大约40%的己二醇出现在尿液中,但其中只有4%是以自由醇的形式排出;另外36%与葡糖醛酸结合。
It was also shown that approximately 40% of the hexylene glycol was accounted for in the urine, but only 4% of the amount excreted was free glycol; the other 36% was conjugated with glycuronic acid.
IDENTIFICATION AND USE: Hexylene glycol is a colorless liquid used as a chemical intermediate, a selective solvent in petroleum refining, a component of hydraulic fluids, a solvent for inks, a cement additive, and in cosmetics. HUMAN EXPOSURE AND TOXICITY: Five human subjects given oral doses of 37 g of hexylene glycol daily for 24 days (estimated daily dosage 14-28 mg/kg body weight) reported no subjective symptoms that could be attributed to the intake of hexylene glycol; no alterations in urine parameters were detected. In another study, most subjects exposed for 15 min to 50 ppm of hexylene glycol in the air were able to detect the odor and a few noted eye irritation. At a concentration of 100 ppm, the odor was plain and some noted nasal irritation and respiratory discomfort. At 1000 ppm (4840 mg/cu m), there was irritation of the eyes, nose, and throat, and respiratory discomfort. Additionally, a case of severe contact urticaria with systemic involvement resembling an anaphylactic reaction, following the application of a topical corticosteroid formulated with hexylene glycol as an excipient has been reported. Swelling and redness were seen in 23 out of 823 eczema patients who were treated with a 30% or 50% aqueous solution in a 48-hr covered patch test. ANIMAL TOXICITY STUDIES: The clinical signs observed in animals acutely intoxicated with hexylene glycol are predominately of central nervous system (CNS) depression and include decreased activity, muscle incoordination and flaccidity, palpebral closure, piloerection, narcosis and anesthesia. Mice were fed hexylene glycol orally 20 mg/day in 2 mL of whole milk for up to 81 days and only minor effects were found in the kidneys of a few animals. None of the rats that were fed hexylene glycol in milk for 4 months at the average rate of 98 and 150 mg/day showed adverse effects in growth nor were there histopathologic changes in the liver and testes, but there were minor changes in the kidneys. It was also shown that approximately 40% of the hexylene glycol was accounted for in the urine, but only 4% of the amount excreted was free glycol; the other 36% was conjugated with glycuronic acid. In another study, hexylene glycol was administered by oral gavage for 90 days to Sprague Dawley rats at dose levels of 50, 150 and 450 mg/kg/day. This study included a functional observational battery (FOB), which gave no evidence of neurotoxic effects. Hepatocellular hypertrophy coupled with increased liver weight was observed at 450 mg/kg/day in both sexes and in males only at 150 mg/kg/day. In the absence of degenerative or necrotic change this was considered an adaptive response to increased metabolic demand. At 150 and 450 mg/kg/day kidney histopathology (higher incidence and severity of acidophilic globules in the tubular epithelium) and increased kidney weights observed in male rats only are suggestive of male rat specific alpha-2-microglobulin nephropathy, which was subsequently confirmed. There were no adverse effects on other organs including the reproductive organs. The fertility of male rats given an average oral dose of 148 to 190 mg/day of hexylene glycol for 130 days was unchanged when compared to that of the control group. Developmental study in rats found increased pup mortality and reduced body weight gain at 1000 mg/kg/day. Hexylene glycol produced negative Ames test results for Salmonella Typhimurium TA 1535, TA 1537, TA 1538, TA 98, TA 100 with and without activation. ECOTOXICITY STUDIES: Aquatic toxicity was evaluated in the sea urchin embryo (Arbacia punctulata) by the inhibition of tritiated thymidine incorporation after a brief exposure to toxic chemicals. In preliminary trials, using compounds including hexylene glycol, results accurately predicted reduced survival and morphological delay after 48 hr exposures.
