Methyl hydroxyethyl cellulose (HEMC), as a high-performance non-ionic cellulose ether, has been widely used in various industrial and consumer sectors due to its excellent thickening, water retention, dispersing, emulsifying, and film-forming properties.
Main application areas
Construction and building materials industry: HEMC is a core additive in dry-mix mortar, tile adhesive, putty powder, self-leveling flooring, and other products. It can significantly improve the 24-hour water retention rate of mortar (>85%), prevent early water loss and cracking, and enhance construction cohesion and anti-slip properties. It can maintain a moisture content of over 85% even under high-temperature exposure, effectively preventing hollow areas and detachment.
Coatings and Ink Industry:
In water-based latex paints, HEMC provides excellent thickening and rheology control properties, achieving a single coat thickness of up to 200 μm and improving anti-sagging properties by 40%. In artistic paints, it can improve the alignment precision of pearlescent powder by 3 times, enhancing visual texture. It is also used in printing inks to prevent pigment sedimentation and improve storage stability.
Pharmaceutical and Pharmaceutical Industry:
HEMC is non-toxic and non-irritating, listed as a GRAS (Generally Recognized As Safe) substance, and widely used as a sustained-release excipient in oral tablets and suspensions. It can achieve a stable release for 12 hours, with a blood drug concentration fluctuation CV% ≤ 15%, significantly improving medication safety and compliance.
Food Industry:
As a food additive, HEMC is used as a thickener, stabilizer, and anti-melting agent. In ice cream, it can control ice crystal size to <15μm, improving melt resistance by 60% and resulting in a smoother, more delicate texture. It can also be used in jams and sauces to improve texture and suspension stability.
Daily Chemicals:
Widely used in toothpaste, facial cleansers, shower gels, cosmetics, and other products as a thickener, emulsifier, and moisturizer. Its excellent pseudoplasticity makes products easy to extrude and spread, forming a thin, breathable protective film and improving the user experience.
Oil Drilling and Oilfield Development:
HEMC possesses excellent salt resistance and high-temperature stability, maintaining viscosity stability even at 120℃ and high salinity. It is used for thickening drilling fluids, reducing filtration loss, and suspending cuttings, ensuring drilling safety.
