Description

Hydroxybutylcellulose is a water-soluble, non-ionic cellulose ether derivative, valued for its unique thickening, stabilizing, and film-forming properties. This versatile polymer is essential for formulators seeking to control rheology and enhance product performance in aqueous systems. Key industries that rely on this material include pharmaceuticals, personal care, and specialty coatings, where consistent quality and reliable functionality are paramount.

Application

• Pharmaceutical Formulations: Used as a binder, sustained-release matrix former, and viscosity modifier in tablet coatings and topical gels.
• Personal Care Products: Acts as a thickener and stabilizer in shampoos, lotions, and creams to improve texture and shelf-life.
• Specialty Coatings: Employed as a film-former and rheology control agent in water-based paints and industrial coatings.
• Adhesives and Sealants: Functions as a thickener and water-retention agent to improve application properties and bond strength.
• Ceramic Processing: Serves as a binder and plasticizer in ceramic slips and pastes to enhance green strength and shaping.
• Textile Printing: Utilized as a thickener in pigment printing pastes to achieve sharp print definition and color yield.

Quality Control

Our Hydroxybutylcellulose is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for viscosity, degree of substitution, purity, and moisture content. Certificates of Analysis (COA) documenting these results are provided and available upon request to support your quality assurance protocols.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product performance.
