Pemulen™ polymeric emulsifiers are high molecular weight, copolymers of acrylic acid and C10-C30 alkyl acrylate crosslinked with allyl pentaerythritol. They are offered as fluffy, white powders and are primarily used to form stable oil-in-water emulsions. Pemulen™ polymers contain both hydrophilic and hydrophobic portions within the molecule. The hydrophobic portion of the polymer adsorbs at the oil-water interface, and the hydrophilic portion swells in the water forming a gel network around the oil droplets to provide exceptional emulsion stability.
Pemulen™ polymers form stable oil-in-water emulsions without the need for any additional surfactants. Therefore, they are ideal for developing low irritancy lotions and creams with elegant skin feel. Pemulen™ polymers provide viscosity building and high yield value to allow for suspension and stabilization of insoluble materials and particulates.
