/EXPTL THER/ Structure-activity studies with nine glycol alkyl ethers were conducted with a cellular leukemia transplant model in male Fischer rats to measure the effects on neoplastic progression in transplant recipients. Chemicals were given ad libitum in the drinking water simultaneously with the transplants and continued throughout the study. In all, 20 million leukemic cells were injected sc into syngeneic rats, which after 60 days resulted in a 10-fold increase in relative spleen weights, a 100-fold increase in white blood cell counts, and a 50% reduction in red blood cell indices and platelet counts. Ethylene glycol monomethyl ether given at a dose of 2.5 mg/mL in the drinking water completely eliminated all clinical, morphological, and histopathological evidence of leukemia, whereas the same dose of ethylene glycol monoethyl ether reduced these responses by about 50%. Seven of the glycol ethers were ineffective as anti-leukemic agents, including ethylene glycol, the monopropyl, monobutyl, and monophenyl ethylene glycol ethers, diethylene glycol, and the monomethyl and monoethyl diethylene glycol ethers. Ethylene glycol monomethyl ether more than doubled the latency period of leukemia expression and extended survival for at least 210 days. A minimal effective dose for a 50% reduction in the leukemic responses was 0.25 mg/mL ethylene glycol monomethyl ether in the drinking water (15 mg/kg body weight), whereas a 10-fold higher dose of 2-ethylene glycol monoethyl ether was required for equivalent antileukemic activity. In addition, the in vitro exposure of a leukemic spleen mononuclear cell culture to ethylene glycol monomethyl ether caused a dose- and time-dependent reduction in the number of leukemia cells after a single exposure to 1-100 mM concentrations, whereas the ethylene glycol monomethyl ether metabolite, 2-methoxyacetic acid, was only half as effective.

Butyl carbitol can be absorbed through skin, but only in toxic amt if application is prolonged & continuous.

In vitro percutaneous absorption studies were carried out for ... /tritiated water, 2-ethoxyethyl acetate, diethylene glycol monobutyl ether, urea, di(2-ethylhexyl) phthalate, 2-ethylhexanol, ethyl 3-ethoxypropionate, and 2-propoxyethanol/ using full thickness rat skin and human stratum corneum. The purpose of the studies was to compare the rates of absorption for the two species. For each of the chemicals, the observed rate using full thickness rat skin was greater than that observed for human stratum corneum. The ratios of the rates (rat/human) varied from 1.7 to 5.8 with a mean value of 3.1. ... It was concluded that rat skin was more permeable than human skin for each of these eight chemicals. ...

Male and female Sprague-Dawley rats received 200 and 2000 mg neat (14)C-DEGBE/kg bw and 200 mg of a 10% aqueous solution/kg bw. Dermal adsorption rate was 0.73 and 1.46 mg/sq cm/hr for males and females respectively.

To assist the evaluation of the hazards of skin contact with selected undiluted glycol ethers, their absorption across isolated human abdominal epidermis was measured in vitro. Epidermal membranes were set up in glass diffusion cells and, following an initial determination of permeability to tritiated water, excess undiluted glycol ether was applied to the outer surface for 8 hr. The appearance of glycol ether in an aqueous "receptor" phase bathing the underside of the epidermis was quantified by a gas chromatographic technique. A final determination of tritiated water permeability was compared with initial values to establish any irreversible alterations in epidermal barrier function induced by contact with the glycol ethers. 2-Methoxyethanol was most readily absorbed (mean steady rate 2.82 mg/sq cm/hr), and a relatively high absorption rate (1.17 mg/sq cm/hr) was also apparent for 1-methoxypropan-2-ol. There was a trend of reducing absorption rate with increasing molecular weight or reducing volatility for monoethylene glycol ethers (2-methoxyethanol, 2.82 mg/sq cm/hr; 2-ethoxyethanol, 0.796 mg/sq cm/hr; 2-butoxyethanol, 0.198 mg/sq cm/hr) and also within the diethylene glycol series: 2-(2-methoxyethoxy) ethanol (0.206 mg/sq cm/hr); 2-(2-ethoxyethoxy) ethanol (0.125 mg/sq cm/hr) and 2-(2-butoxyethoxy) ethanol (0.05 mg/sq cm/hr). The rate of absorption of 2-ethoxyethyl acetate was similar to that of the parent alcohol, 2-ethoxyethanol. Absorption rates of diethylene glycol ethers were slower than their corresponding monoethylene glycol equivalents. Combination of intrinsic toxicity and ability to pass across skin contribute to assessment of hazards of contact with undiluted glycol ethers.

Male and female Sprague-Dawley rats received 200 and 2000 mg neat (14)C-DEGBE/kg bw and 200 mg of a 10% aqueous solution/kg bw. 2-(2-butoxyethanol)acetic acid was the major urinary metabolite identified and the glucuronide conjugate was present at levels of 5.2% to 8.2% of the urinary (14)C.

The metabolism of diethylene glycol monobutyl ether acetate was studied in vitro and in vivo in male Sprague-Dawley rats. The extent of conversion of diethylene glycol monobutyl ether acetate to diethylene glycol monobutyl ether was determined. In vitro, diethylene glycol monobutyl ether acetate was rapidly hydrolyzed by rat blood to diethylene glycol monobutyl ether; the biological half-life was less than 3 min. The urine was the major pathway for eliminating diethylene glycol monobutyl ether acetate derived (14)C activity; 80% was eliminated after 24 hr. Only 2 to 3% of each dose was eliminated in the feces. About 5% of each dose was eliminated in the expired air, mostly as radioactive carbon dioxide. Only 1-3% doses were found in the tissues and ied. No unchanged diethylene glycol monobutyl ether acetate or diethylene glycol monobutyl ether or 2-butoxyacetic acid, a putative hematotoxic diethylene glycol monobutyl ether acetate metabolite, was found. Diethylene glycol monobutyl ether acetate is rapidly hydrolyzed to diethylene glycol monobutyl ether by rat blood. The biological effects of diethylene glycol monobutyl ether acetate and diethylene glycol monobutyl ether would be indistinguishable. No 2-butoxyacetic acid is produced.

In the present study, floor lacquerers' (n = 22) inhalation and total exposure to 2-(2-alkoxy)ethoxyethanols was measured. The measurements of inhalation exposure were done with charcoal tubes, and total exposure was biomonitored by urinalysis of 2-(2-alkoxyethoxy)acetic acids. The 8hr inhalation exposures of floor lacquerers to 2-(2-methoxyethoxy)ethanol (DEGME), 2-(2-ethoxyethoxy)ethanol (DEGEE) and 2-(2-butoxyethoxy)ethanol (DEGBE) were in average 0.23 +/- 0.07 ppm (average+/-S.D., n = 3), 0.08 +/- 0.07 ppm (n = 16), and 0.05 +/- 0.03 ppm (n = 16), respectively. The excretions of 2-(2-methoxyethoxy)acetic acid (MEAA), 2-(2-ethoxyethoxy)acetic acid (EEAA) and 2-(2-butoxyethoxy)acetic acid (BEAA) were in average 4.9 +/- 4.3 mmol/mol creatinine, 9.3 +/- 8.0 mmol/mol creatinine and 9.2 +/- 7.4 mmol/mol creatinine, respectively. A linear relationship was found between the urinary 2-(2-alkoxyethoxy)acetic acid concentrations and the preceding 8-hr occupational exposure to 2-(2-alkoxyethoxy)ethanol. /2-(2-Alkoxyethoxy)ethanol/
