INTRODUCTION
Polyethylene glycols (PEG), also known as macrogols, are liquid or solid polymers of the general formula H(OCH2CH2)n OH, where n is greater or equal to four.
MANUFACTURE
PEG’s are produced by the interaction of ethylene oxide with water, ethylene glycol or ethylene glycol oligomers. The reaction is catalyzed by acidic or basic catalysts
| Synonym | Poly(oxyethylene), Poly(ethylene oxide) ; Poly(oxy-1,2-ethanediyl), α-hydro-ω-hydroxy- |
| CAS no. | 25322-68-3 |
| EINECS no. | 500-038-2 |
| Molecular formula | H(OCH2CH2)nOH |
| Molecular weight | 200 to several million |
| Structure |  |
APPLICATIONS
The outstanding features of the PEGs include their wide compatibility across a range of solvents, wide viscosity range, and hygroscopicity. They are odorless, colorless and show excellent lubricity with low or no toxicity and low volatility.
PEG’s find an increasing use in the Pharma and Personal Care industries:

L-carnitine Hydrochloride is a water soluble, stable salt form of L- Carnitine. It is a naturally occurring amino acid derivative. It is often used as a dietary supplement due to its role in energy production and fat metabolism.
Dimenhydrinate is an antihistamine drug commonly used to prevent and treat motion sickness, nausea, and vertigo. It is a combination of diphenhydramine and 8-chlorotheophylline, where the latter reduces the sedative effects of diphenhydramine. It is available in tablet, liquid, and injectable forms under various brand names.
o-Nitrophenyl Disulfide is a chemical compound used in organic chemistry and biochemistry. It is a disulfide derivative where two o-nitrophenyl groups are connected by a disulfide bond (-S-S-) It is used in various organic synthesis reactions, as a reagent in the preparation of thiol-reactive compounds, in pharmaceutical research and laboratory applications.
Tetrasodium pyrophosphate (TSPP) anhydrous is a white, crystalline or granular inorganic compound, soluble in water but insoluble in alcohol. TSPP is widely used in food, industrial, and cleaning applications due to its sequestrant, dispersing, buffering, and emulsifying properties.
Potassium sodium tartrate commonly known as Rochelle salt, is a double salt of tartaric acid. It is a white crystalline solid that is highly soluble in water. This compound is well known for its piezoelectric properties and has been historically used in various scientific and industrial applications.
Tert-Amyl Alcohol (TAA) also known as 2-Methyl-2-butanol, is a branched-chain alcohol. It is a colorless, flammable liquid with a mild alcoholic odor and moderate water solubility. Due to its unique structural properties, it is widely used as basic organic chemical in synthetic fragrances, pharmaceuticals and pigment industries.
Lithium orotate is a compound consisting of lithium, an alkali metal, and orotic acid, a natural substance involved in nucleic acid metabolism. It is a popular dietary supplement due to its potential neuroprotective and mood-stabilizing effects.
Quinuclidinone Hydrochloride is a derivative of bicyclic amine quinuclidine. The hydrochloride form of quinuclidinone is the salt form, often used for its stability in different reactions. Quinuclidinone Hydrochloride is typically used as an intermediate in the synthesis of various pharmaceuticals and other chemical products.
Potassium benzoate (E212), the potassium salt of benzoic acid, is a food preservative used to prevent the growth of mold, yeast and some bacteria. It works best in low-pH products, below 4.5, where it exists as benzoic acid.
