Name: Eastman C-A-P NF Cellulose Acetate Phthalate
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Eastman C-A-P NF Cellulose Acetate Phthalate

Enteric coating polymer compliant with United States National Formulary (NF) and FDA requirements for pharmaceutical use.
Provides pH-dependent solubility—insoluble in gastric fluid (pH < 5.5), rapidly dissolves in intestinal fluid (pH ≥ 6.0).
Offers excellent film-forming capability with good mechanical strength and low moisture permeability.
Compatible with common plasticizers (e.g., triethyl citrate, acetyl tributyl citrate) and widely used excipients.
Supplied as a free-flowing, off-white to light tan granular solid with consistent batch-to-batch performance.

Typical Applications Of Eastman C-A-P NF Cellulose Acetate Phthalate

Enteric-coated tablets and capsules for targeted drug release in the small intestine.
Functional barrier coatings in oral solid dosage forms to prevent gastric degradation of acid-labile APIs.
Coating agent for taste-masking and moisture protection of bitter or hygroscopic active ingredients.
Matrix former in sustained-release multiparticulate systems (e.g., coated pellets and beads).
