Soluble in water to form colloidal solution, optical, thermal stability. Not soluble in ethanol, ether, chloroform and other organic solvents. This product is water solution in alkaline solution is stable in acid, poor, generating free acid does not dissolve in water, the viscosity decreases, therefore does not apply to Yu *** acid food. In aqueous solution at 80 degrees above the long time heating, viscosity reducing. This product and carboxymethyl cellulose ( CMC ) has similar performance, with thickening, suspension, dispersion, emulsion, adhesive, water retention, protective colloid properties. Can be used as emulsifier, thickener, stabilizer, dispersing agent, sizing agent, film forming agent, water retaining agent, widely used in petroleum, chemical, textile, tobacco, paper, c***truction, food, pharmaceutical and other industrial sectors, known as the "industrial msg". It is a substitute of CMC. In some areas can replace pva. Unlike CMS, aqueous solution of the goods will be the bacteria in the air component decomposition (producing amylase ) is easily liquefied, viscosity reduction. Thus prepared in aqueous solution is not easy to be stored for a long time, not easy for ketchup. ? title] dissolution method: according to the required concentration, than by adding water to the case of fully mixing can be completely dissolved. Or first with ethanol wet, then dissolved in water is better. Quality standard: Q / X with R004-1999 regulati***; index: food grade engineering industry; appearance: white or light yellow powder. Drilling fluid with carboxymethyl starch CS product performance: carboxymethyl starch ( CS ) is a modified starch is a starch product, ethers, is a water soluble anionic polymer, odorless, tasteless, non-toxic, heat absorption of moisture. Water soluble form colloidal soluti***, light, thermal stability. Not soluble in ethanol, ether, chloroform and other organic solvents. With thickening, suspension, dispersion, emulsion, adhesive, water retention, protective colloid properties. Can be used as emulsifier, thickener, stabilizer, dispersing agent, sizing agent, film forming agent, water retaining agent.
