Solubilization refers to the phenomenon that the solubility of insoluble or insoluble organic matter can be greatly increased when the concentration of non-surfactant in aqueous solution reaches the critical micelle concentration.
The size of the solubilization capacity is often expressed in solubilization amount (the amount of soluble organic matter per mole of surfactant, in grams). The solubilization amount is related to the structural characteristics of surfactants and solubilized matter, temperature, the addition of organic and inorganic additives and other factors. Solubilization plays an important role in emulsion polymerization, micellar displacement, washing and some physiological processes.
Characteristics of solubilization
The "dissolution" of solubilization is distinguished from the dissolution of organic matter in a mixed solvent. Organic matter dissolved in the mixed solvent and inorganic matter dissolved in the related solvent are dissolved in the form of molecules and ions in the solvent molecules. The "dissolution" of the increased bridge section is that the molecular group with a much larger than the molecule is "surrounded" by the surfactant micelle, and then the whole is dissolved in the solvent. Solubilization "dissolution" seems to be similar to emulsification, but it is still different from emulsification. The e delay of milk is a thermodynamically unstable polyphase dispersion system without a solution-sensitive body dispersed in water (or another liquid), while the system formed by solubilization is a thermodynamically stable homogeneous system.
