Description

Ethyl Cellulose is a versatile, non-toxic, and inert ethyl ether of cellulose, widely recognized for its excellent film-forming, binding, and hydrophobic properties. This high-performance polymer is crucial for formulating controlled-release drug delivery systems and creating durable, water-resistant coatings. It is an essential material for manufacturers in the pharmaceutical, food, nutraceutical, and specialty coatings industries seeking reliable functional excipients and additives.

Application

• Pharmaceutical Tableting & Encapsulation: Acts as a primary binder, filler, and controlled-release agent in solid oral dosage forms.
• Functional Food & Nutraceutical Coatings: Used for enteric and protective coatings on supplements and food ingredients to mask taste and control release.
• Specialty Paints & Coatings: Imparts toughness, flexibility, and water resistance in industrial, wood, and metal coatings.
• Printing Inks: Serves as a film-forming agent and rheology modifier for high-quality flexographic and gravure inks.
• Adhesives & Sealants: Provides binding strength and moisture resistance in hot-melt and specialty adhesive formulations.
• Personal Care Products: Functions as a thickener, film-former, and stabilizer in hair sprays, nail polish, and other cosmetic products.

Quality Control

Our Ethyl Cellulose is manufactured under strict quality management systems. We offer grades compliant with major pharmacopoeial standards, including USP-NF, Ph. Eur., and JP, as well as food-grade specifications (FCC). Each batch is tested for critical parameters such as ethoxyl content, viscosity, and residue on ignition to ensure consistent performance and purity. A comprehensive Certificate of Analysis (COA) is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, store in a cool, dry place at 15-25°C. Keep the container tightly sealed in a low-humidity environment to prevent moisture absorption and caking.
