Ethyl cellulose

Ethyl cellulose

EC; Cellulose ethyl ether; Ethyl cellulose polymer; Ethylcellulose

CAS 9004-57-3

Chemical Formula (C12H20O6)n (generalized polymer formula)

Molecular Weight Variable; depends on viscosity grade (typically 80,000–500,000 g/mol)

Ethyl cellulose is a tasteless, odorless, and non-toxic white to light tan powder derived from cellulose. It is widely used as a thickener, film-former, binder, and coating agent in industries such as pharmaceuticals, food, cosmetics, and coatings. Known for its excellent flexibility and water resistance, Ethyl cellulose is valued for creating sustained-release drug formulations, clear coatings, and stable emulsions.

Industrial Uses

1. Pharmaceuticals

  • Film Coating Agent: Used to coat tablets and capsules for controlled or sustained drug release.
  • Binder in Tablets: Functions as a binder in tablet formulations for improved mechanical strength.
  • Controlled Release Matrix: Employed in matrix systems to regulate drug release over time.
  • Taste Masking Agent: Masks unpleasant tastes of active pharmaceutical ingredients.

2. Performance Chemicals

  • Polymer Base: Acts as a base polymer for the synthesis of specialty cellulose derivatives.
  • Additive in Resin Systems: Used to enhance flexibility and reduce brittleness in resins and coatings.

3. Construction

  • Modifier in Cement and Mortar: Improves workability, water retention, and adhesion in cement-based products.
  • Additive in Tile Adhesives & Grouts: Enhances spreadability and bond strength of dry-mix construction materials.

4. Agrochemicals

  • Coating for Controlled Release Fertilizers: Provides a protective film that enables slow nutrient release.
  • Suspension Stabilizer in Pesticides: Helps maintain uniform dispersion of active ingredients in liquid pesticide formulations.

5. Paints, Coatings & Adhesives

  • Rheology Modifier: Improves the viscosity and application properties of adhesives and sealants.
  • Film Former: Used in solvent-based adhesives as a clear, flexible film-forming agent.

6. Personal Care

  • Film Former in Cosmetics: Provides water-resistant, flexible films in products like mascara and sunscreens.
  • Stabilizer in Creams and Lotions: Enhances the stability and texture of emulsions.
