Description

Poly(ethylene glycol) Alginate

Poly(ethylene glycol) Alginate (PEG Alginate) is a high-purity, water-soluble, amphiphilic biopolymer designed for advanced drug delivery, biomedical engineering, and controlled-release applications. By combining the mucoadhesive, gel-forming properties of alginate with the hydrophilicity and biocompatibility of poly(ethylene glycol) (PEG), this multifunctional excipient supports stable drug encapsulation, improved bioavailability, and tailored release kinetics.

• It is a pharmaceutical-grade, amphiphilic PEG-modified alginate polymer
• It  forms stable hydrogels, encapsulation matrices, and bioadhesive delivery systems
• It supports oral, mucosal, parenteral, and implantable formulations
• It enhances solubility, stability, and controlled drug release profiles
• It is fully biocompatible, hydrogel-forming, and bioresorbable

Poly(ethylene glycol) Alginate is produced through controlled PEGylation of alginate’s carboxylate groups, improving its solubility, flexibility, and crosslinking capability while preserving its ion-responsive gelation behavior. The polymer can form physically or chemically crosslinked hydrogels, allowing formulators to create customized drug delivery platforms with precise control over release profiles and gel strength.

In drug delivery, PEG Alginate is used to develop oral sustained-release formulations, mucoadhesive buccal films, injectable depots, and bioresponsive hydrogels that stabilize sensitive proteins, peptides, or small-molecule actives. The PEG component enhances water solubility, reduces protein adsorption, and prolongs systemic circulation for injectable delivery systems.

In regenerative medicine and biomedical applications, Poly(ethylene glycol) Alginate supports cell encapsulation, wound healing matrices, tissue scaffolds, and drug-eluting implants where tunable gelation, biocompatibility, and mechanical properties are essential for tissue integration and healing.

Developers and procurement professionals seeking to purchase Poly(ethylene glycol) Alginate benefit from CarboMer’s validated manufacturing processes, consistent batch reproducibility, and global regulatory support to facilitate efficient development and worldwide registration.

Material is supplied in moisture-controlled, tamper-evident packaging to maintain long-term stability during storage and transportation. Minimum order quantities (MOQ), lead times, and complete technical files are available for early development, clinical trials, and commercial manufacturing.

Each batch undergoes validated analytical testing for PEG content, molecular weight distribution, degree of substitution, viscosity, heavy metals, and microbial safety, ensuring regulatory compliance and global acceptance.

As with all CarboMer biomaterials and excipients, Poly(ethylene glycol) Alginate is fully supported by formulation consultation, technical development services, and regulatory guidance to help clients advance product development through every stage of the commercialization lifecycle.
