Description

Polyvinylcaprolactam CAS NO 25189-83-7 is a synthetic polymer derived from N-vinylcaprolactam, valued for its unique solubility and film-forming properties. This versatile polymer is crucial for formulators seeking to modify rheology, enhance stability, or create responsive materials in aqueous systems. It is particularly essential for manufacturers in the personal care, pharmaceutical, and specialty coatings industries.

Application

• Personal Care & Cosmetics: Used as a film-forming agent, hair fixative, and thickener in hair sprays, styling gels, and skin care products.
• Pharmaceuticals: Employed as a binder, coating agent, or matrix former in tablet formulations and controlled-release drug delivery systems.
• Industrial Coatings: Acts as a rheology modifier and dispersing aid in water-based paints, inks, and adhesives.
• Textile & Paper Processing: Serves as a sizing agent, coating additive, or processing aid to improve fiber strength and surface properties.
• Detergents & Cleaning Agents: Functions as an anti-redeposition agent and soil release polymer in laundry and dishwashing formulations.
• Agriculture: Utilized as an adjuvant in pesticide and herbicide formulations to improve spray retention and film formation on plant surfaces.

Quality Control

Our Polyvinylcaprolactam is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent molecular weight distribution, purity, and performance characteristics. A comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, residual monomer content, and viscosity is provided with every shipment to guarantee compliance with your specifications.

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); keep the container tightly sealed to prevent absorption of atmospheric moisture, which may affect product performance.
