1/ Introduction
Triethyl citrate is an ester of citric acid and ethanol, widely used in pharmaceutical formulations. It functions as a plasticizer in film coatings, improving flexibility, durability, and preventing cracking of the film. Moreover, triethyl citrate is considered safe, non-toxic, and compatible with various coating polymers.
2/ Key Advantages
- High safety profile — non-toxic, non-irritating, and readily metabolized in the body.
- Compatible with a wide range of film-coating polymers.
- Excellent oxidative stability — resistant to degradation over time, thereby enhancing product shelf life and stability.
- Slow evaporation rate, helping maintain film plasticity throughout spraying and drying processes.
- Low viscosity and good dispersibility in water.
- Product complies with USP/EP/BP
- The manufacturer has EXCIPACT GMP Certificate for Pharma application
- Stock available at GSP/ GDP warehouse, prompt delivery, competitive price
3/ Applications
- Plasticizer in film coating: lowers the glass transition temperature, making the film more flexible, soft, and elastic; reduces the risk of cracking and enhances adhesion to the tablet core.
- Solvent/carrier in liquid formulations: dissolves poorly water-soluble drugs and excipients, and is used in microemulsion systems.
