Cros Carmellose is made by first soaking crude cellulose in sodium hydroxide, and then reacting the cellulose with sodium monochloroacetate to form sodium carboxymethyl cellulose. Excess sodium monochloroacetate slowly hydrolyzes to glycolic acid and the glycolic acid catalyzes the cross-linkage to form croscarmellose sodium. Chemically, croscarmellose sodium is the sodium salt of a cross-linked carboxymethylated cellulose. Croscarmellose sodium is an internally cross-linked sodium carboxymethylcellulose.

The cross linking reduces water solubility while still allowing the material to swell and absorb many times its weight in water. As a result, it provides superior drug dissolution and disintegration characteristics. Croscarmellose Sodium also resolves formulators concerns over long term functional stability, reduced effectiveness at high tablet hardness levels, and similar problems associated with other products. Croscarmellose Sodium is developed to enhance drug dissolution

We are offering hydrochloric acid. Hclhydrochloric acid is a clear, colorless, highly pungent solution of hydrogen chloride (hcl) in water. It is a highly corrosive, strong mineral acid with many industrial uses. Bulk industrial-grade is therefore 30% to 34%.hydrochloric acid is a strong inorganic acid that is used in many industrial processes such as refining metal. The application often determines the required product quality. One of the most important applications of hydrochloric acid is in the pickling of steel, to remove rust or iron oxide scale from iron or steel before subsequent processing, such as extrusion, rolling, galvanizing, and other techniques.the spent acid has long been reused as iron(ii) chloride (also known as ferrous chloride) solutions.the steel pickling industry has developed hydrochloric acid regeneration processes, such as the spray roaster or the fluidized bed hcl regeneration process, which allow the recovery of hcl from spent pickling liquor. The most common regeneration process is the pyrohydrolysis process.another major use of hydrochloric acid is in the production of organic compounds, such as vinyl chloride and dichloroethane for pvc. Other organic compounds produced with hydrochloric acid include bisphenol a for polycarbonate, activated carbon, and ascorbic acid, as well as numerous pharmaceutical products. Numerous products can be produced with hydrochloric acid in normal acid-base reactions, resulting in inorganic compounds. These include water treatment chemicals such as iron chloride and polyaluminium chloride (pac).both iron chloride and pac are used as flocculation and coagulation agents in sewage treatment, drinking water production, and paper production.hydrochloric acid can be used to regulate the acidity (ph) of solutions.
