### Product Introduction
Mixed fatty acid glycerides(stearin) are semi‑synthetic lipid pharmaceutical excipients, manufactured by alcoholysis and distillation of hydrogenated vegetable oil.
Different melting‑point grades are obtained by adjusting fatty‑acid carbon‑chain distribution. It features good biocompatibility, stable property, low rancidity risk, good compatibility with most pharmaceutical raw materials. It melts at human‑body temperature, classic suppository matrix raw‑material. Also used as softening & curing agent in cosmetics.

### Main Applications
✅ Pharmaceutical Industry
Suppository substrate for rectal & vaginal suppositories, for local medication or systemic absorption; widely used for antipyretic, anti‑inflammatory, gynecological suppositories.
Also used as release regulator, lubricant for transdermal preparations and oral excipients.

✅ Cosmetics Industry
Softening and firming agent for lipstick, cream and lip balm; improve spreadability, bring moisturizing texture.

### Safety Notice
Non‑hazardous pharmaceutical excipient. Keep away from high temperature to avoid melting agglomeration.
