P405
P501
[Rationale for the Classification]
Based on (1) and (2), it was classified in Category 1B. The classification result was changed by considering the revision of the GHS classification guidance for the Japanese Government and the results in experimental animals.

[Evidence Data]
(1) As for classification results by domestic and international organizations, it was classified as R by NTP (NTP RoC (14th, 2016)), as B2 by EPA (IRIS (1989)) and in Carc.1B in EU CLP (EU CLP classification (Access on October 2019)). In addition, IARC concluded that there is sufficient evidence in experimental animals for the carcinogenicity of this substance (Michael's base) (IARC 99 (2010)).
(2) On administration by feeding of this substance, increased incidences of follicular cell carcinomas of the thyroid in rats of both sexes, and increased incidences of a combination of benign hepatocellular adenomas and malignant hepatocellular carcinomas in mice of both sexes, were noted (NTP TR186 (1979)).

[Reference Data, etc.]
(2) In a 4-week repeated dose toxicity test with rats dosed by feeding, reduced body weight gain in males at or above 315 ppm (converted guidance value: 4.9 mg/kg/day, within the range of Category 1), reduced body weight gain in females at or above 680 ppm (converted guidance value: 10.6 mg/kg/day, within the range of Category 2), and rough hair and arched backs in females at 3,155 ppm (converted guidance value: 49 mg/kg/day, within the range of Category 2) were observed (NTP TR186 (1979), DFGOT vol.1 (1991)).
(3) In a 78-week repeated dose toxicity test with mice dosed by feeding, at or above 1,250 ppm (converted guidance value: 187.5 mg/kg/day, exceeding Category 2), increased incidences of papillary and focal hyperplasia in the thyroid were observed (NTP TR186 (1979), DFGOT vol.1 (1991)).
