Pharmaceutical Grade Polyethylene Glycol

Pharmaceutical Grade Polyethylene Glycol (PEG) is a high-purity, water-soluble polymer widely used as a multifunctional excipient in modern pharmaceutical formulations. Manufactured under strict GMP conditions and refined to meet pharmacopeial standards, pharmaceutical PEG offers consistent molecular weight control, excellent safety, and reliable performance in medicinal applications.

Pharmaceutical grade PEG is commercially available in a wide range of controlled molecular weights, including PEG-200, PEG-300, PEG-400, PEG-600, PEG-1000, PEG-1500, PEG-2000, PEG-4000, PEG-6000, and PEG-8000. Lower molecular weight grades are clear, colorless liquids, while higher molecular weight PEGs are supplied as semi-solids, flakes, or free-flowing powders to suit different dosage forms. In pharmaceutical manufacturing, low molecular weight PEGs such as PEG-200 to PEG-400 are commonly used as solvents, plasticizers, humectants, and carriers in oral liquids, syrups, injectables, and topical formulations. Medium molecular weight PEGs including PEG-600 to PEG-2000 function as binders, dispersants, ointment bases, and emulsifying agents, improving formulation stability and drug uniformity.

High molecular weight PEGs such as PEG-4000 to PEG-8000 are widely used as tablet binders, capsule excipients, suppository bases, film-formers, and controlled-release matrices. Molecular weights typically range from 200 to over 8,000 g/mol, directly influencing viscosity, melting point, solubility, and drug release behavior.

Key properties of pharmaceutical grade polyethylene glycol include exceptional purity, chemical and thermal stability, low toxicity, neutral taste and odor, excellent water solubility, and high compatibility with active pharmaceutical ingredients. Supplied in pharma-approved packaging with full documentation, pharmaceutical grade PEG provides manufacturers with a reliable, compliant, and cost-effective excipient for producing high-quality, safe, and globally marketable medicines.

FAQ Pharmaceutical Grade Polyethylene Glycol

Pharmaceutical Grade Polyethylene Glycol is mainly used as a pharmaceutical excipient, solvent, binder, coating agent, suppository base, lubricant, and active ingredient carrier in various drug formulations.

The common commercial grades include PEG 200, PEG 300, PEG 400, PEG 600, PEG 1000, PEG 1500, PEG 3350, PEG 4000, PEG 6000, and PEG 8000, which are selected based on molecular weight and application requirements.

Low molecular weight PEG grades are mainly liquid and used as solvents and carriers, while high molecular weight PEG grades are solid and used for tablet binding, coatings, suppositories, and controlled-release pharmaceutical systems.

Pharmaceutical Grade PEG is manufactured through controlled polymerization of ethylene oxide followed by purification, filtration, drying, and strict quality control testing to achieve pharmaceutical standards.

PEG provides excellent water solubility, chemical stability, low toxicity, compatibility with active ingredients, moisture retention, and improved formulation performance.
