General description

Dibutyl phthalate (DBP) is a plasticizer commonly used in the formulation of biologics to improve the flexibility and stability of polymeric materials. It plays an essential role in the production of drug delivery devices and packaging for biologics. By enhancing the physical properties of polymers, DBP contributes to the reliability and performance of biologic products, particularly those in extended-release or controlled-release systems.

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.
