Toxicity Profile |
---|
Route of Exposure | Oral (7) ; inhalation (7) ; dermal (7) |
---|
Mechanism of Toxicity | Though the mechanism of toxicity of 1,4-dioxane has not yet been elucidated, it is known that its carcinogenic effects are caused by a non-genotoxic mechanism that is most likely cytotoxic in nature. (7, 9) |
---|
Metabolism | Exposure to 1,4-dioxane may occur by inhalation, ingestion, and to a lesser extent by dermal contact. 1,4-Dioxane is quickly absorbed and metabolized to beta-hydroxyethoxyacetic acid (HEAA) by mixed-function oxidase enzymes. HEAA can then be converted to 1,4-dioxane-2-one under acidic conditions. Both of these products are rapidly and extensively eliminated in the urine (>95%). Unchanged 1,4-dioxane can also be excreted in the urine and in exhaled air, but mainly after high-dose exposure. (7) |

Toxicity Values | LD50: 1550 mg/kg (Intravenous, Rabbit) (1)
LD50: 4350 mg/kg (Subcutaneous, Mouse) (1)
LD50: >8300 mg/kg (Dermal, Rabbit) (1)
LD50: 2100 mg/kg (Oral, Dog) (1)
LD50: 799 mg/kg (Intraperitoneal, Rat) (3)
LC50: 46 g/m3 over 2 hours (Inhalation, Rat) (1) |

Lethal Dose | 470 ppm for an adult human. (2) |
---|
Carcinogenicity (IARC Classification) | 2B, possibly carcinogenic to humans. (6) |
---|
Uses/Sources | 1,4-Dioxane is primarily used in solvent applications for the manufacturing sector; however, it is also found in fumigants and automotive coolant. 1,4-Dioxane is a byproduct of the ethoxylation process in cosmetics manufacturing, thus many products on the market today contain 1,4-dioxane in very small amounts. However, some cosmetics, detergents, and shampoos may contain 1,4-dioxane at levels higher than recommended by the FDA for other products. 1,4-Dioxane can also be found in tap water, so human exposure to 1,4-dioxane may also occur during activities such as showering, bathing, and laundering. (7, 8) |

Minimum Risk Level | Not Available |
---|
Health Effects | 1,4-Dioxane for short period of time cause eye and nose irritation at low levels, and severe kidney and liver effects and possibly death at very high levels. For long-term exposure, studies in animals have shown that breathing vapors of 1,4-dioxane, swallowing liquid 1,4-dioxane or contaminated drinking water, or having skin contact with liquid 1,4-dioxane affects mainly the liver and kidneys. Studies in workers did not indicate whether 1,4-dioxane causes cancer, but animal studies suggest that it is a probable human carcinogen. (7) |

Symptoms | 1,4-Dioxane causes eye and respiratory tract irritation. (8) |
