What does solubilize mean?
To solubilize is to cause a substance to dissolve in a liquid and become evenly distributed as a solution. The term is especially common in chemistry, biochemistry, pharmaceuticals, and materials science, where researchers and formulators use it to describe the deliberate transformation of a difficultly soluble compound into one that can be dispersed at the molecular level. It may also refer more broadly to increasing a substance's solubility through chemical or physical means. Unlike simply saying that something has dissolved, solubilize often emphasizes the process or intervention that makes dissolution possible. It is therefore frequently used with substances such as drugs, proteins, pigments, polymers, and other active ingredients. In ordinary discussion, the word has a distinctly specialized tone, while its causative structure allows for metaphorical use when describing how a proposal, market, or difficult issue is made more workable. The related terms soluble, solubility, solution, and solvent all reflect the same Latin root associated with loosening or dissolving.
verbTo cause a substance to dissolve in a liquid, making it form a solution. In technical contexts, it can also mean to increase a substance's solubility.
- To make a substance dissolve in a liquid or otherwise convert it into a homogeneous solution.
- To increase the solubility of a substance, especially through chemical treatment.
"The surfactant helps solubilize the active ingredient in the mouth spray."
"Heat and agitation were used to solubilize the protein in the buffer."
"The formulation uses cyclodextrin to solubilize the poorly water-soluble compound."
To solubilize is not merely to stir something into a liquid: it is to bring the substance into solution.

Where does solubilize come from?
The verb derives from Latin sōlubilis, meaning “soluble” or “able to be dissolved,” which developed from sōlvĕre, “to loosen, unfasten, or dissolve.” The English formation uses the suffix -ize, meaning “to make” or “to cause to become.” Its relatives include soluble, solubility, solution, and solvent, all of which reflect the same Latin root.

How solubilize is actually used
This is primarily a technical term used in chemistry, biochemistry, pharmacology, and related fields. It usually has a causative or transitive meaning, taking the substance being treated as its object.
Easily confused with solubilize
Dissolving can describe either the action that produces a solution or the resulting change in a substance, whereas solubilize specifically means to make a substance soluble.
