Description

Poly(vinyl acetate) USP

Poly(vinyl acetate) USP is a pharmacopeia-grade thermoplastic polymer used as a film-former, binder, and matrix-forming agent in controlled-release and chewable pharmaceutical formulations. Compliant with United States Pharmacopeia (USP) standards, this polymer is valued for its strong adhesive properties, mechanical resilience, and compatibility with a broad range of actives and excipients. Poly(vinyl acetate) USP is

• A USP-compliant excipient for sustained-release and chewable dosage forms
• A water-insoluble polymer with excellent adhesion and film-forming properties
• Commonly used in matrix tablets, coatings, and gums
• Suitable for aqueous dispersions and organic solvent systems
• Manufactured under Good Manufacturing Practice (GMP) certified conditions
• Supplied with complete regulatory documentation including Certificate of Analysis (CoA) and technical data

Poly(vinyl acetate) is a homopolymer of vinyl acetate that provides controlled diffusion of active ingredients in hydrophobic matrices. It is insoluble in water but disperses easily in aqueous systems and is soluble in alcohols and acetone. Its film-forming ability makes it especially effective in oral drug delivery applications requiring mechanical durability and prolonged drug release.

In pharmaceutical applications, Poly(vinyl acetate) USP is used in:

• Hydrophobic matrix tablets for extended-release oral drug delivery
• Film-coated tablets and multi-particulate systems for improved handling and stability
• Chewable tablets and medicated gums
• Barrier layers in multi-layer tablets to separate incompatible actives
• Adhesive components in oral and buccal films

The polymer is often blended with plasticizers and other excipients such as Poly(Vinyl Alcohol), Hydroxypropyl Methylcellulose, or Polyethylene Glycol to fine-tune flexibility, permeability, and release kinetics.

CarboMer supplies Poly(vinyl acetate) USP in a variety of particle sizes and viscosity grades. Custom formulations are available to meet application-specific needs for processing, release rate, or mechanical performance.

The material is packaged in sealed, moisture-resistant, tamper-evident containers. Available in research, clinical, and commercial volumes. Minimum order quantities (MOQ), lead times, and documentation—including CoA and SDS—are available upon request.

Each batch is tested for identity (IR), viscosity, residual monomers, loss on drying, microbial purity, and compliance with USP monograph specifications. All shipments include Certificates of Analysis (CoA), Safety Data Sheets (SDS), and full traceability documentation.

As with all CarboMer USP-grade excipients, Poly(vinyl acetate) USP is supported by technical guidance, regulatory compliance support, and a globally reliable supply chain to help bring your dosage forms to market efficiently and consistently.
