Description

Poly(vinyl alcohol) USP

Poly(vinyl alcohol) USP is a high-purity, water-soluble synthetic polymer used in pharmaceutical and medical applications for its film-forming, adhesive, and stabilizing properties. Compliant with United States Pharmacopeia (USP) standards, it is widely used in oral solid dosage forms, ophthalmic products, wound care systems, and controlled-release drug delivery matrices. Poly(vinyl alcohol) (PVA) is

• A USP-compliant water-soluble polymer for regulated pharmaceutical use
• Excellent film-forming, emulsifying, and has excellent binding performance
• Used in tablets, capsules, ophthalmic gels, and wound dressings
• Biocompatible, non-toxic, and suitable for mucosal and parenteral formulations
• Manufactured under Good Manufacturing Practice (GMP) certified conditions
• Supplied with complete regulatory documentation including Certificate of Analysis (CoA) and technical data

Poly(vinyl alcohol) is synthesized through the hydrolysis of Poly(vinyl acetate), with properties that depend on the degree of hydrolysis and molecular weight. It forms clear, strong, flexible films and viscous aqueous solutions that can be used for sustained release and bioadhesive effects.

In pharmaceutical and biomedical applications, Poly(vinyl alcohol) USP is used in:

• Tablet binders and film coatings for improved mechanical stability and appearance
• Matrix systems for extended-release oral dosage forms
• Ophthalmic products including artificial tears and in situ gelling eye drops
• Transdermal systems, wound dressings, and hydrogel patches
• Medical adhesives and mucoadhesive films for buccal and vaginal delivery

Its high water solubility and safety profile make poly(vinyl alcohol) ideal for sensitive applications where low toxicity, high clarity, and thermal stability are required. It is also compatible with a variety of actives and excipients.

CarboMer supplies Poly(vinyl alcohol) USP in multiple grades based on viscosity and hydrolysis level, allowing precise control over gel strength, dissolution rate, and mechanical behavior. Custom blends are available on request.

The material is packaged in sealed, moisture-controlled, tamper-evident containers. Available in R&D, clinical, and commercial volumes. Minimum order quantities (MOQ), lead times, and documentation including CoA and SDS are provided upon request.

Each batch is tested for identity (IR, NMR), viscosity, degree of hydrolysis, loss on drying, pH, 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 alcohol) USP is supported by technical consultation, regulatory assistance, and dependable global logistics to ensure consistent product development and compliance across oral, topical, and injectable systems.
