Description

Poly(ethylene glycol)

Poly(ethylene glycol) (PEG) is a high-purity, nonionic, water-soluble polymer widely used across pharmaceutical, biotechnology, and biomedical applications for its exceptional solubilizing, stabilizing, and delivery-enhancing properties. Its versatile molecular weight range, excellent safety profile, and regulatory acceptance make PEG an essential excipient and carrier in regulated drug delivery systems, biologics, and implantable devices. PEG

• Is a pharmaceutical-grade, water-soluble nonionic polymer
• Is available in a broad molecular weight range for diverse applications
• Functions as solubilizer, stabilizer, plasticizer, and delivery carrier
• Is fully biocompatible and highly safe across multiple dosage forms

Poly(ethylene glycol) consists of repeating ethylene oxide units, yielding a neutral, highly hydrophilic polymer that dissolves readily in both water and many organic solvents. PEG’s tunable molecular weight distribution allows its application across a wide range of formulation types, from low molecular weight PEGs (e.g., PEG 400) used as solvents and plasticizers, to high molecular weight PEGs (e.g., PEG 3350, PEG 8000) functioning as osmotic agents, excipients, and formulation stabilizers.

In pharmaceutical drug products Poly(ethylene glycol) is widely used as a solvent, wetting agent, suspending agent, plasticizer, and bioavailability enhancer for poorly soluble active pharmaceutical ingredients (APIs). In parenteral, ophthalmic, topical, and oral dosage forms, PEG improves solubility, stability, and drug absorption profiles.

PEG’s unique chemical properties also make it a foundational material for advanced biologic delivery technologies, such as PEGylation of proteins, peptides, and nucleic acids, which extends half-life, reduces immunogenicity, and improves therapeutic efficacy. In drug-device combination products, PEG supports hydrogel formation, tissue scaffolds, and controlled-release implantables.

Pharmaceutical developers and procurement teams seeking to purchase Poly(ethylene glycol) benefit from CarboMer’s rigorous manufacturing consistency, validated quality control processes, and comprehensive regulatory documentation to support global clinical and commercial applications.

The material is supplied in tamper-evident, moisture-controlled containers to ensure long-term storage stability. Minimum order quantities (MOQ), lead times, and full regulatory support files are available for development through commercialization.

Each batch undergoes validated testing for molecular weight, viscosity, hydroxyl value, residual ethylene oxide and dioxane, heavy metals and microbial purity to meet pharmacopeial (USP/NF, Ph. Eur.) standards and ensure full regulatory compliance.

As with all CarboMer excipients, Poly(ethylene glycol) is fully supported by technical consultation, formulation development guidance, and regulatory assistance to enable efficient product development, global filings, and lifecycle management.
