Polyvinyl Alcohol (PVA) – High-Quality Film Coating and Ophthalmic Excipient from China
1. General Introduction to Polyvinyl Alcohol (PVA)
Polyvinyl Alcohol (PVA) is a water-soluble synthetic polymer, prominent for its excellent film-forming ability, high adhesive properties, chemical stability, and exceptional biosafety. This active ingredient is widely used as a multi-functional excipient in pharmaceutical formulations (especially in film coatings and binders) and in healthcare and medical products (such as eye drops and artificial tears).
The raw material is manufactured by Jiangxi Alpha Hi-Tech Pharmaceutical Co., Ltd. (China), one of the most reputable specialized excipient and chemical manufacturers. With advanced synthesis and purification processes, Polyvinyl Alcohol from Jiangxi Alpha achieves optimal purity, strictly controlling impurity indices, ensuring absolute consistency across production batches, and fully complying with the most rigorous global pharmacopoeial standards.
2. Polyvinyl Alcohol (PVA) Raw Material Information
Functions: Film coating excipient, tablet binder, thickening agent, viscosity enhancer in ophthalmic solutions.
Chemical Composition: Synthetic polymer with the general formula $(C_2H_4O)_n$.
Physical Form: White to pale cream crystalline powder or fine granules, odorless or with a faint characteristic odor.
Solubility: Highly soluble in water (depending on the degree of hydrolysis, it may dissolve at room temperature or require heating), practically insoluble in organic solvents.
Quality Standards: Complies with the United States Pharmacopeia (USP), European Pharmacopoeia (EP), or Chinese Pharmacopoeia (ChP).
The raw material is strictly controlled for:
Residual Solvent Limits: Strict control of residual solvents during the synthesis process, ensuring absolute safety for oral and mucosal administration.
Degree of Hydrolysis and Molecular Weight: Ensures precise technical specifications to maintain stable viscosity and the ability to form tough, glossy films.
Heavy Metal and Microbial Indices: Meets stringent microbiological standards for oral preparations and eye drops.
3. Key advantages of Polyvinyl Alcohol
Superior Film-Forming and Adhesive Properties: Creates a transparent, tough, and beautifully glossy film coating, helping to optimally protect the active ingredients inside the tablet from moisture, light, and oxidation.
High Biosafety: Jiangxi Alpha's impurity control process is extremely rigorous, resulting in high purity, non-toxicity, and excellent biocompatibility (safe for direct use on the ocular mucosa).
Flexible Formulation Properties: High mechanical durability, good stability, and compatible with most common active pharmaceutical ingredients. PVA can be easily combined with other plasticizers to adjust the elasticity of the coating film.
Reasonable Cost & Stable Supply: Manufactured in China by Jiangxi Alpha Hi-Tech, the product offers a highly competitive price, providing an effective solution for manufacturing plants to optimize production costs while maintaining foreign-standard quality.
4. Applications of Polyvinyl Alcohol (PVA)
In Pharmaceuticals (Core Applications)
Film Coating Systems: Acts as a core component (film-former) for tablet and capsule film coating formulations, helping to mask unpleasant tastes/odors and improve the tablet's appearance.
Binders: Used as a binder in wet granulation processes, improving hardness and preventing tablet friability.
Ophthalmic Solutions: Applied as a lubricant and viscosity enhancer in eye drops and artificial tears to retain moisture and reduce dry eyes and irritation.
Hydrogels and Topical Medications: Used as a base matrix for transdermal patches or medical gels.
In Cosmetics
Skincare Products: Widely used in peel-off masks due to its adhesive film-forming and easy-peeling capabilities
