TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 10(SRC), determined from a structure estimation method(2), indicates that triglycidyl isocyanurate is expected to have very high mobility in soil(SRC). Volatilization of triglycidyl isocyanurate from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.2X10-9 atm-cu m/mole(SRC), derived from its vapor pressure, 5.25X10-5 mm Hg(3), and water solubility, 9500 mg/L(3). Triglycidyl isocyanurate is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(3). Utilizing the Japanese MITI test, 0% of the Theoretical BOD was reached in 4 weeks(4) indicating that biodegradation is not an important environmental fate process in soil(SRC).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 10(SRC), determined from a structure estimation method(2), indicates that triglycidyl isocyanurate is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 2.2X10-9 atm-cu m/mole(SRC), derived from its vapor pressure, 5.25X10-5 mm Hg(4), and water solubility, 9500 mg/L(4). According to a classification scheme(5), an estimated BCF of 3(SRC), from an estimated log Kow of 1.21(2) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Hydrolysis may be an environmental fate process due to the presence of epoxide rings(6). Epoxides hydrolyze rapidly at 298 K and pH7; conjugated and aromatic epoxides have half-lives of a few minutes(7). Utilizing the Japanese MITI test, 0% of the Theoretical BOD was reached in 4 weeks(8) indicating that biodegradation is not an important environmental fate process in water(SRC).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), triglycidyl isocyanurate, which has a vapor pressure of 5.25X10-5 mm Hg at 20 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase triglycidyl isocyanurate is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 21 hrs(SRC), calculated from its rate constant of 1.9X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(2). Particulate-phase triglycidyl isocyanurate may be removed from the air by wet and dry deposition(SRC). Triglycidyl isocyanurate contains chromophores that absorb at wavelengths >290 nm(3) and, therefore, may be susceptible to direct photolysis by sunlight(SRC).

Reproductive Toxin - A chemical that is toxic to the reproductive system, including defects in the progeny and injury to male or female reproductive function. Reproductive toxicity includes developmental effects. See Guidelines for Reproductive Toxicity Risk Assessment.

IDENTIFICATION AND USE: Triglycidyl isocyanurate (TGT) is a white solid. TGT is used as a crosslinking agent in polymer synthesis, additive in plastic, rubber, and adhesives, hardener in polyester powder coatings, in protective coatings of electronic devices, in top-coated and solder-resistant inks. HUMAN STUDIES: The reported health effects in humans are contact dermatitis and respiratory sensitization. It may also cause serious eye damage. TGT did not induce chromosomal aberrations in human lymphocytes at concentrations up to 2500 ng/mL. Only one aberration was reported at each of the two higher concentrations of 5000 and 10,000 ng/mL. Human trials were performed during clinical development of alpha-TGT as an antitumor agent. In these studies, alpha-TGT was administered iv to cancer patients at doses up to 900 mg/kg bw using a variety of dosing regimes. Toxic signs included myelosuppression, nausea and vomiting, and, rarely, alopecia and leucopenia at high doses (>600 mg/kg bw). Owing to its severe local toxicity (thrombophlebitis) at the site of injection, the use of alpha-TGT as an antitumor agent was not pursued. ANIMAL STUDIES: Acute animal toxicity studies reveal that TGT is toxic by oral and inhalation routes of exposure but has low acute dermal toxicity. TGT produces serious eye irritation. It is a skin sensitizer but not a skin irritant. Short-term repeated dose studies revealed renal, lung, gastric/duodenal, and sperm cell damage. In a subchronic toxicity/fertility study conducted in rats, a dose-dependent reduction in the number of spermatozoa was the only effect observed at concentrations of up to 100 ppm TGT in the diet. The chemical has produced positive results in a range of in vitro genotoxicity studies (gene mutation in bacterial and mammalian cells, unscheduled DNA synthesis, sister chromatid exchanges, and chromosomal aberration assays). Genotoxic effects have also been observed in vivo in somatic (bone marrow) cells and germ cells in the testes. Genotoxicity studies have revealed that the inhalation of TGT produces cytotoxicity and chromosomal aberrations in mouse spermatogonia. A 13-week dietary study in rats has indicated no effects on male fertility.

/HUMAN EXPOSURE STUDIES/ alpha-1,3,5-Triglycidyl-s-triazinetrione (TGT) is a triepoxide derivative with alkylating properties discovered by random screening. TGT has been found to be active against a wide variety of murine tumors, including a P388 subline resistant to cyclophosphamide. The starting dose in this phase-I study was 30 mg/sq m as a single dose IV, repeated every 3-4 weeks, increasing up to 2,700 mg/sq m. Severe dose-limiting toxicity took the form of phlebitis becoming apparent a few days after treatment. This was initially seen at the 480 mg/sq m dose level, and was observed with increasing frequency and intensity at higher dose levels. Leukopenia occurred regularly at dose levels above 1,800 mg/sq m and resulted in life-threatening leukopenia in one patient, and in a toxic death at 2,700 mg/sq m in another patient. Other toxic side-effects included moderate reversible thrombocytopenia, nausea, and vomiting. ...

The only available human data are from clinical trials with alpha-triglycidyl isocyanurate (intravenous administration), which indicate that alpha-triglycidyl isocyanurate has a mean half-life in the blood of approximately 1 min ... .

In an oral (gavage) study in mice, ... blood plasma analysis indicated that triglycidyl isocyanurate was metabolized by hydrolysis to the diol diepoxide, the bis-diol epoxide, and the fully hydrolysed tris-diol, with no free triglycidyl isocyanurate detected 8 hr after treatment.

In in vitro studies, rapid hydrolysis of triglycidyl isocyanurate involving the enzyme epoxide hydrolase was observed in mouse liver preparations. Hydrolysis was also observed in rat liver preparations but not in rat lung preparations. Microsomal epoxide hydrolase activity with triglycidyl isocyanurate as substrate measured in two human livers obtained from kidney donors was found to be greater than the activity in rat liver.

... Metabolism of TGIC involves hydrolysis of the epoxy functions, leading to the formation of the trisdiol derivative, and is promoted by hepatic but not pulmonary epoxide hydrolase. Non-enzymatic hydrolysis of the epoxy functions occurs under conditions of low pH. Further mechanisms for the metabolism of TGIC have not been investigated. Excretion of TGIC and/or its metabolites is largely via the urine. Urinary metabolites of TGIC have not been identified.

In an oral (gavage) study in mice, at least 17% of the administered dose was absorbed within 24 hr, with blood analysis indicating that the absorption of triglycidyl isocyanurate administered in aqueous solution was twice that of triglycidyl isocyanurate in sesame oil.

... In the manufacture of powder coatings, triglycidyl isocyanurate granules are mixed with other ingredients; the mix is then melted and extruded as a brittle sheet, chipped, and packaged. Generally, the particle size of 90-95% of the powder coating is >10 um. Powder coatings usually contain 4-10% triglycidyl isocyanurate and are sprayed onto metal objects by an electrostatic process. The coated metal objects are then treated in an oven to a temperature of about 200 °C. This heating causes the powder coatings to melt, flow, and chemically cross-link. The coatings are durable and resist ultraviolet damage; as a result, they are typically used in outdoor applications. Triglycidyl isocyanurate is also used in solder "mask" inks in the printed circuit board industry. The two-part inks contain approximately 60% triglycidyl isocyanurate in the hardener component. The inks are applied by curtain coating, electrostatic spraying, or screen printing. The coated circuit board is finally passed through an oven at 150 °C to complete the curing.
