| Hazard Information | Back Directory | [Chemical Properties]
Acetyl tributyl citrate (ATBC) is a colorless, odorless liquid. Its water solubility is less than 0.002 g/100 mL, but it is soluble in organic solvents. | [Chemical Properties]
Acetyltributyl citrate is a clear, odorless, practically colorless, oily
liquid. | [Chemical Properties]
clear colorless liquid | [Chemical Properties]
Tributyl acetylcitrate has a very faint, sweet, herbaceous odor. At high levels (e.g., 1000 ppm emulsion in water), it has
a mild, fruity, nondescript flavor. | [Uses]
Labelled Tributyl O-Acetylcitrate (T772950). Topical pharmaceutical formulation anesthetic surfactant ester. | [Uses]
plasticizer flavoring agent | [Preparation]
From citric acid via the tributyl ester followed by acetylation. | [Production Methods]
Acetyltributyl citrate is prepared by the esterification of citric acid
with butanol followed by acylation with acetic anhydride. | [Taste threshold values]
An emulsion of the title material in water at 1000 ppm has only a very faint, mildly fruity-winey, berry-like odor and a mild, nondescript taste.
| [General Description]
Tributyl 2-acetylcitrate is a hydrophobic biodegradable plasticizer, that is usually synthesized by esterification of citric acid. Pharmaceutically, it is used as an excipient, which is generally applied as a thin film over the tablets or capsules.
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. | [Pharmaceutical Applications]
Acetyltributyl citrate is used to plasticize polymers in formulated
pharmaceutical coatings, including capsules, tablets, beads, and
granules for taste masking, immediate release, sustained-release
and enteric formulations. | [Safety]
and films intended for direct food contact. It is also used in selfadhesive
thin films used for topical delivery systems. It is generally
regarded as a relatively nontoxic and nonirritating material.
However, ingestion of large quantities may be harmful.
LD50 (cat, oral): >50 mL/kg
LD50 (mouse, IP): >4 g/kg
LD50 (rat, oral): >31.5 g/kg | [Carcinogenicity]
The chronic toxicity of ATBC
was evaluated in rats fed diets containing 200, 2000, or
20,000 ppm of ATBC for 2 years. There were no treatment-
related lesions in any organs examined. | [Solubility in organics]
Miscible with alcohol and oils.
| [storage]
Acetyltributyl citrate should be stored in a well-closed container in a
cool, dry location at temperatures not exceeding 38℃. When stored
in accordance with these conditions, acetyltributyl citrate is a stable
product. | [Incompatibilities]
Acetyltributyl citrate is incompatible with strong alkalis and
oxidizing materials. | [Regulatory Status]
Included in FDA Inactive Ingredients Database (oral capsules and
tablets). Included in nonparenteral medicines licensed in the UK.
Approved in the USA for direct food contact in food films. |
