Description

Carbomer Homopolymer Type B

CarboMer Homopolymer Type B is a high-purity, pharmaceutical-grade crosslinked Polyacrylic Acid polymer designed for use as a gelling agent, thickener, and controlled-release excipient in oral, topical, and mucosal formulations. It provides exceptional viscosity and bioadhesive properties, supporting stable, patient-friendly dosage forms across a range of pH environments. CarboMer Homopolymer Type B

• Is a pharmaceutical-grade crosslinked Polyacrylic Acid polymer
• Is used as a high-efficiency thickener, gel former, and bioadhesive matrix
• Is suitable for oral liquids, transdermal gels, ophthalmic formulations, and extended-release tablets
• Forms clear, stable gels upon neutralization with appropriate bases
• Is manufactured under Good Manufacturing Practice (GMP) certified conditions
• Is supplied with complete regulatory documentation including Certificate of Analysis (CoA) and supporting technical data

CarboMer Homopolymer Type B consists of high molecular weight acrylic acid crosslinked with Allyl Ethers of Pentaerythritol, producing a lightweight, white powder that rapidly hydrates and swells in water. Compared to Type A, Type B offers optimized rheological performance, providing higher viscosity in neutralized systems.

In pharmaceutical applications, CarboMer Homopolymer Type B is used in:

• Topical gels and creams for dermal, transdermal, or mucosal delivery
• Oral suspensions and syrups as a suspending agent and viscosity enhancer
• Ophthalmic gels and in-situ gelling vehicles to prolong ocular residence time
• Extended-release matrix tablets and multiparticulate systems
• Bioadhesive delivery platforms for improved mucosal contact and retention

CarboMer Homopolymer Type B efficiently thickens and stabilizes aqueous systems at concentrations as low as 0.2–1%. When neutralized with Sodium Hydroxide, Potassium Hydroxide, or Triethanolamine, it produces clear, smooth gels with excellent stability across pH ranges typically encountered in pharmaceutical formulations.

CarboMer supplies this excipient with rigorous control of microbial content, residual monomers, and heavy metals to ensure batch-to-batch consistency and regulatory compliance.

The material is packaged in sealed, moisture-controlled, tamper-evident containers. Available in laboratory, pilot, and commercial volumes. Minimum order quantities (MOQ), lead times, and full technical documentation are available upon request.

Each batch is tested for identification, viscosity, pH (in neutralized dispersion), residual solvents, microbial purity, and compliance with internal quality standards. Certificates of Analysis (CoA), Safety Data Sheets (SDS), and full traceability documentation are provided.

As with all CarboMer excipients, CarboMer Homopolymer Type B is supported by formulation expertise, regulatory guidance, and secure supply chain logistics to help you develop safe, effective, and patient-friendly therapies.
