Micelle formation occurs due to contaminated particles in water and fresh water. There are two departments involved: one is pure water and the other is impurities.

Soap also has two modes (organic tail and ionic head). The organic tail mixes and dissolves with the impurities but and oil or grease and ionic head dissolves in water.

Therefore, when the material to be cleaned is removed from the water, the impurities are removed by the soap molecules in the water. So, the soap cleanses by building closed structures.

Some solvents are similar to ethanol, in which the sodium salt of fatty acids does not dissolve, so you could not form such micelles.
