Pharma Grade Liquid Paraffinโhighly refined mineral oil meeting USP/EP standardsโserves as a critical excipient, laxative base, and protective agent in oral, topical, and parenteral formulations. The Pharma Grade Liquid Paraffin market size is valued at USD 420 million in 2025 and is projected to reach USD 610 million by 2033, translating to a 5.4% CAGR over the forecast period. This steady growth outlook is underpinned by rising geriatric populations driving OTC laxative demand, expanding generic injectables in emerging markets, and tightening pharmacopeial purity rules that favor premium grades. Synonymous with medicinal white oil or pharmaceutical mineral oil, the scope covers only FDA-/EMA-certified lots sold to drugmakers, excluding technical or food grades.
