I keep seeing a strong opinion by some that encapsulation products don't encap anything. I have talked to a formulator before about this and he said that a primary function of any surfactant is to encapsulate soil. That is what their hydrophobic tail and hydrophilic head do. I googled surfactant and here is what I found.
"Many surfactants can also assemble in the bulk solution into aggregates. Examples of such aggregates are vesicles and micelles. The concentration at which surfactants begin to form micelles is known as the critical micelle concentration or CMC. When micelles form in water, their tails form a core that can encapsulate an oil droplet, and their (ionic/polar) heads form an outer shell that maintains favorable contact with water."
It is also my understanding that some surfactants hold the soil more effectivle than others.
