2-phenylpropan-2-ol

Endpoint summary

Description of key information

Oral:  WoE: The available LD50s range from ± 1000 – 3000 mg/kg bw.

Inhalation: No valid studies are available. The available study gets a K4 since no original references are available only secondary references. No LD50 is available, no LD50 available, data is not sufficient for C&L purposes.

This substance is a transported isolated intermediate and therefore no additional testing is warranted.

Dermal: No valid studies are available. The available study gets a K4 since no original references are available only secondary references. The available LD50 is 4300 mg/kg bw. Since only one secondary reference is available the data is not sufficient for C&L purposes.

This substance is a transported isolated intermediate and therefore no additional testing is warranted.

Acute oral	WoE Since no original references are available only secondary references all available data is K4. The available LD50s range from ± 1000 – 3000 mg/kg bw. Since most of the values are < 2000 mg/kg the substance is classified for acute oral toxicity: Acute oral Category 4.   Classification and Labeling Acute oral Category 4.
LD50 rat: 1300 mg/kg (1000-1700 mg/kg)     The acute oral LD50 for 2-phenyl-2-propanol in rats was reported to be 1.3 g/kg (1.0–1.7 g/kg). Rats (10/dose) were dosed by orally at doses of 0.6, 0.85, 1.22, 1.73, 2.47, and 5.0 g/kg. Mortalities were 0, 3, 4, 6, 10, and 10 with increasing does; all animals died within 2 days of dosing. Clinical observations included lethargy, ataxia, loss of righting reflex, and coma. Necropsy observations included oral and nasal excretions, redness, yellowing and bloating in the intestines, red areas in stomach, dark lungs, and dark and/or mottled kidneys,	Moreno. O. M. (1977).

Additional information

Justification for selection of acute toxicity – oral endpoint

Since no original references are available only secondary references all available data is K4.

The available LD50s range from ± 1000 – 3000 mg/kg bw. Since most of the values are < 2000 mg/kg the substance is classified for acute oral toxicity: Acute oral Category 4.

Justification for classification or non-classification

Acute oral: Since no original references are available only secondary references all available data is K4.

The available LD50s range from ± 1000 – 3000 mg/kg bw. Since most of the values are < 2000 mg/kg the substance is classified for acute oral toxicity: Acute oral Category 4.

Acute inhalation: No LD50 available, data is not sufficient for C&L purposes.

Acute dermal: Since only one secondary reference is available the data is not sufficient for C&L purposes.
