HPMC Phthalate is a chemically modified cellulose polymer primarily used as an Enteric Coating Agent in oral pharmaceutical formulations. Its vital function is to shield the Active Pharmaceutical Ingredient (API) from the harsh acidic environment of the stomach, or to protect the stomach from the irritating effects of the drug. The 55 grade is characterized by pH-Dependent Solubility, remaining intact in acidic gastric fluid ($\text{pH} < 5$) and beginning to dissolve rapidly upon entering the small intestine ($\text{pH} > 5.5$).
Enteric coating for acid-sensitive APIs (e.g., enzymes or certain antibiotics).
Provides superior protection from stomach acid with rapid dissolution in the intestines.
As a coat for pellets within capsules.
Allows for the preparation of delayed enteric release formulations with precise control over the release site..
Coating of gastric irritants (e.g., $\text{NSAIDs}$).
Prevents release in the stomach, minimizing nausea and ulceration.
he product fully complies with the requirements specified in the United States Pharmacopeia (USP), the European Pharmacopoeia (EP), and/or other relevant standards.
Strict control over viscosity is maintained to ensure easy spray application on tablets and consistency in film thickness.
Precise determination of the phthalate ratio is critical to guarantee the specific $\text{pH} 5.5$ performance and compliance with safety requirements.
Production is conducted in a rigorous cGMP environment, ensuring consistency in physical properties.
