Products : Cellulose Acetate Phthalate

We provide enteric coating agents and excipients like

  1. Cellulose Acetate Phthalate (C.A.P.) which also plays a pivotal role in gastric fluid resistant coating, sustained release, matrix binder and taste masking for tablets, capsules and pellets is regarded as a non-toxic material free from any adverse effect.
  2. Hydroxy Propyl Methyl Cellulose Phthalate also known as Hypromellose Phthalate or HPMC Phthalate. Hypromellose Phthalate is widely used in oral pharmaceuticals formulations viz..tablets, capsules, pellets, as an enteric coating material, sustained release formulations, matrix former and for taste masking.

C.A.P. as well as Hypromellose Phthalate can be used along with the other excipients like colours, glidants to achieve targeted coating.


Cellulose Acetate Phthalate is our product of repute.
Synonyms: C.A.P. or Cellacefate or Cellacephate or Cellulose Acetate1,2-benzene Dicarboxylate.
CAS No.: 9004-38-0.
