micell
- A micell is a term often used in chemistry to describe an aggregate of surfactant molecules dispersed in a liquid colloid. These molecules arrange themselves in a spherical form in aqueous solutions, with the hydrophobic tails in the center and the hydrophilic heads facing the surrounding water. nounThe formation of a micell is crucial in the process of emulsification.In a soap solution, micells help to trap and remove dirt and oil from surfaces.
