Propylene Glycol (CAS 57-55-6) — Applications Across Pharmaceutical, Food, Personal Care, and Industrial Sectors
Propylene Glycol (IUPAC: 1,2-Propanediol; also known as Monopropylene Glycol or MPG; CAS 57-55-6) is a colorless, viscous, hygroscopic liquid that is fully miscible with water and many polar organic solvents. Nexal Inc. supplies various grades at ≥99.85% assay to support formulation work in pharmaceutical, food, personal care, and industrial settings across North and Latin America (propilenglicol).
• Pharmaceutical Formulation
Used as a solvent, humectant, and co-solvent in oral, topical, and selected formulations.
End Products: oral syrups and suspensions, topical creams and ointments, soft gelatin capsule fills, nebulizer solutions, ophthalmic preparations.
• Food & Beverage Ingredient
Propylene glycol functions as a humectant, solvent, and carrier for flavors, colors, and antioxidants.
End Products: baked goods, frozen desserts, beverage concentrates, flavor and color carrier systems, condiments and seasoning blends.
• Personal Care & Cosmetics
Acts as a humectant, solvent, and viscosity modifier in skin and hair care formulations, supporting product texture and uniformity.
End Products: facial moisturizers and serums, body lotions, shampoos and conditioners, oral care formulations, color cosmetics, deodorants.
• Industrial Solvent, Heat Transfer & Polymer Feedstock
A substantial share of global propylene glycol output is consumed as a feedstock for unsaturated polyester resin (UPR) manufacturing. Its low toxicity profile, high boiling point, and complete water miscibility also support use in low-toxicity coolant and de-icing systems.
End Products: unsaturated polyester resin (UPR) feedstock, polyurethane polyol component, low-toxicity heat transfer fluids and HVAC coolants, aircraft and runway de-icing concentrates, theatrical fog and humidification systems.
Core Technical Profile: ≥99.85% assay across various grades; low Pt-Co color (≤10) supporting clear formulations; complete miscibility with water and many polar organic solvents; broad liquid range with low vapor pressure; recognized low-toxicity profile across the major use categories above. Each shipment is accompanied by a current SDS and Certificate of Analysis.
