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.
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.
