Klucel MS HPC is a non-ionic water-soluble cellulose ether with a versatile combination of properties.
(12) Among the cellulose ether derivatives, hydroxypropyl methyl cellulose (HPMC) has been widely investigated for its drug-releasing effect as compared with methyl cellulose and hydroxypropyl cellulose (HPC).
Likewise, organic chemicals are further divided into carbohydrates including sugar (actual sugar, sugar alcohol, artificial sweetener), starch (modified, converted, dried) and cellulose (cellulose ether, cellulose ester, croscarmellose sodium, microcrystalline cellulose), petrochemicals including glycol (polyethylene, propylene glycol), povidone, mineral hydrocarbons (petrolatum, mineral waxes, mineral oils), acrylic polymers, others (antimicrobials, antioxidants, dyes & lakes), oleochemicals including fatty alcohol, mineral stearate, glycerin and others (alcohol, citric acid, lactic acid, polysaccharide gums, Shellac), proteins including gelatin and others including water for injection and purified water.
CMC is able to improve the mechanical and barrier properties of pea starch-based films [4]; Because of its pronounced visco- elastic and structure-forming properties, the cellulose ether sodium carboxymethylcellulose (Na-CMC) is employed as a flow enhancer, stabilizer, and also as an agent for binding, suspending and thickening.
Summary: Macromolecular prodrugs (MPDs) of mefenamic acid were designed onto a cellulose ether derivative hydroxypropylcellulose (HPC) as ester conjugates.
Candidate materials for spinning include polyolefins, polyacetals, polyamides, polyesters, cellulose ether and esters, polyalkylene sulfides, polyarylene oxides, and polysulfones.
% of a thermoplastic cellulose selected from cellulose ether and cellulose alkanoate with 2 to 10 carbons in an alkano-ate group having a melting point temperature between about 100[degrees] C.
A review of cellulose ether in hydrophilic matrices for oral controlled release dosage forms.
It has been the most important ionic cellulose ether with a worldwide annual production of 300,000 tons .
(OTC Bulletin Board: CRUI), a manufacturer and distributor of cellulose ether additives for use in the production of pharmaceuticals, construction materials, polyvinyl chloride products, foods, beverages and cosmetics, has announced its financial results for the second quarter of 2011.
Processing is easier, and costs are lower than for the common sauce binder and the cellulose ether. As the Purafarin[R] product has a high opacity and creates a creamy full-bodied mouthfeel, the content of cream or creme fraiche in soups can be significantly reduced while achieving the same results.
Larger molecules such as cellulose ether and xanthum gum increased viscosity, but did not cut diffusion rates.
