Other possible phases include mixtures of water and highly polymerized substances, or water with non-ionic surfactants.
Krafft temperature, the minimum temperature at which surfactants form micelles
Hydrocarbon-based surfactants are compounds that are amphiphilic (or amphipathic), having a hydrophilic, water interactive 'end', referred to as their 'head group', and a lipophilic 'end', usually a long chain hydrocarbon fragment, referred to as their 'tail'.
Poractant alfa, Calfactant, Beractant are the types of natural surfactants commercially available in the United States.
Macroemulsions in latex paint are inherently unstable and phase separate, so surfactants are added to lower interfacial tension and stabilize polymer particles to prevent demulsification.
