General description

Plastic additive 3 serves as a plasticizer, improving the performance of polymeric materials used in biologic drug delivery systems. As a USP reference standard, it is critical for maintaining the stability of biologic packaging materials, ensuring that these products retain their structural integrity during storage and use, preventing degradation of the biologic inside.

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.
