this a low-energy way of accommodating excess water beyond one-per-DIPA and allowing higher water concentrations in the DIPA-rich phase at little or no energetic cost because the water can form a hydrogen bonded network with itself inside the reverse micelle.
