General description

Find answers to frequently asked questions on USP products in USP FAQs.

Padimate O, an ester of para-aminobenzoic acid, is used in biologic and pharmaceutical formulations, particularly in sunscreens and topical products. It acts as a UV filter, providing protection against harmful ultraviolet radiation. In biologic product development, Padimate O helps ensure the stability and safety of topical biologics, contributing to the effectiveness of these formulations in protecting the skin.

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.
