This chemical is abbreviated as PEG 4000. The compound has the chemical formula H-(O-CH2-CH2)n-OH. This is a chemical made from Ethylene Oxide and water along with some other derivatives.

With its hydrophilic properties and some other characteristics, Polyethylene Glycol 4000 and its ions are quite commonly used in the market today to help produce detergents, cosmetics, medical applications…

Outstanding features of Polyethylene Glycol 4000 chemical
Characteristic properties:

• At 23oC, it is a clear, colorless liquid.
• Solidifies at 20oC.
• Resistant to strong acids and alkalis.
• Has a large molecular weight.
• Easily soluble in water.
• May react with household chemicals.

How to prepare and produce Polyethylene Glycol chemicals?
To create PEG 4000, people will react Ethylene Oxide with water (with added catalysts). With the chemical reaction equation as follows: HOCH2CH2OH + n(CH2CH2O) → HO(CH2CH2O)n + H

Applications of Polyethylene Glycol 4000
With the above outstanding features and properties, PEG 4000 has been widely applied in practice, in a variety of specific industries as follows:

Applications in agriculture
In agriculture, PEG 4000 plays a role as an ingredient in plant growth regulators and herbicides. It is an inert ingredient in pesticides and as a dust suppressant in some other agricultural chemicals.

Besides, according to research, the germination rate will be higher if the seeds are treated with PEG 4000 solution.

Used as a chemical intermediate
This chemical when combined with some other compounds helps increase the smoothness, moisture and adhesion of adhesives.
Used as a plasticizer to increase the durability of unfired ceramic products.
Used in some plastics and coatings to help increase dispersibility in water.

Polyethylene Glycol used as solvent
Cosmetic and personal care products when combined with PEG 4000 will help balance moisture, oiliness,… thanks to its properties of being easily soluble in water, non-volatile, non-irritating to the skin,…

Applications in some other fields such as: metal plating, production of plant growth stimulants, herbicides, in paper industry, lubricant production, synthetic plastic production…

Notes on safe use and storage of Polyethylene glycol chemicals
Notes on storage of PEG 4000
Store this chemical in a cool, dry place away from direct sunlight.
Chemical warehouses must be separated to avoid chemical leakage or spillage causing pollution.
Chemical warehouses must be located far from residential areas, away from water sources, places that store water for daily life or farming because it will seriously affect health.

What should be noted when using Polyethylene glycol?
When in contact with PEG 4000 chemicals in particular and other chemicals in general, you need to equip yourself with appropriate tools and full protective equipment.
