Frequently Asked Questions About Propylene Glycol


What is MPG Mono Propylene Glycol?

Propylene glycol is a synthetic food additive. MPG mono propylene glycol appears as a colorless, odorless, viscous liquid. Its chemical name is propane-1,2-diol, its molecular formula is C3H802, its e-code number is E1520, and its CAS number is 57-55-6. Owing to its multiple advantages, propylene glycol e1520 finds its way into various sectors including the food, cosmetics, and pharmaceuticals industry.

What Are Some Other Names For Propylene Glycol?

1,2-Dihydroxypropane, 1,2-Propanediol, PG 12, Methyl Glycol, Methyl ethylene glycol, Trimethyl glycol, Propylene glycol (PG), Monopropylene Glycol (MPG), 1,2-Propylene glycol, propylene glycol e1520

What Are the Types of MPG Mono Propylene Glycol?

According to the use of propylene glycol e1520, it can be divided into food-grade propylene glycol, pharmaceutical-grade propylene glycol, and industrial-grade propylene glycol.

What IS MPG Mono Propylene Glycol Made From?

1. Propylene Oxide Hydration: Propylene oxide is reacted with water to produce 1,2-propylene glycol and a small amount of an undesirable byproduct, propylene glycol monomethyl ether (PGME). This method is the most common way to produce PG and is widely used in commercial production.

2. Propylene Glycol from Glycerin: Glycerin is reacted with propylene oxide to produce mpg mono propylene glycol and water. This method is often used as a way to recycle glycerin that is produced as a byproduct of biodiesel production.

3. Propylene Glycol from Propane: Propane is oxidized to produce propylene oxide, which is then hydrated to produce propylene glycol liquid. This method is less common than the first two methods but is still used in some commercial production.

What Are MPG Monopropylene Glycol Uses?

Propylene glycol liquid is a chemical compound monopropylene glycol uses in many different products are broad from food to medicine to personal care items.
# Food and Beverage Industry – E1520 food additive is commonly used as a food additive since it is safe for human consumption. Propylene glycol in food is used as a humectant, which helps to retain moisture in foods and prevent them from drying out. Propylene glycol is also used as a solvent for food colors and flavors.

# Cosmetics and Personal Care Industry – MPG mono propylene glycol is used in cosmetics and personal care products as a humectant, solvent, and viscosity control agent. It is commonly found in shampoos, conditioners, deodorants, lotions, and toothpaste.

# Pharmaceutical Industry – Propylene glycol ingredients are used in the pharmaceutical industry as a solvent for active ingredients in medications. Propylene glycol usp is also found in topical creams, ointments, and gels as a humectant and viscosity control agent.

# Industrial Applications Propylene glycol e1520 is used as a coolant in refrigeration systems and as a lubricant in hydraulic systems. It is also employed as an antifreeze for heat transfer fluids in industrial applications.

#Antifreeze and Deicing Agent – 1,2-Propanediol has the ability to lower the freezing point of water which makes it an ideal antifreeze and deicer. Propylene glycol (PG) is commonly used in aircraft deicing fluids and automobile anti-freeze.

Is Propylene Glycol Recognized By the FDA?

The U.S. Food & Drug Administration (FDA) has classified propylene glycol (MPG) as a safe food ingredient, known as Generally Recognized As Safe (GRAS). This means that it is considered safe for its intended uses in food and has been deemed acceptable for consumption. With its GRAS status, consumers can feel confident in using propylene glycol ingredients in their food products.

Where Can You Buy Propylene Glycol?

Looking to purchase MPG mono propylene glycol? You may be able to buy propylene glycol at local stores, but the convenience of online shopping may be a better option for you. There are various quantities and purity levels available, including food-grade MPG and monopropylene glycol USP grade. So you can easily find exactly what you need.
