Description

Cellulose, 2-Hydroxypropyl Methyl Ether, Reaction Products With Glyoxal is a chemically modified cellulose derivative, specifically a glyoxal-crosslinked hydroxypropyl methylcellulose (HPMC). This product matters for its ability to form water-resistant films and coatings, enhancing the performance of water-soluble polymers. Industries requiring controlled release, improved adhesion, or moisture barrier properties will find this material essential. It is a key functional additive for formulators seeking to modify rheology and physical film characteristics.

Application

• Pharmaceutical Tablet Coating: As a film-forming agent to create enteric or sustained-release coatings that are resistant to gastric fluids.
• Construction Chemicals: As a thickener and water-retention agent in tile adhesives, grouts, and cement-based renders where improved workability and reduced water absorption are needed.
• Personal Care & Cosmetics: In hair styling gels, creams, and lotions to provide water-resistant film formation and enhanced hold.
• Food Packaging Coatings: As a component of biodegradable or edible coatings to provide a moisture barrier for food products.
• Textile Printing & Sizing: To improve the sharpness of prints and provide a temporary, water-resistant sizing that is easily removed.
• Industrial Adhesives: As a modifier in water-based adhesive formulations to enhance moisture resistance and bonding strength.

Quality Control

Our Cellulose, 2-Hydroxypropyl Methyl Ether, Reaction Products With Glyoxal is manufactured under a strict quality management system. Each batch is tested to ensure consistent performance in key parameters such as degree of substitution, crosslinking density, viscosity, and solubility profile. Certificates of Analysis (COA) documenting these specifications are available upon request. Production can be aligned with cGMP guidelines for 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 material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect flow properties and performance.
