Understanding Pharmaceutical Solvent Purity Standards: IPA & Propylene Glycol

Chemical solvents used in active pharmaceutical ingredient (API) synthesis, topical formulations, and cleanroom disinfection must meet stringent pharmacopeial standards (IP/USP/BP/EP).

High Purity Isopropyl Alcohol (IPA)

Electronic and pharmaceutical grade Isopropanol features 99.8% minimum assay with negligible non-volatile residue (<0.001%), ensuring no trace contaminants remain upon evaporation during medical device cleaning.

USP/IP Grade Propylene Glycol

Propylene Glycol serves as a safe humectant, co-solvent, and preservative in oral liquids and topical creams. High purity ensures zero heavy metal contamination and consistent viscosity control.
