Product Details

Hydroxyethyl methyl cellulose ether, referred to as HEMC, is a non-ionic cellulose ether obtained from natural polymer material cellulose through a series of chemical reactions. It is an odorless, tasteless, non-toxic white to off-white powder or granule, which can be dissolved in cold or hot water to form a transparent viscous solution, which has the functions of thickening, binding, water retention, dispersion, emulsification and film formation. , suspension, adsorption, colloid protection, etc
