Mono Propylene Glycol – High-Purity MPG

Mono Propylene Glycol (MPG), also known as Propane-1,2-diol, is a clear, slightly viscous liquid derived from propylene oxide. Recognized for its low toxicity, solubility, and ability to retain moisture, it is widely used in industries ranging from food and pharmaceuticals to cosmetics and antifreeze formulations.

Cavin Resource offers USP, FCC, and industrial-grade MPG, tailored for a wide variety of applications including humectants, solvents, heat transfer fluids, and hydraulic fluids. Our bulk supply ensures consistent quality, regulatory compliance, and worldwide shipping, including CIF delivery.

We serve wholesale buyers with custom packaging, documentation (MSDS, COA), and competitive pricing.

⚙️ Production Method

Hydrolysis of Propylene Oxide

1. Propylene oxide undergoes non-catalytic hydrolysis using water under heat.

2. The reaction yields mono-propylene glycol as the primary product, along with small amounts of dipropylene glycol.

3. Final product is purified by distillation and adjusted for food, pharma, or technical grade standards.

❓ Frequently Asked Questions (FAQs)

1. Is Mono Propylene Glycol safe for food and pharmaceutical use?

Answer: Yes, MPG is approved by the FDA (E1520) and complies with USP/FCC standards for food and pharmaceutical applications.

2. What is the difference between Mono and Di Propylene Glycol?

Answer: Mono Propylene Glycol is the primary product with lower molecular weight, used in food/pharma; Dipropylene Glycol is a by-product more common in industrial applications like perfumes or antifreeze.

3. Can MPG be used in heating or cooling systems?

Answer: Yes, its low freezing point and chemical stability make it an excellent choice for closed-loop heat transfer and HVAC systems.

4. Does MPG have environmental impacts?

Answer: It is biodegradable and has low aquatic toxicity, making it an environmentally safe alternative to more toxic glycols like ethylene glycol.
