Detailed Introduction of Mono Propylene Glycol (MPG)
📌 What is Mono Propylene Glycol (MPG)?
Mono Propylene Glycol (MPG) is a versatile, colorless, odorless, hygroscopic liquid widely used in various industries. It is classified as food-grade (USP, FCC, E1520), pharmaceutical-grade, and industrial-grade based on its purity levels and applications.
📌 Production Method & Raw Materials
Raw Materials:
Propylene oxide (main feedstock)
Water or catalysts for hydration
Production Process:
Hydration of Propylene Oxide (PO) under controlled temperature and pressure conditions.
Purification through distillation and filtration to meet food, pharma, and industrial-grade standards.
📌 Applications of Mono Propylene Glycol (MPG)
✔ Food & Beverage Industry (E1520, Food-Grade MPG)
Humectant & Moisturizer – Used in processed foods, bakery, and confectionery to retain moisture.
Solvent for Food Additives – Enhances flavor, color, and preservative dispersion in beverages.
Emulsifier & Stabilizer – Helps blend ingredients uniformly in dairy and sauces.
✔ Pharmaceutical & Personal Care Industry
Non-Toxic Solvent – Used in oral medications, cough syrups, and injectables.
Humectant in Skincare & Cosmetics – Retains moisture in creams, lotions, and shampoos.
Carrier for Active Ingredients – Used in topical and transdermal drug delivery systems.
✔ Industrial Applications
Antifreeze & Coolants – Used in HVAC systems, heat transfer fluids, and de-icing solutions.
Hydraulic & Brake Fluids – Acts as a lubricant and corrosion inhibitor.
Solvent in Paints & Coatings – Improves paint viscosity and dispersion.
📌 Key Benefits of MPG
✅ High Solubility – Easily dissolves in water, alcohols, and oils.
✅ Non-Toxic & Biodegradable – Safe for food, pharma, and cosmetic applications.
✅ Effective Humectant & Moisturizer – Prevents drying out of products.
✅ Excellent Solvent Properties – Enhances ingredient dispersion in formulations.
✅ Multi-Industry Applications – Suitable for food, pharma, cosmetics, and industrial use.
