Description

Vinol 523 is a high-purity, synthetic polymer widely recognized for its versatile performance as a film-forming agent and binder. Its consistent quality and reliable performance make it a critical component for formulators requiring precise rheological control and adhesion. This product is essential for manufacturers in the pharmaceutical, personal care, and specialty coatings industries seeking to enhance product stability and functionality.

Application

• As a primary film-forming agent in pharmaceutical tablet coatings and controlled-release formulations.
• As a binder and stabilizer in cosmetic and personal care products, including hair styling gels and skin creams.
• In the formulation of specialty adhesives and sealants requiring high tack and flexibility.
• As a protective colloid and thickening agent in aqueous industrial coatings and inks.
• For the microencapsulation of active ingredients in agrochemicals and nutraceuticals.
• In the production of water-soluble films for unit-dose packaging (e.g., detergent pods).

Quality Control

Our Vinol 523 is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure it meets precise specifications for viscosity, degree of hydrolysis, and residual monomer content. Certificates of Analysis (COA) documenting compliance with relevant standards, including USP/NF where applicable, are provided to guarantee supply reliability and batch-to-batch consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after initial use to prevent moisture absorption and caking.
