Appearance of mono propylene glycol: Monopropylene glycol is a colorless, odorless, and clear liquid that dissolves in water.


Monopropylene glycol is placed in the category of emulsions.

The most important glycols are high intake, mono propylene glycol is produced from propylene oxide or ion exchange resin.


Application of monopropylene glycol


The use of monopropylene glycol in food industry, pharmaceutical industry, cosmetic and industrial applications, such as antifreeze and brake fluid, are used in vehicle brakes.

Mono propylene glycol MPG is used because of the stabilizing properties of insoluble liquids, solubility and preservatives that increase the shelf-life of foods.


Monopropylene glycol in the food industry is used to produce products such as beverages, cakes, biscuits, ice cream, cream, sauces, edible colors, vegetable oils, and so on.


Propylene glycol is used to help solubility and uniform distribution of taste, edible colors as solvents and flavors, in frying stability cakes, lubrication in oils, stabilization of the floor, and air conditioning in the cream.

food industry

It is used as a moisturizer and stable.

Cosmetic industry

It is used as a solvent and moisturizer.

Antifreeze production

Monopropylene glycol is used for antifreeze in automobiles, engines, boats, etc. due to its very low freezing point.

Monopropylene glycol is used as a hydraulic oil for hydraulic systems.

Mono-Propylene Glycol Consumption Notes

Propylene glycol, in accordance with the US Food and Drug Administration, is a safe substance that is considered as an additive in certain circumstances.


Propylene glycol may be exposed to high concentrations in prolonged periods, which may result in minor allergies and severe health problems.




Propylene glycol toxicity is very low, but persistent use of propylene glycol causes nausea.

Eating this substance causes temporary heart, liver and kidney problems


Skin contact with propylene glycol causes itching and irritation of the area. In this case, the skin should be washed with water.



Inhalation of propylene glycol in the long term leads to pain and discomfort in the chest.

Propylene glycol and other home-made volatile products have been identified as dangerous factors for asthma and other acute respiratory problems.


Eye contact:

If propylene glycol is in contact with the eyes in the form of liquid or vapor, it may cause mild allergic sensation and cause redness and pain in the eyes. In this case, the eyes should be washed quickly with cold water.

Note: Do not use any drops, creams, lotions, or medications for eye or skin inflammation with the help of propylene glycol without consulting an expert.
