MC is a kind of non-ion aqueous cellulous ether,white or white-similar powder or granule,no odor or taste,nontoxic,with a little hygroscopicity. Different substitution offers different solubility,usually medium substitution(DS between 1.5-2.0) comes under cool aqueous model,and finds widest applications.It dissolves in cool water and some organic solvents,does not dissolve in hot water.In hot water at 80-90°C it dissolves and swells,after cooled down,dissolving quick.Its solution possesses reversible hot gelling characteristic,stable to acid and alkali,is not effected between PH 2-12, with excellent anti-mildew ability,capable of dispersing, emulsifying, agglomerating, thickening, holding water,forming film etc.Film formed by its offers superior toughness flexibility, transparency and oil resistance.
