Three male and three female Wistar rats received single oral doses of 50 mg /tributylamine/ test substance per kg body weight. Excretion and metabolism of the test substance were investigated. After dosing, radioactivity was mainly excreted in urine. The unchanged test substance and the identified urinary metabolites accounted for 60-67% of the total excreted radioactivity in urine. The identified metabolites were the monohydroxy derivative (males: 19%, females: 29%), one dihydroxy derivative (males: 21%, females: 16%) and one monohydroxydesbutyl derivative (males: 14%, females: 9%). The unidentified metabolites are possibly trihydroxylated and di-desbutylated metabolism products.
IDENTIFICATION AND USE: Tributylamine is a pale yellow liquid. It is used as a solvent; inhibitor in hydraulic fluids; chemical intermediate. HUMAN EXPOSURE AND TOXICITY: A corrosive irritant to skin, eyes, and mucous membranes. 8 female and 8 male volunteers were exposed to tributylamine in varying concentrations. An odor threshold of 0.07 +/- 0.03 ppm (approx. 0.54 mg/cu m) was identified in this study. ANIMAL STUDIES: 6 albino rabbits, tested on 2 sites (1 site abraded, 1 site intact skin), 4 hr exposure, observation after 4, 24, 72 hr, Draize method used for scoring, erythema/eschar formation and for edema formation. Some thickening of the skin after 24 hr, exfoliation of epidermis after 5 d, skin appeared normal after 10 d. Six albino rabbits were subjected to test irritation of the eye. They were exposed to tributylamine into their conjunctival sac. After the exposure all animals showed slight conjuctival congestion, which was reversible within 2 to 3 hours. Exposure of four male and four female rats to 120 ppm for nineteen 6 hr exposures caused nose irritation, restlessness, incoordination, and tremors, organs appeared normal at autopsy. When rats were treated orally with 0.45 or 4.5 mg/kg bw/day daily for 6 months, there were no effects with respect to general constitution, behavior or histology. Pregnant rats were orally treated by gavage on gestation days 6 -15 with doses of 15, 45 and 135 mg/kg/day. Three dams died prematurely on days 7 and 8. The other animals of this group showed transient reductions in food consumption and body weight gain. There were no embryo- or fetotoxic effects except a slight and dose-related increase in fetal body weight gain, which was significant at the highest dose. The treatment did not produce malformations. Tributylamine did not induce micronuclei in vivo in mice.

Three male and three female Wistar rats received single oral doses of 50 mg radiolabelled /tributylamine/ per kg body weight. Excretion and metabolism of the test substance were investigated. After dosing, radioactivity was mainly excreted in urine. The unchanged test substance and the identified urinary metabolites accounted for 60-67% of the total excreted radioactivity in urine. The identified metabolites were the monohydroxy derivative (males: 19%, females: 29%), one dihydroxy derivative (males: 21%, females: 16%) and one monohydroxydesbutyl derivative (males: 14%, females: 9%).
