Emulsifying SurfactantBlends oil and water phases into stable mixtures
SCIENTIFIC ANALYSIS
// Evidence: Emulsifying surfactants enable creation of stable oil-in-water or water-in-oil emulsions by positioning at oil-water interface, reducing interfacial tension. HLB (hydrophilic-lipophilic balance) determines emulsion type: HLB 3-6 for W/O, HLB 8-18 for O/W emulsions. Examples include polysorbate 80, ceteareth-20, glyceryl stearate. Mechanism involves forming interfacial film preventing droplet coalescence. Often used in combinations with co-emulsifiers (fatty alcohols) creating lamellar structures for enhanced stability.
