cmc is an organic substance, and its Chinese name is sodium carboxymethyl cellulose.
sodium carboxymethylcellulose (CMC), a carboxymethylated derivative of cellulose, also known as cellulose gum, is the main ionic cellulose gum. CMC was first made in Germany in 1918, patented in 1921, and then commercialized in Europe. At that time, it was only a crude product, used as colloid and binder. From 1936 to 1941, the research on the industrial application of CMC was quite active, and several enlightening patents were published.
application of p>cmc
1. application of sodium carboxymethyl cellulose in food industry: sodium carboxymethyl cellulose is not only a good emulsion stabilizer and thickener in food application, but also has excellent freezing and melting stability, which can improve the flavor of products and prolong storage time.
2. Application of sodium carboxymethyl cellulose in pharmaceutical industry: it can be used as emulsion stabilizer for injection, binder and film-forming agent for tablets in pharmaceutical industry.
3. CMC can be used as anti-settling agent, emulsifier, dispersant, leveling agent and adhesive for coatings, which can make the solid part of coatings evenly distributed in solvents, so that the coatings will not delaminate for a long time, and it is also widely used in paints.
