:Cellulose acetate phthalate
Description:
Cellulose acetate phthalate (CAP) is a synthetic polymer derived from cellulose, characterized by the esterification of cellulose with phthalic anhydride. It is primarily used as a film-forming agent and is notable for its ability to form clear, flexible films. CAP is soluble in organic solvents such as acetone and ethanol, but is insoluble in water, making it useful in pharmaceutical applications, particularly for enteric coatings that protect drugs from gastric acid. This property allows for the controlled release of active ingredients in the intestinal environment. CAP is also valued for its biocompatibility and biodegradability, making it suitable for various applications in the biomedical field. Additionally, it exhibits good thermal stability and can be processed into various forms, including powders and films. Its use extends to food packaging and coatings, where it serves to enhance moisture resistance and prolong shelf life. Overall, cellulose acetate phthalate is a versatile polymer with significant applications in pharmaceuticals, food technology, and materials science.

CAS:<p>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).</p>Purity:Min. 95%
