Cellulose acetate hydrogen phthalate

Cellulose acetate phthalate (CAP) finds use in the formulation of pharmaceuticals, such as the enteric coating of tablets or capsules and for controlled release formulations, where it is often used with other coating agents such as ethyl cellulose.  It contains about 50% acetate and 25% as the phthalate ester with the rest as free hydroxyl groups.  Enteric coatings based on CAP are resistant to acidic gastric fluids, but easily soluble in mildly basic medium of the intestine. The pH-sensitive solubility of CAP is mainly determined (as are other properties of this mixed ester) by the degree of substitution and by the molar ratio (acetyl and phthaloyl groups).
