Description

Vp/Eicosene Copolymer CAS NO 28211-18-9 is a synthetic polymer derived from the copolymerization of vinylpyrrolidone (VP) and eicosene. This versatile material is valued for its ability to modify rheology, enhance film formation, and provide conditioning properties across diverse industrial formulations. It is a critical component for manufacturers in the personal care, coatings, adhesives, and specialty chemical sectors seeking to improve product performance and stability.

Application

• Hair Care Products: Acts as a film-forming agent and conditioner in shampoos, conditioners, and styling products to provide hold, shine, and manageability.
• Skin Care & Cosmetics: Used in creams, lotions, and makeup formulations for its emulsifying and stabilizing properties, improving texture and long-wear characteristics.
• Industrial Coatings & Inks: Functions as a rheology modifier and dispersant to control viscosity, enhance pigment suspension, and improve application properties.
• Adhesives & Sealants: Imparts tackifying and binding properties, improving adhesion and cohesion in pressure-sensitive and structural adhesive systems.
• Textile & Fiber Treatment: Serves as a sizing agent and softener, improving fiber processing, hand feel, and durability of fabrics.
• Pharmaceutical & Nutraceutical Coatings: Utilized in tablet film coating and encapsulation to control drug release and mask unpleasant tastes.

Quality Control

Our Vp/Eicosene Copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in molecular weight distribution, viscosity, and residual monomer content, meeting the high standards required for personal care and industrial applications. Certificates of Analysis (COA) are available upon request to support your quality assurance and regulatory compliance needs.

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); ensure containers are sealed tightly after each use to prevent moisture absorption, which may affect product performance.
