DEP in Pharmaceuticals

Tablet coatings, capsule manufacturing, controlled-release drug delivery

Pharmaceutical manufacturers require excipients that meet the strictest quality and regulatory standards. DEP has a long history of safe use as a plasticizer in oral dosage forms.

Applications

How DEP Serves This Industry

Tablet Film Coatings

DEP plasticizes cellulose-based coating polymers (HPMC, ethyl cellulose), creating smooth, uniform films that protect active ingredients and control release profiles.

Capsule Manufacturing

Used as a plasticizer in hard and soft gelatin capsule production, improving flexibility and reducing brittleness during storage and handling.

Controlled-Release Formulations

DEP modifies the permeability of polymer matrices in sustained-release dosage forms, enabling precise drug release over extended periods.

Enteric Coatings

Plasticizes pH-sensitive polymers used in enteric coatings, ensuring tablets survive gastric acid and release their payload in the intestine.

Regulatory

Regulatory Notes

DEP meets USP/NF and Ph.Eur monograph specifications. Not classified as CMR under CLP. Acceptable for use as a pharmaceutical excipient in the EU.
