General description

Diethyl phthalate (DEP) is a widely used solvent and plasticizer in biologic formulations, enhancing the stability and flexibility of polymeric materials. It is commonly incorporated into drug delivery systems, ensuring that biologics are effectively released and administered to patients. DEP′s role in reducing polymer brittleness and enhancing formulation characteristics makes it an essential excipient in the biologics industry.

The United States Pharmacopeia (USP) provides quality standards for biologics to ensure their safety, efficacy, and quality throughout the manufacturing process. These standards assist manufacturers in adhering to regulatory requirements and help safeguard public health by reducing risks associated with biologics.
