Hydroxyethyl Methyl Cellulose (HEMC)
TENESSY Hydroxyethyl Methyl Cellulose
TENESSY™ Hydroxyethyl Methyl Cellulose (HEMC) is a versatile polymer that dissolves easily in cold water but not in hot water. Its solution is thick and smooth, with excellent flow and viscosity.
Compared with Hydroxypropyl Methyl Cellulose (HPMC), HEMC provides better water retention, viscosity stability, anti-mold properties, and dispersibility.

Key Features of Hydroxyethyl Methyl Cellulose
Why choose Tenessy HEMC?
Main Applications of Hydroxyethyl Methyl Cellulose
TENESSY™ Hydroxyethyl Methyl Cellulose (HEMC) is a versatile ingredient widely used across construction, coatings, and personal care industries. It functions as an efficient thickener, water-retaining agent, film former, and stabilizer. Beyond its role in dry-mix mortars and paints, HEMC is also applied in cosmetics, skincare, and household products to enhance texture, stability, and performance.
Construction Materials
TENESSY™ HEMC is widely used in cement- and gypsum-based products such as tile adhesives, grouts, plaster, waterproof mortars, and self-leveling compounds. It improves water retention, workability, and consistency, ensuring strong bonding and smooth application on site.
Paints and Coatings
In water-based paints, industrial coatings, and inks, HEMC acts as an efficient thickener and stabilizer. It enhances color uniformity, improves coating flow, and prevents pigment settling, helping to create a smooth, even surface finish.
Personal Care and Cosmetics
Oilfield and Drilling
In drilling fluids and muds, HEMC is used as a rheology modifier and water retention agent. It helps control fluid loss, stabilize the mud system, and improve drilling efficiency under various geological conditions.
