The aqueous solution to barrier membrane coating


Aquacoat® sustained release coating is a pseudo latex aqueous dispersion of water insoluble polymers used for sustained and enteric coating applications.

Aquacoat® ECD is an aqueous dispersion of ethylcellulose used for sustained release barrier or slow release pharmaceutical coating, moisture barrier and taste masking applications for tablet and multi-particulate dosage forms. Aquacoat® CPD is an aqueous dispersion of cellulose acetate phthalate used for enteric release applications. This grade of polymer film remains intact at pH< 6, thus protecting the API in gastric environments.

Stable and flexible barrier membrane coating

In sustained release applications or modified release drugs, Aquacoat® ECD offers a stable, reproducible, pH-independent release profile with similar dissolution profiles in the presence of fed and fasted gastric and intestinal media. Its primary release mechanism is drug diffusion across a water-insoluble membrane.
