Product Description

Source:Polyethylene Glycol (PEG) is a polymer formed by the gradual addition polymerisation of ethylene oxide with water or ethylene glycol. Depending on the molecular weight, PEG can assume a variety of physical forms ranging from a colourless, odourless liquid to a waxy solid. Below are some introductory points about polyethylene glycol products:
Molecular weight and physical state:
Low molecular weight PEGs (e.g. PEG 200, PEG 400) are usually clear liquids.
Medium molecular weight PEGs (e.g. PEG 1500, PEG 3350) are semi-solid or soft waxy.
Application Areas:
Pharmaceutical industry: as drug carrier, ointment matrix, suppository matrix, etc., used to improve the solubility and stability of drugs.
Cosmetics: used as humectant, thickener and emulsifier.
Industrial applications: as lubricants, dispersants, plasticisers and antistatic agents.
Biotechnology: used in experiments such as protein crystallisation, cell fusion and DNA transformation.
Safety:
PEG is generally considered safe, but may cause allergic reactions or irritation in some cases.
III. Characteristics and Classification
According to the molecular weight, PEG can be divided into the following categories:
Low molecular weight PEG:
The molecular weight range is usually between 200 and 600.It is liquid with good solubility and flowability.Applications: solvents for drugs, moisturisers in cosmetics, etc.
Medium molecular weight PEG:Molecular weight range is approximately between 1000 and 4000.Semi-solid or soft wax-like.
Applications: ointment bases, suppository bases, industrial lubricants, etc.High Molecular Weight PEG:Molecular weight range of 6,000 to 20,000 or higher.
Solid, usually in powder or granules.
Applications: controlled drug release systems, thickeners, dispersants, etc.Ultra High Molecular Weight PEG:Molecular weight over 20,000.Has higher viscosity and film forming properties.Applications: special pharmaceutical uses, advanced cosmetics, etc.
