Description

Ethyl Ester Of Pvm/Ma Copolymer is a synthetic polymer derived from the copolymerization of vinyl methyl ether and maleic anhydride, subsequently esterified with ethanol. This chemical is valued for its excellent film-forming, adhesive, and binding properties, making it a versatile functional ingredient. It is primarily sought after by manufacturers in the personal care, pharmaceutical, and industrial coating sectors for its ability to modify rheology and enhance product performance.

Application

• Hair Styling Products: Acts 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 & Cosmetics: Used as a binder and stabilizer in creams, lotions, and sunscreens, contributing to a smooth texture and improved product spreadability.
• Pharmaceutical Coatings: Serves as an enteric or controlled-release coating agent for tablets and capsules, protecting active ingredients from gastric acid.
• Adhesives and Sealants: Functions as a tackifier and rheology modifier in pressure-sensitive and water-based adhesive formulations.
• Industrial Coatings: Imparts gloss, hardness, and water resistance in specialty paints, inks, and overprint varnishes.
• Oral Care Products: Utilized as a film-forming polymer in mouthwashes and dental strips to aid in the delivery and retention of active ingredients.

Quality Control

Our Ethyl Ester Of Pvm/Ma Copolymer is manufactured under a strict quality management system. Each batch is tested to ensure it meets stringent specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, residual solvents, and viscosity are available upon request. We can support compliance with relevant frameworks including ISO, GMP, and REACH for our global clientele.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
