Product definition
Polylene glycol (PEG) is a polymer made of ethylene glycol molecules connected by a chemical reaction. It has a linear structure, in which the ethylene glycol unit (C2H4O) is repeatedly linked together to form a long chain. The properties of polyethylene glycol can be adjusted by controlling the molecular weight (the degree of polymerization, also known as the length of the polymer), to obtain different chemical and physical properties.

Product Functional Category and Applications

1. PEG can help make the drug more soluble, so people are more effective when they take it. It can also help protect the drug, releasing it slowly in the body, which is very helpful for some long-term treatments.

2. PEG can make cosmetics smoother and easier to apply to the skin. It also keeps the skin moist and makes it feel softer.

3, polyethylene glycol can be used as a lubricant, so that some mechanical parts in the operation of more smoothly. It can also be used on medical devices to make the examination and surgery more smoothly.

4. In the food processing process, polyethylene glycol can be used to improve the texture and taste of food. It can also help keep the food moist and extend its shelf life.

常见问题 （Frequently Asked Questions）

Molecular weight, viscosity, freezing point and dosage forms

What is the difference between polyethylene glycol 600 pharmaceutical grade and PEG 400?

Both are liquids at room temperature. PEG 600 has a higher average molecular weight, higher viscosity and a freezing point of about 15 to 25 °C, so it may turn hazy or semi-solid in winter. PEG 400 is thinner with a lower freezing point. Choose by the solvency and flow the dosage form needs.

Where is polyethylene glycol 600 pharmaceutical grade used?

As a solvent for soft capsule fills, a co-solvent in oral liquids and drops, a component of ointment and suppository bases, and a plasticiser in tablet coatings. Dosage is set in formulation studies.

Which pharmacopoeia does polyethylene glycol 600 pharmaceutical grade follow?

Pharmaceutical grades are controlled under the polyethylene glycol monographs of ChP, USP or Ph. Eur., with key tests for average molecular weight, hydroxyl value, ethylene glycol and diethylene glycol, ethylene oxide and dioxane. The applicable standard is stated in the datasheet.

What if the product turns cloudy or solid in cold weather?

The freezing point of PEG 600 sits near room temperature, so hazing or going semi-solid in the cold is a physical change; warming under the conditions in the datasheet and stirring restores the appearance. Restored appearance is not a release decision — that follows your own quality procedure and the pharmacopoeial tests you work to. Keep sealed and avoid repeated freeze-thaw cycles.

How do I request a quote from SZMHTC?
