Description

Poly(acrylic acid)

Poly(acrylic acid) is a high-purity, pharmaceutical-grade synthetic polymer widely used as a thickener, stabilizer, suspending agent, and controlled-release matrix in pharmaceutical, biomedical, and personal care formulations. Its high molecular weight and strong anionic charge enable excellent viscosity control, mucoadhesive performance, and sustained-release capabilities across a broad range of delivery systems.

• It is a high-purity polyacrylic acid (PAA) polymer
• It has excellent thickening, suspending, and controlled-release properties
• It provides mucoadhesion and prolonged residence time in mucosal applications
• It is compatible with topical, ophthalmic, oral, mucosal, and transdermal formulations

Poly(acrylic acid) functions through hydrogen bonding, electrostatic interactions, and high molecular weight polymer entanglement, creating viscous gels that stabilize emulsions, suspensions, and active pharmaceutical ingredients (APIs). Its hydrophilic properties allow rapid hydration in aqueous media while maintaining long-term viscosity stability.

In oral dosage forms, Poly(acrylic acid) is widely used in matrix-based sustained-release tablets, suspensions, and controlled-release drug delivery platforms. In ophthalmic, nasal, and buccal formulations, it acts as a mucoadhesive polymer that increases residence time and improves drug absorption. In topical and transdermal products, it delivers smooth, uniform gels that enhance application consistency while stabilizing actives.

Pharmaceutical formulators, biomedical device manufacturers, and procurement professionals seeking to purchase Poly(acrylic acid) benefit from CarboMer ’s strict production standards, consistent material quality, and comprehensive regulatory support for global submissions and approvals.

The product is packaged in tamper-evident containers to maintain material integrity throughout storage and transportation. Minimum order quantities (MOQ), lead times, and complete regulatory support files are available upon request to support both early development and commercial-scale manufacturing.

Each batch of Poly(acrylic acid) undergoes validated analytical testing for molecular weight distribution and other specifications to ensure full compliance with regulatory expectations and batch-to-batch reproducibility.

As with all CarboMer excipients and controlled-release polymers, Poly(acrylic acid) 8-04922 is supported by expert formulation consultation, regulatory assistance, and  technical support to help clients advance development programs efficiently and with full regulatory confidence.
