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.
