Description

Isopropyl Ester Of Pvm/Ma Copolymer CAS NO 54578-88-0 is a specialized film-forming polymer derived from the copolymerization of methyl vinyl ether and maleic anhydride, subsequently esterified with isopropanol. This chemical is engineered to deliver exceptional binding, thickening, and film-forming properties in a variety of demanding formulations. It is a critical raw material for manufacturers in the personal care, pharmaceutical, and industrial coating sectors seeking to enhance product performance and stability.

Application

• Hair Styling Products: Serves as a primary film-forming agent and fixative in hair sprays, gels, and mousses, providing strong hold with good flexibility and humidity resistance.
• Skin Care & Color Cosmetics: Used as a binder and stabilizer in sunscreens, lotions, and makeup formulations to improve water resistance, texture, and long-wear properties.
• Pharmaceutical Coatings: Employed in the formulation of enteric or sustained-release tablet and capsule coatings, offering controlled solubility profiles.
• Industrial Adhesives: Acts as a key component in pressure-sensitive adhesives and specialty glues, contributing to tack and cohesive strength.
• Printing Inks: Functions as a rheology modifier and binder in ink formulations to control viscosity and improve adhesion to various substrates.
• Textile Finishing: Utilized in fabric coatings and finishes to impart stiffness, water repellency, or specific hand feel.

Quality Control

Our Isopropyl Ester Of Pvm/Ma Copolymer is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency in critical parameters such as esterification degree, viscosity, and residual solvents. We provide Certificates of Analysis (COA) with every shipment, detailing the specifications and test results. Our quality commitment aligns with cGMP principles where applicable, supporting its use in regulated markets.

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 each use to prevent moisture absorption, which can affect its performance. Keep away from incompatible materials such as strong bases.
