1. HEMC hydroxyethyl methyl cellulose is made from Highly pure cotton cellulose. After alkali treatment and special etherification becomes HEMC. It does not contain any animal fats and other active ingredients.
2. The appearance of HEMC is white particles or powder, odorless and tasteless. It is hygroscopic and can not dissolve in hot water, acetone. ethanol and toluene. After swelling in cold water into a colloidal solution, dissolving is not affected by PH value. It is similar to methyl cellulose, but with the increase of hydroxyethyl groups, it has more tolerance, more easily soluble in water and has a higher condensation temperature.
