FAQ’S
What is Polyethylene glycol?
Polyethylene glycol (PEG), a water-soluble polymer, is commonly used as a laxative and in various other applications, including drug delivery and biomedical applications.
What are the uses of Polyethylene glycol?
Polyethylene glycol is a common form used to treat constipation, working by increasing water absorption in the intestines, softening stool, and prompting bowel movements.
Polyethylene glycol can be used to coat nanoparticles or as linkers for antibody-drug conjugates (ADCs) to improve drug delivery. It is used as a carrier solvent and excipient in food industry.
What are the health risks of Polyethylene glycol?
The health risks of Polyethylene glycol are bloating, gas, and diarrhea are common side effects when used medically.
Choice Organochem LLP supplies Polyethylene glycol to users/customers for Personal care & Pharmaceuticals and Food & Beverages.
Polyethylene glycol Specifications
Food Grade-JECFA
| Test Items | Specifications |
| Appearance | PEG’s below 700 molecular weight occur as clear to slightly hazy, colourless, slightly hygroscopic liquids with a slight characteristic odour. PEG’s between 700-900 are semi-solid. PEG’s over 1000 molecular weight are creamy white waxy solids, flakes, or free-flowing powders. |
| Solubility | Polyethylene glycols having a molecular weight of 1000 or above are freely soluble in water; polyethylene glycols are soluble in many organic solvents, including aliphatic ketones and alcohols, chloroform, glycol ethers, esters, and aromatic hydrocarbons; they are insoluble in ether and in most aliphatic hydrocarbons; with increased molecular weight, water solubility and solubility in organic solvents decreases |
