What is 1-propanol?
1-Propanol (CAS 71-23-8), also known as propylic alcohol, is a short-chain primary alcohol used as a solvent and carrier in pharmaceutical, cosmetic and industrial manufacturing.
Where is 1-propanol used?
- Pharmaceutical manufacturing: process solvent for active ingredient extraction, recrystallization and coating formulations
- Printing and packaging: solvent in flexographic and gravure ink systems, supporting pigment dispersion and controlled drying on film substrates
- Personal care: carrier solvent in fragrance concentrates and topical formulations
- It is approved under FEMA 2928 as a flavoring agent and solvent for flavor delivery in food and beverages.
Good to know: Its controlled evaporation rate and broad solvency suit processes where ethanol or isopropanol are technical or regulatory mismatches.
Commercial specifications
- Technical grade for industrial solvent use and bulk manufacturing
- Drums, IBCs and bulk tanker quantities
