Pemulen™ Polymeric Emulsifiers
Pemulen™ polymeric emulsifiers are high molecular weight, cross linked copolymers of acrylic acid and a hydrophobic comonomer. They stabilize oil-in-water emulsions, where the lipophilic (hydrophobic) portion of the polymer 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. They are used as stabilizers of oil-in-water systems, with up to 50% oil loading possible at typical use levels of 0.15 to 0.4%.
