Ethyl Cellulose, Cellulose Ethyl Ether
Ethyl Cellulose, Cellulose Ethyl Ether-CAS 9004-57-3
Ethyl Cellulose is a non-ionic cellulose ether polymer modified from natural cellulose through ethylation reaction. As a high-performance eco-friendly raw material, it features stable chemical properties, low moisture absorption and outstanding film-forming ability. It can form uniform, tough, waterproof and breathable protective films on material surfaces. With excellent thickening, bonding and dispersion effects, it has strong alkali resistance and wide solvent compatibility. It is widely applied in cosmetics, daily chemicals, coating and ink industries, serving as an ideal functional additive for improving product surface texture and system stability.
Key Benefits
• Superior Film-Forming Performance: Forms transparent, tough and flexible films with good waterproof and anti-scratch effects.
• Low Moisture Absorption & High Stability: Ultra-low hygroscopicity, stable physical and chemical properties in variable temperature and humidity environments.
• Excellent Thickening & Bonding: Provides stable thickening and adhesive effects for coatings, inks and cosmetic formulas.
• Strong Chemical Resistance: Outstanding alkali resistance and good tolerance to conventional organic solvents.
• Good Processability: Easy to dissolve and disperse, suitable for industrial mixing, coating and film-forming processing.
• Non-Toxic & Eco-Friendly: Harmless to human body and environment, compliant with global green raw material standards.
Applications
• Cosmetic Film-Forming Agent: Used in long-lasting makeup, nail polish and hair styling products to form breathable and wear-resistant protective films.
• Coating & Paint Industry: Serves as thickener and film former for industrial paints, architectural coatings and waterproof coatings.
• Printing Ink Additive: Improves ink adhesion, leveling property and drying speed, preventing ink peeling and fading.
• Plastic & Polymer Modification: Enhances plastic surface toughness, dimensional stability and anti-aging performance.
• Textile Industrial Auxiliaries: Used as textile sizing and finishing agent to improve fabric surface flatness and wear resistance.
