solubledispersed

Solubledispersed is a term used in some scientific contexts to describe systems in which solutes are distributed as a solubilized dispersed phase within a continuous solvent. It is intended to capture a blend of features from true solutions, where solute molecules are molecularly dissolved, and conventional dispersions, where a dispersed phase exists as droplets or particles. In solubledispersed systems, solubilizing agents such as surfactants, cosolvents, polymers, or complexing agents are employed to increase apparent solubility and stabilize the dispersed entities.

These systems can take forms such as nanoemulsions, micellar dispersions, or polymeric nanoparticulate dispersions, depending on preparation methods and desired properties. Common preparation techniques include solvent-antisolvent precipitation, high-pressure homogenization, ultrasonication, and spontaneous emulsification, often guided by screening of co-solvents or surfactant systems to achieve targeted droplet sizes and stability.

Characterization focuses on droplet size distribution, zeta potential, rheology, and solubility measurements. Stability considerations include the effects of pH, ionic strength, temperature, and electrolytes; typical challenges involve coalescence, Ostwald ripening, and phase separation.

Applications are prominent in pharmaceuticals, where solubledispersed forms aim to enhance oral bioavailability of poorly soluble drugs, but the concept also appears in cosmetics, food, and agrochemicals. The term is not universally standardized, and related concepts are frequently described in the literature as solubilized systems, solubilized dispersions, or nanoemulsions.
