Description

Actigel CAS NO 98443-65-3 is a high-purity, cross-linked polyvinylpyrrolidone (PVPP) polymer widely recognized as a superior clarifying and stabilizing agent. Its primary value lies in its ability to selectively adsorb polyphenols, tannins, and other haze-forming compounds, ensuring product clarity and shelf-life stability. This makes it an essential processing aid for manufacturers in the beverage, pharmaceutical, and nutraceutical industries seeking to improve the visual appeal and quality consistency of their final products.

Application

• Beverage Clarification: Primary use for the removal of polyphenols and tannins to prevent haze formation in beers, wines, ciders, and fruit juices.
• Pharmaceutical Purification: Used as an adsorbent in the purification processes of active pharmaceutical ingredients (APIs) and herbal extracts to remove unwanted phenolic compounds.
• Dietary Supplement Stabilization: Employed in liquid and semi-solid nutraceutical formulations to enhance clarity and chemical stability.
• Food Processing: Applied in the refining of edible oils, syrups, and vinegar to adsorb color bodies and impurities.
• Diagnostic Reagents: Serves as a stabilizer and adsorbent in the formulation of various clinical and laboratory diagnostic kits.
• Cosmetic Formulations: Used to stabilize and clarify lotions, toners, and other personal care products.

Quality Control

Our Actigel is manufactured under a strict quality management system. Each batch is tested to ensure it meets stringent specifications for adsorption capacity, particle size distribution, and residual monomer content. Certificates of Analysis (COA) documenting purity, physicochemical properties, and compliance with relevant food-grade or pharmaceutical standards (where applicable) are available upon request.

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). Keep away from strong oxidizing agents. The product is hygroscopic; ensure the container is sealed after each use to minimize moisture absorption.
