Traditional ionic or non-ionic surfactants stabilize oil-in-water emulsions principally by adsorbing and forming lamellar liquid crystalline layers at the emulsion interface requiring usage levels of 3-7% of surfactant. The hydrophilic-lipophilic balance (HLB) of the oil phase and surfactant must be carefully matched to insure good emulsion stability. Acrypol polymeric emulsifiers have a small oil lipophilic (oil-loving) portion and in addition to a large hydrophilic (water loving) portion so it is used as primary emulsifiers in oil-in-water emulsions. The lipophilic portion adsorbs at the oil-water interface, and the hydrophilic portion swells in the water forming a gel network around oil droplets to provide exceptional emulsion stability to a broad range of oils. It is very stable structure.
