EHEC and MEHEC cellulose ethers

Bermocoll® EHEC (ethyl hydroxyethyl cellulose) and MEHEC (methyl ethyl hydroxyethyl cellulose) are non-ionic cellulose ethers, manufactured by a unique, solvent-free process, ensuring you a low carbon footprint and cellulose with carefully calculated performance characteristics.

We are the only producer in the world of EHEC and MEHEC. These are manufactured using cellulose from wood or cotton linters via alkalization, ethoxylation and reaction with ethyl- and methyl-chloride.

EHEC and MEHEC can also be reacted with longer chain hydrophobes, producing hydrophobically modified cellulose, HM-(M)EHEC, used as associative thickeners.

Our Bermocoll® products are used as rheology modifiers in a variety of industrial applications to create desired performance enhancements for both drymix mortars and paints.

Cellulose is extracted from deciduous timber, coniferous timber or cotton using a thermocatalytic process.

Various cellulose derivatives can then be synthesized by modifying the chemical structure of cellulose, a fully plant-based substance. This involves partially or completely substituting the hydrogen atoms of the hydroxyl groups with alkyl groups.

This process of generating cellulose ether is called etherification. The properties of the resulting substance depend on the average degree of substitution, degree of molar substitution, number of hydroxyl groups and the distribution of the substituted groups.

There are many types of cellulose ether, including:

• Carboxymethyl cellulose (CMC)
• Methyl cellulose (MC)
• Ethyl cellulose (EC)
• Hydroxyethylcellulose (HEC)
• Hydroxypropyl methylcellulose (HPMC)
• Methyl hydroxypropyl cellulose (MHPC)
• Ethyl hydroxyethyl cellulose (EHEC)

Whether a cellulose ether is soluble in water or other mediums depends on the number and product type of ether groups, depending on the end-use. A low degree of etherification results in a cellulose ether that can dissolve in aqueous solutions, while a high degree of etherification makes the product soluble in nonpolar solvents. Using more than one etherification agent will result in a mixed cellulose ether.
