Description

Polyvinylpyrrolidone-o-Phenylphenol is a polymeric complex formed from polyvinylpyrrolidone (PVP) and o-phenylphenol, designed to enhance the stability and efficacy of the active phenolic component. This compound is valued for its controlled-release properties and broad-spectrum antimicrobial activity, making it a critical ingredient in formulations requiring sustained action. It is primarily utilized by manufacturers in the pharmaceutical, personal care, and industrial biocides sectors seeking advanced stabilization and delivery solutions.

Application

• Pharmaceutical Preservative & Disinfectant: Used in topical antiseptic creams, ointments, and disinfectant solutions for its prolonged antimicrobial efficacy.
• Cosmetic & Personal Care Formulations: Serves as a stabilized preservative in lotions, creams, and deodorants to prevent microbial growth.
• Industrial Biocides and Fungicides: Incorporated into coatings, adhesives, and polymer emulsions to provide long-lasting protection against mold and bacteria.
• Veterinary Products: Applied in disinfectant and wound care formulations for animal health.
• Agricultural Adjuvants: Used in pesticide formulations to enhance the stability and delivery of active ingredients.
• Material Protection: Applied to textiles, leather, and other materials to impart antimicrobial properties.

Quality Control

Our Polyvinylpyrrolidone-o-Phenylphenol is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent composition, purity, and performance. While specific grades can be produced, our standard quality control includes verification of complex formation, assay of active phenolic content, and residual solvent analysis. Certificates of Analysis (COA) documenting compliance with agreed specifications are provided with every shipment.

Storage

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