Ethylcellulose Polymers – An Excellent Choice for a Variety of Formulation Needs


What is it?

ETHOCEL™ premium ethylcellulose resins are water-insoluble polymers. They are soluble in a wide range of organic solvents, beginning with aliphatic alcohols such as ethanol and isopropanol, and are compatible with most other familiar organic solvent chemistries, including ether alcohols, ketones, aromatic hydrocarbons and many more.

Their excellent compatibility allows use of ETHOCEL™ polymers with many basic ingredients across a broad array of pharmaceutical applications such as controlled-release matrix systems, multi-particulate coatings, and microencapsulation. They are also useful as granulation binders, as film-formers to improve tablet integrity and appearance, and in taste-masking of actives.
