Product Detail

Properties

Hydroxyethyl Methyl Cellulose (MHEC/ HECM)

MHEC is non-ionic cellulose ether made from natural cotton fiber under series of chemical processing.

It’s odorless, tasteless and non-toxic white powder, can be dissolved in normal water to form a transparent

viscous solution with the properties of thickening, binding, dispersing, emulsifying, film coating, suspending, absorbing, gelling, water retention and colloid protection.

Properties

Methyl 2-Hydroxyethyl Cellulose is a odorless, tasteless and non-toxic white powder, which can be dissolved in cold water to form a transparent viscous solution. It has the characteristics of thickening, bonding, dispersion, emulsification, film-forming, suspension, adsorption, gelation, surface activity, water retention and colloid protection. Because aqueous solution has surface active function, it can be used as colloidal protective agent, emulsifier and dispersant. Hydroxyethyl methylcellulose aqueous solution has good hydrophilicity and is a high-efficiency water retaining agent. Hydroxyethyl methyl cellulose contains hydroxyethyl group, so it has good mildew resistance, good viscosity stability and mildew resistance during long-term storage.
