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 Profile

Moderately toxic by intraperitoneal route. Mildly toxic by ingestion and inhalation. Combustible liquid when exposed to heat or flame. To fight fire, use dry chemical, CO2. When heated to decomposition it emits acrid smoke and irritating fumes. See also ESTERS and CITRIC ACID.

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

저장
