Tween 65 is a non-ionic surfactant that functions as an emulsifier and stabilizer. It acts by reducing the surface tension between two immiscible phases allowing them to mix uniformly. Tween 65′s mechanism of action involves forming a protective layer around the dispersed phase, preventing coalescence and maintaining the stability of the emulsion. Tween 65 achieves this by adsorbing at the interface between the two phases, creating a barrier that inhibits the merging of droplets. This surfactant′s functional role includes enhancing the solubility of hydrophobic substances in aqueous solutions, facilitating the dispersion of particles, and improving the consistency of mixtures.
