Description
Triethyl Citrate Product Overview
Triethyl citrate (C12H20O7) is a clear, colorless to pale yellow, almost odorless liquid that mixes with alcohols and dissolves partly in water. Because producers make it from citric acid and ethanol, it is a bio-based, phthalate-free plasticizer.
Pharmaceutical companies use it as the standard plasticizer in film coatings, especially for enteric and sustained-release coatings based on methacrylate copolymers and ethylcellulose. Similarly, food producers use it as a foam stabilizer for dried egg white and as a carrier for flavors (E1505). Cosmetic formulators also use it in deodorants, because it inhibits the enzymes that cause odor, and in nail polish.
In addition, polymer producers use it as a plasticizer for cellulose acetate and other polymers that need a non-toxic, phthalate-free alternative. Related raw materials in our range also include Citric Acid Anhydrous and Ethanol.

Frequently Asked Questions
Why is triethyl citrate used in enteric coatings?
Because it makes methacrylate and cellulose films flexible, coatings do not crack and protect the tablet core in the stomach.
Is triethyl citrate phthalate-free?
Yes. It comes from citric acid and ethanol, so it serves as a phthalate-free plasticizer.
How can I get a price and documents?
Prices depend on quantity, packaging and destination, so please contact us with your required volume. We then send a quotation together with the CoA and SDS.
