Polyethylene Glycol (PEGs & MPEGs)

Polyethylene Glycol Wax (PEGs), Methoxy Polyethylene Glycol (MPEGs)

Pharcos employs a highly controlled manufacturing batch production for Poly ethylene Glycols (also known as Polyethylene Glycol wax) that meet the most stringent specifications including various Pharmacorpia standards like (IP, USP & NF).

MPEG (Methoxy Polyethylene Glycol) is also synthesized by Pharcos. Methoxy polyethylene glycols are additional polymers of methanol and ethylene oxide. Methoxy polyethylene glycols are come in average molecular weight range from 350 to 5000.

All MPEGs are identified by a number that represents their average molecular weight.

PEGs & MPEGs are essentially non-toxic, stable and versatile solvents that find application in the oral care, paint, pharmaceutical, cosmetic, resin, textile, plastic, ceramic and automotive industries.

Polyethylene Glycols

As a manufacturer of Polyethylene Glycols several advantages of Polyethylene Glycol (PEG) over other laxatives have been established. It is soluble in water, exhibits a long shelf life, and does not undergo biodegradation. Moreover, PEG is non-toxic and has good skin compatibility.

Properties and Applications of Polyethylene Glycols

A polyethylene glycol (PEG) is a water-soluble polymer of ethylene oxide. Its chain length and molar mass determine its pharmacological profile. While most PEGs are insoluble in water, the molecular weight of the polyethylene glycol chain affects its physical properties. Hence, it is available in several forms depending on the initiator used. The lowest molecular weight PEG is methoxy-PEG, which has a neutral or slightly negative surface charge.

The most commonly used polyethylene glycol products are pharmaceuticals, food and chemicals. Its properties make it a versatile polymer that has a wide range of applications. PEG molecules can be any length and number of repeating units. Short chains of low molecular weight are colourless liquids, while long chains have high molecular weights. Both forms are highly soluble in water and are nontoxic. The chemical’s high molecular weight forms are often used as a mass spectrometry internal calibration compound.

Methoxy Polyethylene Glycol (MPEG)

We as a leading exporter of MPEGs know that Methoxy Polyethylene Glycol is soluble in many polar solvents. They are readily miscible with water. They are solid, so their solubility decreases with increasing molecular weight. Therefore, MPEGs are used in a variety of applications, including paints, inks, and polymer modification.
