Eastman™ C-A-P (Cellulose Acetate Phthalate, NF) enteric coating material is a pH-sensitive cellulose derivative designed for coating pharmaceutical tablets, capsules or granules. It may also be used as a matrix material in solid dose forms. C-A-P enteric coating material withstands prolonged contact with acidic gastric fluids, but it dissolves readily in the mildly acidic to neutral environment of the small intestine. It can be applied to tablets, capsules or granules from solutions of organic solvents. C-A-P meets USP and NF specifications and is available in powder and pellet form.
