Pemulen™ polymeric emulsifiers are high molecular weight copolymers of acrylic acid and C10-C30 alkyl acrylate crosslinked with allyl pentaerythritol. These pharmaceutical excipients provide effective emulsification properties to form stable oil-in-water emulsions. They contain both hydrophilic and hydrophobic portions and serve as excellent gel forming polymers, creating a network around suspended oil droplets and providing exceptional emulsion stability, often without the need for additional surfactants. Ideal for use in topical drug delivery, transdermal drug delivery, and other mucosal applications, such as ophthalmic drug delivery. Pemulen polymers help create low irritancy creams and lotions, providing optimal aesthetics, feel, and drug penetration into the membrane, as well as efficacious, non-irritating emulsion eye drops. They also provide viscosity building and high yield value to allow for suspension and stabilization of insoluble particulates.
