MONOPROPYLENE GLYCOL: A VERSATILE INGREDIENT ACROSS INDUSTRIES
🧪 What is Monopropylene Glycol?
Monopropylene Glycol (MPG)—also known as Propylene Glycol (PG) or 1,2-propanediol—is a clear, colorless, odorless, and slightly viscous liquid with excellent water solubility. It is a synthetic organic compound derived from petroleum-based propylene oxide, and is classified as a diol, meaning it contains two alcohol (-OH) groups.
MPG is prized for its:
- Low toxicity
- Solvent properties
- Humectant capabilities
- Compatibility with many substances
Available in multiple grades (USP/EP, Food, Industrial, Cosmetic), it serves as a solvent, stabilizer, carrier, antifreeze, and humectant across sectors.

🏭 Applications of Monopropylene Glycol
MPG is a true multi-purpose chemical, featured in a wide array of industries:
1. Food & Beverage Industry (Food Grade MPG)
Monopropylene Glycol is E1520, an approved food additive and carrier. Its key roles include:
- Humectant: Retains moisture in baked goods and candies
- Carrier solvent: For flavors, colors, and emulsifiers
- Antifreeze: In food cooling systems (non-toxic alternative to ethylene glycol)
✔️ Safe for ingestion in regulated amounts
✔️ Does not alter taste or odor
2. Pharmaceutical & Personal Care
MPG is widely used in medicines, oral care, skincare, and hair products, acting as:
- Solvent for active ingredients
- Humectant for moisture retention
- Stabilizer in emulsions and creams
- Carrier in drug formulations (especially for topical or oral liquids)
✔️ Found in syrups, gels, creams, toothpaste, and more
✔️ Classified GRAS by the FDA for pharmaceutical uses
3. Cosmetics & Toiletries
Monopropylene Glycol is a common ingredient in:
- Moisturizers and lotions
- Shampoos and conditioners
- Deodorants
- Makeup products
Its hydrating properties, non-irritant profile, and ability to blend water and oils make it ideal for personal care formulations.
4. Industrial & Chemical Applications (Technical Grade)
MPG is extensively used in:
- Antifreeze and de-icing fluids (less toxic than ethylene glycol)
- Heat transfer fluids in HVAC systems
- Plasticizer in resins and coatings
- Solvent for inks, dyes, and industrial cleaners
- Hydraulic fluids and brake fluids
✔️ Biodegradable and lower environmental impact
✔️ Efficient for closed-loop heat transfer systems
5. E-Cigarettes & Vaping Liquids
MPG is a primary base solvent in vape juices, helping to:
- Create visible vapor clouds
- Dilute nicotine and flavors
- Ensure consistency
Its high purity and low toxicity make it a safe inhalable carrier when regulated properly.
🌍 Environmental and Safety Profile
- Biodegradable and low ecological risk
- Non-carcinogenic and non-mutagenic
- Generally safe when handled with standard chemical precautions
⚠️ Storage & Handling:
- Store in sealed containers away from strong oxidizers
- Keep in a cool, dry, and well-ventilated area
- Avoid prolonged contact with skin and eyes
- Use gloves and eye protection during bulk handling
