Here, σ is the surface tension of a given solute in an aqueous solution and σw is the surface tension of pure water at 20 °C (72.8 mN m -1 ). We note that this equation disregards the bulk to surface partitioning of solute particles, which directly influences the Raoult effect and can raise the critical supersaturation ratio, eclipsing any potential lowering due to surface tension depression. However, when the solute composition in the particle bulk is comprised primarily of inorganic species, bulk-to-surface partitioning may be limited and the solute concentration in the bulk remains constant. Additionally, the formation of an organic crust layer over an inorganic aqueous core via liquid-liquid phase separation, a process attributed to oligomeric compounds like those studied here, may also limit surface-to-bulk partitioning. Based on these considerations, we make the assumption in this idealized study that the effects on the critical supersaturation ratio are primarily due to surface tension depression.
