Study Set Content:
Thick syrup, plus starch and calcium carbonate to dusting powder in between coatings
Smoothing and final rounding
cameube wax and /or bees wax talc contributes to their high luster
Polishing
thin, skin-tight coating of a plastic-like material
over the compressed tablet
Film-coating
Produce smooth, thin films
Film former
Provide water solubility or permeability to the film to ensure penetration by body fluids
Alloying substance
Produce flexibility, elasticity, durability of the coating
Plasticizer
Enhance spreadability of the film
surfactant
film former example
cellulose acetate phthalate
Plasticizer example
castor oil
alloying substance example
polyethylene glycol
surfactant examples
polyoxyethylene sorbitan derivatives
improve appearance
opaquants and colorants
enhance palatability
sweeteners, flavors, and aromas
provide luster to the tablets
Glossant
allow spreading on the tablet surface and promote evaporation
