Description

Carbomer Homopolymer Type A

CarboMer Homopolymer Type A is a high-purity, pharmaceutical-grade crosslinked Polyacrylic Acid polymer used as a thickening agent, gelling agent, and controlled-release excipient in oral, topical, and mucosal formulations. It provides efficient viscosity enhancement and bioadhesive properties even at low concentrations, supporting a wide range of dosage forms. CarboMer Homopolymer Type A

• Is a pharmaceutical-grade crosslinked Polyacrylic acid polymer
• Provides efficient thickening, suspending, and controlled-release capabilities
• Is suitable for oral liquids, topical gels, creams, and extended-release matrices
• Is neutralizable with bases to form clear, stable gels
• 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 A is composed of high molecular weight acrylic acid crosslinked with allyl ethers of pentaerythritol. This structure yields a white, fluffy powder that swells in water to form highly viscous colloidal dispersions or gels.

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

• Topical gels and creams for dermal or mucosal drug delivery
• Oral suspensions and syrups as a suspending and stabilizing agent
• Controlled-release tablet matrices to modulate dissolution profiles
• Bioadhesive formulations to enhance mucosal retention and prolong contact time
• Ophthalmic gels and in-situ gelling systems

The polymer is highly efficient, achieving desired viscosities at concentrations as low as 0.2–1%. Upon neutralization with suitable bases (e.g., Sodium Hydroxide, Triethanolamine), it forms clear, stable gels compatible with a broad pH range.

CarboMer supplies CarboMer Homopolymer Type A with rigorous controls on residual solvents, microbial load, and heavy metals. The material conforms to applicable compendial specifications and is fully traceable for regulated pharmaceutical use.

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

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

As with all CarboMer excipients, CarboMer Homopolymer Type A is supported by technical formulation assistance, regulatory consulting, and dependable supply to help you bring stable, effective, and patient-friendly dosage forms to market.
