Importance of cellulose esters

Eastman offers different grades of cellulose esters to address varying performance and productivity requirements. Our cellulose esters form a semipermeable film membrane that can be laser drilled or used with pore formers for osmotic pump coatings and dosage forms.

Our cellulose portfolio

Our portfolio includes cellulose acetate (CA) and cellulose acetate butyrate (CAB or cellaburate) to help achieve patient compliance by enabling extended/sustained-release dosage forms.

Excellent film formers

Our cellulose ester excipients are excellent film formers that enable zero-order release of a drug.

Osmotic pump dosage

Formulators dealing with a narrow/tight therapeutic index can formulate an osmotic pump dosage form using Eastman cellulose esters.

Delayed drug release

Our cellulose acetate phthalate polymer is a well-known enteric coating polymer excipient that enables enteric and delayed release of a drug.

Protective coating

Cellulose acetate phthalate can also be used as a protective/taste-masking coating that keeps the drug from being released in the acidic stomach environment.

Dissolution profiles

Blends of cellulose acetate phthalate and either CA or CAB can be used to formulate tablet coatings that display a wide range of dissolution profiles.

Given customer input of how much drug is to be delivered over time, starting formulations can be predicted using Eastman’s unique algorithms.
