Description

Glyoxal-Methyl Hydroxyethyl Cellulose Copolymer is a chemically modified cellulose ether designed for superior performance in aqueous systems. This specialized copolymer is engineered to provide enhanced rheological control, water retention, and film-forming properties compared to standard cellulose derivatives. It serves as a critical functional additive for formulators in the paints & coatings, construction chemicals, personal care, and pharmaceutical industries, where precise viscosity modification and stability are paramount.

Application

• Paints & Coatings: Acts as a highly efficient thickener, rheology modifier, and water retention agent in water-based architectural paints, industrial coatings, and texture finishes.
• Construction Chemicals: Used in cement-based tile adhesives, grouts, self-leveling compounds, and plaster to improve workability, sag resistance, and open time.
• Personal Care & Cosmetics: Functions as a film former, thickener, and stabilizer in hair styling gels, creams, lotions, and sunscreen formulations.
• Pharmaceuticals: Employed as a binder, sustained-release matrix former, and coating agent in tablet formulations.
• Adhesives & Sealants: Provides viscosity control and enhances the application properties of water-based adhesive systems.
• Textile Printing: Serves as a thickener for pigment printing pastes, offering excellent color yield and sharp print definition.

Quality Control

Our Glyoxal-Methyl Hydroxyethyl Cellulose Copolymer is manufactured under a stringent quality management system. Each batch is tested against rigorous in-house specifications to ensure consistent performance in viscosity, solubility, and chemical stability. Certificates of Analysis (COA) documenting key parameters such as assay, viscosity, moisture content, and particle size distribution are available upon request. We adhere to cGMP principles where applicable to support demanding industrial and pharmaceutical applications.

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 when not in use to prevent moisture absorption, which can affect flow properties and performance.
