sodium carboxymethyl cellulose

Sodium carboxymethyl cellulose (CMC-Na) bụ a carboxymethylated mmepụta nke cellulose na bụ kasị mkpa ionic cellulose gum. Sodium carboxymethyl cellulose na-abụkarị ogige anionic polymer nke a kwadebere site n'imeghachi cellulose eke na caustic alkali na monochloroacetic acid, nke nwere ibu molekụla sitere na ọtụtụ puku ruo nde. CMC-Na bụ ọcha fibrous ma ọ bụ ntụ ntụ ntụ, enweghị isi, enweghị ụtọ, hygroscopic, dị mfe ịgbasa na mmiri iji mepụta ngwọta colloidal transperent.
