HPMCAS for Enteric Delivery Application


What is it?

ENTERACT™ polymers are fine grades of Hypromellose Acetate Succinate (HPMCAS) tailored for delivery needs in delayed (enteric) coating applications.

What is it used for?

ENTERACT™ polymers demonstrate enteric performance, ensuring that the API is protected through the upper gastrointestinal tract.   The three  different grades include ENTERACT™ AS 716 F, 912 F and 126 F.


HPMCAS-based enteric coatings can provide the following advantages:

  • Low reactivity with select APIs
  • Low tackiness of applied coatings
  • Flexible coatings (e.g.soft gels)
  • Phthalate-free enteric drug delivery
