Ethyl methyl cellulose

Ethyl methyl cellulose (CAS 9004-59-5), also known by the food additive designation E465, is a mixed cellulose ether produced by introducing both ethyl and methyl substituents onto the cellulose backbone.

Where is Ethyl methyl cellulose used?

• Food manufacturing: E465 stabilizes emulsions and controls texture in processed products
• Pharmaceutical tablets and coatings: film-former and binder for controlled release and coating integrity
• Construction mortars and tile adhesives: improves workability and water retention, extending open time
• Coatings and textile finishing: adjusts flow behavior and improves substrate adhesion
• It functions as a rheology modifier, emulsifier, and water-retention agent.

Good to know: Higher-viscosity grades are suited to construction and industrial applications, while lower-viscosity grades are preferred in food processing. Store in a cool, dry environment to maintain chemical stability.

Commercial specifications

• Food-grade material to E465 specification
• Pharmaceutical-grade supply meets USP and Ph. Eur. standards
• Packaging in multi-wall bags or fiber drums, with bulk quantities for industrial procurement
