Coating agents cellulose acetate phthalate

Cellulose (Figure 8.19) may be extracted from wood pulp, and is usually partially hydrolysed with acid to give microcrystalline cellulose. These materials are used as tablet diluents. Semi-synthetic derivatives of cellulose, e.g. methylcellulose, hydroxymethylcellulose, and carboxymethylcellulose, are used as emulsifying and suspending agents. Cellulose acetate phthalate is cellulose with about half the hydroxyl groups acetylated, and the remainder esterified with phthalic acid. It is used as an acid-resistant enteric coating for tablets and capsules. [Pg.476]

In addition to its renewability and satisfactory mechanical properties, cellulose presents biocompatibility, which makes it possible to use in some pharmaceutical applications. Different chemical modifications allow different applications of cellulose, such as oxycellulose for controlled drug delivery matrices, sodium carboxymethyl cellulose as emulsifying agents, and cellulose acetate phthalate for tablet coatings (Kamel et al, 2008).
