An equation of state (EOS) was established to study the osmotic pressure and liquid‐liquid equilibria for micelle, colloid and microemulsion systems. The Carnahan‐Starling equation was used for the hard sphere repulsion. The Yukawa potential was used to describe both the attractive dispersion and the double‐layer repulsion. By using the established EOS, the osmotic pressures for charged colloid, uncharged micelle, uncharged and weakly charged microemulsion, the phase equilibria for uncharged micelle and charged colloid systems were studied.
