ABSTRACT:
High gloss pharmaceutical tablets have an outer coating of sodium carboxymethylcellulose and polyethylene glycol as 0.1 to 5.0% by weight of the tablet. The sodium carboxymethylcellulose has a D.S. between 0.2 and 1.4 and a D.P. between 100 and 4000. Spraying the coating from a water solution eliminates the need for solvent recovery.
