(14)C-Diethanolamine (7 mg/kg bw) was given orally to male Fischer 344 rats once or by daily repeat dosing for up to eight weeks. Single oral doses (0.7-200 mg/kg bw) were well absorbed but excreted very slowly. About 20-30% of oral and intravenous doses (7 mg/kg bw) was found in urine (mainly as unchanged diethanolamine), with less than 3% in feces and only 0.2% or less was exhaled (CO2) within 48 h. Most of the diethanolamine was retained in tissues at high concentrations. The tissue-to-blood ratios were 150-200 for the liver and kidney, 30-40 for the lung and spleen and 10-20 for the heart, brain and muscle. Tissue radioactivity was found mainly in aqueous extracts (up to 90%) and 5-10% was organic-extractable.

(14)C-Diethanolamine was applied to 19.5 sq cm of the dorsal skin (20 mg/sq cm, 1500 mg/kg bw) and covered for 48 hr (no washing) or for 6 hr before it was removed by washing. Absorbed (14)C-diethanolamine was determined in 48-hr urine and feces and from sampled tissues. Unwashed rats absorbed 1.4% and washed animals 0.64% of the dose, while the majority of (14)C-diethanolamine was recovered in the occlusive wrappings (80%) and in skin of the dose site (3.6%). The radioactivity was found in carcass, liver or kidneys but very little in urine (0.11%), feces or blood

Studies of the penetration of (14)C-diethanolamine from cosmetic formulations (shampoos hair dyes and body lotions) through human skin samples indicated that approximately 0.1% of the applied dose of shampoo and hair dye formulations was absorbed into the receptor fluid after 5-30 minutes; in a 72-hour repeated dose study with a body lotion formulation, nearly 30% of applied diethanolamine accumulated in the skin and approximately 1% was absorbed into the receptor fluid.

Dermal absorption of diethanolamine is suggested to occur in rats since N-nitrosodiethanolamine was excreted in the urine of male Sprague-Dawley rats which had been administered diethanolamine by dermal application and given nitrite in their drinking water.

Treatment of Wistar or Sherman rats with diethanolamine caused increases in the formation of hepatic phospholipids. In addition, dietary administration led to incorporation of ethanolamine into hepatic phospholipids, and repeated oral administration of diethanolamine in drinking water (one to three wk) at a dose of 320 mg/kg/day was found to reduce the level of incorporation of ethanolamine and choline into hepatic and renal phospholipids in Sprague-Dawley rats.

Diethanolamine is known to be incorporated into membrane phospholipids. It can be O-phosphorylated and N-methylated to metabolites that are incorporated into polar head groups as aberrant membrane phospholipids (phosphoglyceride and sphingomyelin analogues) via the ethanolamine metabolic pathway.

After a single intravenous or oral administration of diethanolamine, rats predomnantly excreted the parent compound in the urine; after repeated oral administration, the parent compound was still the major product excreted in the urine but N-methylated metabolites were also detected. The parent compound also accounted for the majority of radioactivity extracted from the liver and brain of rats administered (14)C-diethanolamine; two minor metabolites identified in tissues were N-methyldiethanolamine and N,N-dimethyldiethanolamine.

Diethanolamine (DEA) is a widely used ingredient in many consumer products and in a number of industrial applications. It has been previously reported that dermal administration of DEA to mice diminished hepatic stores of choline and altered brain development in the fetus. The aim of this study was to use mouse neural precursor cells in vitro to assess the mechanism underlying the effects of DEA. Cells exposed to DEA treatment (3mM) proliferated less (by 5-bromo-2-deoxyuridine incorporation) at 48 hr (24% of control [CT]), and had increased apoptosis at 72 hr (308% of CT). Uptake of choline into cells was reduced by DEA treatment (to 52% of CT), resulting in diminished intracellular concentrations of choline and phosphocholine (55 and 12% of CT, respectively). When choline concentration in the growth medium was increased threefold (to 210 uM), the effects of DEA exposure on cell proliferation and apoptosis were prevented, however, intracellular phosphocholine concentrations remained low. In choline kinase assays, we observed that DEA can be phosphorylated to phospho-DEA at the expense of choline. Thus, the effects of DEA are likely mediated by inhibition of choline transport into neural precursor cells and by altered metabolism of choline. /This/ study/ suggests that prenatal exposure to DEA may have a detrimental effect on brain development.

Diethanolamine increased the incidence and multiplicity of liver tumors in the mouse following chronic exposure. Diethanolamine is known to inhibit cellular choline uptake. Since choline deficiency produces tumors in rodents, diethanolamine, through choline depletion, may result in tumor development in rodents. The potential for diethanolamine to function through this mode of action in humans is not known. The present studies examined the effect of diethanolamine (0-500 mug/mL) and choline depletion on DNA synthesis and changes in expression of genes involved in cell growth pathways in primary cultures of mouse, rat, and human hepatocytes. In mouse and rat hepatocytes DNA synthesis was increased following treatment with 10 mug/mL diethanolamine and higher (3- to 4-fold over control). In contrast, diethanolamine failed to increase DNA synthesis in human hepatocytes. Incubation of hepatocytes in medium containing reduced choline (1/10 to 1/100 of normal medium; 0.898 to 0.0898 mg/L vs. 8.98 mg/L) increased DNA synthesis (1.6- and 1.8-fold of control in mouse and rat hepatocytes, respectively); however, choline depletion did not induce DNA synthesis in human hepatocytes. Mouse and rat hepatocytes incubated in medium supplemented with 2- to 50-fold excess choline reduced diethanolamine-induced DNA synthesis to control levels or below. Gene expression analysis of mouse and rat hepatocytes following diethanolamine treatment showed increases in genes associated with cell growth and decreases in expression of genes involved in apoptotic pathways. These results support the hypothesis that choline depletion is central to the mode of action for the induction of rodent hepatic neoplasia by diethanolamine. Furthermore, since diethanolamine treatment or choline depletion failed to induce DNA synthesis in human hepatocytes, these results suggest that humans may not be at risk from the carcinogenic effects of diethanolamine.
