Methyl 2-hydroxyethyl cellulose Usage And Synthesis
  • Chemical Propertiessoluble in cold water, flocculates at elevated temperatures
  • Chemical PropertiesA white, yellowish-white or grayish-white powder or granules, hygroscopic after drying.
  • UsesWater retention aid, thickening agent, protective colloid, suspending agent, binder and stabilizer.
  • Pharmaceutical ApplicationsHydroxyethylmethyl cellulose is used as an excipient in a wide range of pharmaceutical products, including oral tablets and suspensions, and topical gel preparations. It has similar properties to methylcellulose, but the hydroxyethyl groups make it more readily soluble in water and solutions are more tolerant of salts and have a higher coagulation temperature.
  • SafetyHydroxyethylmethyl cellulose is used as an excipient in various oral and topical pharmaceutical preparations, and is generally regarded as an essentially nontoxic and nonirritant material.
  • storageHydroxyethylmethyl cellulose is hygroscopic and should therefore be stored under dry conditions away from heat.
  • Regulatory StatusGRAS listed. Included in nonparenteral medicines licensed in Europe (oral suspensions, tablets, and topical preparations).
