General description

Ethyl cellulose is a non-toxic polysaccharide type gelator widely used in surface coatings and biomedical applications.

Application

Ethyl cellulose can be used:
  • To prepare oleogels for the ophthalmic delivery of hydrophilic drugs.
  • As a coating agent to synthesize flexible bioplastics for packaging applications.
  • To prepare CuO/Cu2O granules for thermochemical heat storage applications.
