Overview
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.
