[Description]

Triethyl citrate is the triester of citric acid and ethyl alcohol.
Triethyl citrate is used as a flavoring agent in foods, as a high boiling solvent and plasticizer for vinyl resins and cellulose acetates, as a plasticizer in the pharmaceutical industry for coating. Triethyl citrate is used as a natural active ingredient and flavor component with excellent deodorizing and skin care properties in cosmetic and personal care products. Triethyl citrate is also used as a plasticizer and humectant for cigarette filters. Furthermore, triethyl citrate is used s a food additive for stabilizing foams, specifically as a whipping enhancer for organic egg whites during processing.

[General Description]

Triethyl citrate is a safe direct food additive.
[Pharmaceutical Applications]

Triethyl citrate and the related esters acetyltriethyl citrate, tributyl citrate, and acetyltributyl citrate are used to plasticize polymers in formulated pharmaceutical coatings. The coating applications include capsules, tablets, beads, and granules for taste masking, immediate release, sustained-release, and enteric formulations.
Triethyl citrate is also used as a direct food additive for flavoring, for solvency, and as a surface active agent.
[Safety]

Triethyl citrate is used in oral pharmaceutical formulations and as a direct food additive. It is generally regarded as a nontoxic and nonirritant material. However, ingestion of large quantities may be harmful.
LD50 (mouse, IP): 1.75 g/kg
LD50 (rat, IP): 4 g/kg
LD50 (rat, oral): 5.9 g/kg
LD50 (rat, SC): 6.6 g/kg
[storage]

Triethyl citrate should be stored in a closed container in a cool, dry location. When stored in accordance with these conditions, triethyl citrate is a stable product.
[Incompatibilities]

Triethyl citrate is incompatible with strong alkalis and oxidizing materials.
