Refined cotton Ethyl Cellulose for Cosmetics CAS 9004-57-3

Ethyl Cellulose (EC), the ethyl ether of cellulose, is a cellulose derivative in which ethoxy groups replace the hydroxyl groups, with different molecular weights and viscosities. Ethyl cellulose is white granules or powder, odorless and tasteless; easily soluble in toluene or ether, soluble in dichloromethane, slightly soluble in ethyl acetate and methanol, insoluble in water, glycerol and propylene glycol;

Ethyl cellulose is stable, resistant to alkali and salt, and is more sensitive to acid than cellulose ester. In addition, the viscosity of ethyl cellulose solution is related to the concentration and solvent type, and the viscosity of the solution increases with the increase of concentration.
