| 건강 유해성 | Excerpt from NIOSH Pocket Guide for 4-Dimethylaminoazobenzene: |
| 유해성 요약 | 4-Dimethylaminoazobenzene is used as a dye for coloring polishes, wax products, and soap. Acute (short- term) dermal exposure to 4-dimethylaminoazobenzene may result in contact dermatitis in humans. No information is available on the chronic (long-term), reproductive, developmental, or carcinogenic effects of 4-dimethylaminoazobenzene in humans. Animal studies have reported birth defects in the offspring of mice exposed to 4-dimethylaminoazobenzene and tumors of the lung, liver, and bladder from oral exposure to 4-dimethylaminoazobenzene. EPA has not classified 4-dimethylaminoazobenzene for carcinogenicity. The International Agency for Research on Cancer (IARC) has classified 4- dimethylaminoazobenzene as a Group 2B, possibly carcinogenic to humans.In animal studies: liver injuryIn feeding studies of dogs: bladder cancer[HSDB] |
