Sodium carboxymethyl cellulose (CMC) is a versatile compound used in various industries. It's primarily utilized as a thickening agent, stabilizer, and emulsifier in food products, pharmaceuticals, cosmetics, and even in industrial applications like paper and textile manufacturing.
However, sodium carbonyl-methyl cellulose isn't a standard term in chemistry or industry. It seems like a combination of sodium carboxymethyl cellulose and another compound. If you have a specific application or context in mind, please provide more details so I can assist you better.
