  • Hydroxyethyl cellulose (HEC) is a popular and versatile compound used in a wide range of industries. It is a non-ionic, water-soluble polymer that is derived from cellulose through a chemical modification process. HEC is known for its excellent thickening, stabilizing, and water retention properties, making it a valuable ingredient in various applications.
  • This substitution process results in a polymer with a backbone of glucose units, with hydroxyethyl groups attached to each anhydroglucose unit. The degree of substitution (DS) indicates the number of hydroxyl groups that have been replaced by hydroxyethyl groups, and it plays a critical role in determining the solubility and rheological properties of the final product. Typically, HEC has a DS ranging from 0.5 to 2.5.

  • The production of hydroxyethyl cellulose is subject to stringent quality standards to ensure its safety and efficacy across various applications. Manufacturers often comply with regulations imposed by agencies such as the Food and Drug Administration (FDA) for pharmaceutical and food-grade HEC, as well as the European Medicines Agency (EMA) guidelines. Additionally, standard testing methods are utilized to evaluate the viscosity, purity, and microbial load of HEC.
