What is ethyl cellulose ethocel?

EC is commonly used as an organosoluble film former, binder, and thickener for a variety of applications including inks, ceramics, and specialty coatings. Ethyl cellulose falls under the ETHOCEL™ line of products from Dupont. ETHOCEL™

What is ethyl cellulose used for?

Ethylcellulose is used in pharmaceutical technology as a coating agent, flavoring fixative, binder, filler, film-former, drug carrier, or stabilizer.

Is ethyl cellulose hydrophilic?

Ethyl cellulose is also a nontoxic, inert hydrophobic polymer widely used in sustained release formulations and to control the dissolution rate of drugs (Quadir et al., 2005.

Is ethyl cellulose safe?

Is EthylCellulose Safe to Eat? Yes, its safety used as a food additive has been approved by the U.S. Food and Drug Administration (FDA), European Food Safety Authority (EFSA), Joint FAO/WHO Expert Committee on Food Additives (JECFA), as well as other authorities.

Is cellulose soluble in ethanol?

Ethyl cellulose is soluble in varying amounts in certain organic solvents, depending upon the ethoxyl content. Ethylcellulose (containing 46- 48% or more of ethoxyl groups) is freely soluble in ethanol, methanol, toluene, chloroform, and ethyl acetate.

What is the nature of ethyl cellulose?

Ethyl cellulose is characterised for being insoluble in water and soluble in organic solvents (such as ethyl acetate) [74,79], so its main advantage is the waterproofing it provides, although it also has excellent mechanical properties [21].

Is ethylcellulose a sugar?

Ethyl cellulose (or ethylcellulose) is a derivative of cellulose in which some of the hydroxyl groups on the repeating glucose units are converted into ethyl ether groups….Ethyl cellulose.

Other names Cellulose, ethyl ether; ethylated cellulose; ethylcellulose; E462
CAS Number 9004-57-3
ChemSpider none

What happens if you eat cellulose?

It’s called cellulose, and you’ve eaten it before. A lot. First the good: Eating cellulose won’t kill you. There are no known harmful side effects from adding it to food, and it’s completely legal.

What can dissolve cellulose?

Basically, cellulose can be dissolved, in some hydrophilic ionic liquids, such as 1-butyl-3-methylimidazolium chloride (BMIMCl) and 1-allyl- 3-methylimidazolium chloride (AMIMCl). Chloride based ionic liquids are suitable solvents for cellulose dissolution.

Which solvent is used for cellulose?

Aqueous solvents for cellulose, e.g., solutions of inorganic salts and complex compounds, were widely used for cellulose regeneration. The best known solvents of this group are cuprammonium hydroxide (Cuam) and cupriethylenediamine hydroxide (Cuen).

Who are the inventors of ethocel cellulose ethers?

ETHOCEL is a trademark of The DuPont Chemical Company for its family of thermoplastic cellulose ethers. These polymers have provided excellent service to industry since their commercial introduction by Dow in the mid-1930s. These multifunctional, water-insoluble, organosoluble polymers are used in many pharmaceutical and specialty applications.

Which is more compatible with ethocel or cellulose?

ETHOCEL polymers yield a greater volume of film-forming solids than any other cellulose derivative. Compatibility – ETHOCEL™ is compatible with most common plasticizers and polymers. It yields clear films with a wider variety of plasticizers and polymers than any other cellulose derivative.

How are fine powder grades of ethocel used?

Fine powder (FP) grades of ETHOCEL™ can be compressed to form hydrophilic matrix tablets for oral controlled release with a non-gel forming mechanism which provides an alternative drug release profile as compared to traditional alternatives. Did you know that ETHOCEL™ Premium Polymers are an excellent choice for a variety of formulation needs?

Why are ethocellulose polymers used in industrial applications?

ETHOCEL™ ethylcellulose polymers are organosoluble products with a narrow specification and uniform ethoxyl functionality. This enables ETHOCEL™ to have very predictable performance, key to industrial applications where the same output is desired batch to batch.
