Description

1-Propanol (CAS 71-23-8 ), also known as propylic alcohol, is a short-chain primary alcohol used as a solvent and carrier across pharmaceutical, cosmetic, and industrial manufacturing. Its controlled evaporation rate and broad solvency make it a practical choice where ethanol or isopropanol may be technically or regulatory mismatches for specific industrial processes. In pharmaceutical manufacturing, it functions as a process solvent for active ingredient extraction, recrystallization, and coating formulations to ensure high-quality chemical outputs. Printers and packaging converters use it as a solvent in flexographic and gravure ink systems, where it supports pigment dispersion and controlled drying on various film substrates. In personal care, it serves as a carrier solvent in fragrance concentrates and topical formulations requiring a clean evaporation profile for consumer-facing cosmetic products. At the flavor level, it is approved under FEMA 2928 as a flavoring agent and solvent for flavor delivery in a wide range of food and beverage applications. Pharmaceutical-grade material is available to USP and Ph. Eur. specifications; technical-grade is standard for industrial solvent applications and bulk manufacturing. Food-grade supply aligned with FCC specifications is available for flavor and food processing end uses, supplied in drums, IBCs, and bulk tanker quantities.
