Methyl cellulose (MC) is the most important commercial cellulose ether. It is also the simplest derivative where methoxy groups have replaced the hydroxyl groups. The most important properties of this nonionic polymer are its water solubility and its gelation when exposed to heat. Although soluble in water, films made from methyl cellulose usually retain their strength and do not become tacky when exposed to humidity.Ã?Â
These water soluble polymers are excellent thickeners, binders, and film formers for a variety of applications including ceramic extrusion, adhesives, coatings, inks, and agrochemicals. Solutions of methylcellulose will reversible gel under heat to a rigid gel structure providing a controllable boost in green strength.
showed physical inertia, in the pharmaceutical, food and cosmetics are widely used as thickener, protective colloid, auxiliary emulsifiers, pigment, adhesive and film-forming agent tablets. Also be used for the substrate suspension or viscous eye drops, and as drug stabilizers, oral laxative, gargle Contact lens wetting solution and the cornea of the main raw material, also used as a reinforcing material. Preparation of methyl cellulose sustained-release hydrophilic matrix agents, microporous film or multilayer coating film release formulations.

Product Name: Hydroxypropyl methyl cellulose/Hypromellose Other Name: hpmc powder Molecular Formula: C3H7O Molecular Weight: 59.08708 Appearance: White Powder Purity: 99% CAS NO.: 9004-65-3 EINECS No.: 618-389-6 Supplier: ZHENYIBIO Hydroxypropyl Methyl Cellulose (HPMC) are water soluble polymers derived from cellulose. They are typically used as thickeners, binders, film formers, and water retention agents. They also function as suspension aids, surfactants, lubricants, protective colloids, and emulsifiers. In addition, solutions of these polymers thermally gel.
Hydroxypropyl Methylcellulose (HPMC) are non-ionic cellulose ether & its derivatives that have hyrdroxyl groups on the cellulose chain substituted for a methoxy or hydroxypropyl group. HPMC is made from natural cotton linter under chemical reaction, which can be dissolved in both cold water and hot water to form a transparent solution. HPMC is used as a thickener, binder, and film former in construction, pharmaceutical, food, cosmetic, detergent, paints, adhesives, inks, PVC and various other applications.
Hydroxyethyl Methyl Cellulose (MHEC) are water-soluble nonionic cellulose ethers, which are offered as free-flowing powder or in granular form cellulose. Hydroxyethyl Methyl Cellulose(MHEC) is made from highly pure cotton-cellulose by reaction of etherification under alkaline conditions without any organs of animals, fat and other bioactive constituents. MHEC appears to be white powder and is odorless and tasteless. It is featured by hygroscopicity and hardly soluble in hot water, acetone, ethanol and toluene. In cold water MHEC will swell into colloidal solution and its solybility is not influenced by PH value. Similar to methyl cellulose while being added to Hdroxyethyl groups. MHEC is more resistant to saline, easily soluble in water and has higher gel temperature. MHEC is also known as HEMC, Methyl Hydroxyethyl Cellulose ,which can be used as high efficient water retention agent, stabilizer, adhesives and film-forming agent in construction, tile adhesives, cement and gypsum based plasters, liquid detergent ,and many other applications.

Carboxy Methyl Cellulose ( CMC ) is synthesized by the alkali-catalyzed reaction of cellulose with chloroacetic acid. The polar (organic acid) carboxyl groups render the cellulose soluble and chemically reactive. The functional properties of Fooding Carboxy Methyl Cellulose(CMC) depend on the degree of substitution of the cellulose structure (i.e., how many of the hydroxyl groups have taken part in the substitution reaction), as well as the chain length of the cellulose backbone structure and the degree of clustering of the carboxymethyl substituents.
