Excipients for Drug Formulation

Kollicoat® MAE 100-55

A complete match – just better. Kollicoat® MAE 100-55 combines two things hard to bring together – it can directly exchange the comparable pH 5.5 enteric release coating polymer in your commercial formulations, and still bring significant handling improvement to your operators because it does not dust at all.

Kollicoat® MAE 100-55 is the latest addition to our comprehensive portfolio of functional excipients in our Instant & Modified Release Platform. It extends our offer of pH >5.5 enteric release products based on methacrylic acid-ethylacrylate copolymer, providing you even more flexibility.

Why choose Kollicoat® MAE 100-55

  • Direct substitution in commercial enteric release formulations based on methacrylic acid-ethylacrylate copolymer with an opening pH > 5.5
  • Easier handling due to dust-free material
  • Compliant with respective monographs

No more dusting thanks to unique powder particle shape

The dry powder particles of Kollicoat® MAE 100-55 are larger and thus significantly less dusty than comparable 100-55 coating grades – much easier to work with for your operators:


Equivalent drug release

Despite its advantages in handling, Kollicoat® MAE 100-55 provides equivalent drug release as existing comparable coating grades in the market. And this means you can directly introduce it into your commercialized formulations.
