Chemicals - Polyethylene glycol (PEG)

General Description

Polyethylene glycol (PEG) is a versatile, water-soluble polymer that belongs to the class of polyether compounds. It is formed by the polymerization of ethylene oxide, resulting in a chain of repeating ethylene glycol units. PEG is available in various molecular weights, with each weight corresponding to a different average number of ethylene glycol units in the chain.

PEG is a clear, odorless, and viscous liquid or solid, depending on its molecular weight.


1. Pharmaceuticals:

PEG is extensively used in the pharmaceutical industry. It serves as a solubilizing agent, improving the solubility of poorly soluble drugs. PEG is also used as a base or vehicle for various dosage forms such as creams, ointments, suppositories, and oral liquids. It can enhance drug absorption, stability, and bioavailability.

2. Personal Care Products:

PEG is utilized in a variety of personal care products, including cosmetics, skincare items, hair care products, and toothpaste. It acts as a moisturizer, emulsifier, and thickening agent. PEG helps to improve the texture, spread ability, and stability of these products.

3. Industrial Applications:

PEG finds application in various industrial processes. It is used as a lubricant, antistatic agent, and plasticizer. PEG is also employed as a dispersant and emulsion stabilizer in paints, coatings, and adhesives.

4. Food and Beverages:

PEG is approved for use in food and beverages as a food additive. It is employed as a thickening agent, stabilizer, and humectant. PEG can enhance the texture, mouthfeel, and shelf life of products such as ice cream, candies, baked goods, and beverages.

5. Agriculture:

PEG is utilized in agriculture for seed coating, as it can improve seed germination and moisture retention. It is also employed as a carrier for pesticides, herbicides, and fertilizers.
