What are the uses of glycol?
Ethylene glycol is widely used as antifreeze in automobile cooling systems and in the manufacture of human-made fibres, low-freezing explosives, and brake fluid. Ethylene glycol and some of its derivatives are mildly toxic.
What is polyethylene polypropylene glycol?
Polyethylene-polypropylene glycol is a liquid surfactant polymer. Poloxamer polymers are prepared by reacting propylene oxide with propylene glycol to form polyoxypropylene glycol. Ethylene oxide is then added to form the block copolymer.
What is mono propylene glycol used for?
Monopropylene glycol USP grade is used in food, beverage and animal feed, in pharmaceuticals as an excipient (inactive ingredient or carrier in a pharmaceutical product), in cosmetics and personal care products. The application of MPG USP for direct injections into the blood system is not allowed.
What is propylene glycol used for in food?

What is glycol used for in oil and gas?
Monoethylene Glycol (MEG) is used regularly in the oil and gas industry to prevent the formation of hydrates and resulting blockages in pipelines and equipment. The MEG is injected on the platform and processed onshore to recover a MEG concentration suitable for recycling back into the pipeline.
Is polypropylene glycol an alcohol?
What Is Propylene Glycol? Propylene glycol is a synthetic food additive that belongs to the same chemical group as alcohol. It is a colorless, odorless, slightly syrupy liquid that is a bit thicker than water.
Why is propylene glycol used in food?
Is propylene glycol safe for skin?
Is propylene glycol safe? Propylene glycol is tolerated well by the skin and shouldn’t cause redness or irritation. Propylene glycol is a penetration-enhancing humectant.
What is polyethylene glycol used for in medicine?
Polyethylene glycol 3350 is used to treat occasional constipation. Polyethylene glycol 3350 is in a class of medications called osmotic laxatives. It works by causing water to be retained with the stool. This increases the number of bowel movements and softens the stool so it is easier to pass.
Can you drink propylene glycol?
Yes, it is perfectly safe to consume foods containing propylene glycol (PG). Propylene glycol can only be toxic if used intravenously at high dosage or when applied to compromised skin (burns). Once ingested, PG is either excreted in the urine or is metabolized to lactic acid, a normal metabolic product.
