FINCELO® EC for PHARMACEUTICAL application
FINCELO EC pharmaceutical series are ethyl cellulose. Ethylcellulose, taking natural cellulose as the main raw material, is organic-soluble cellulose ether produced by a series of chemical reactions, belonging to nonionic cellulose ethers. The appearance of EC is white to slight yellow powder or granules without smell and taste.
EC has small moisture absorption, good electrical properties and good stability to light, heat, oxygen, damp and chemicals. It is nonflammable and tolerant to strong base, diluted acid and brine solution. It can be soluble in organic solvents like alcohols, ethers, ketones, esters, arenes, halohydrocarbons, etc.
