Applicant's summary and conclusion
- Conclusions:
- NOAEL was considered to be 1000 mg/kg bw for P and F1 generation when male and female rats were treated with 2-Naphthalenecarboxylic acid, 3-hydroxy-4-[(4- methyl-2- sulfophenyl)azo]-,calcium salt orally by gavage 56 Days.
- Executive summary:
In a Combined Repeated Dose and Reproductive/Developmental Toxicity Screenin g Test,male and female rats treated with 2-Naphthalenecarboxylic acid, 3-hydroxy-4-[(4- methyl-2- sulfophenyl)azo]-,calcium saltin the concentration of 0, 100, 300 and 1000 mg/kg orally by gavage 56 Days.No effect on mating performance, duration of gestation and sex distribution were observed in treated rats. In addition,No effect on pup viability,body weight and gross anomalies were observed.Therefore, NOAEL was considered to be 1000 mg/kg bw for P and F1 generation whenmale and female rats were treated with2-Naphthalenecarboxylic acid, 3-hydroxy-4-[(4- methyl-2- sulfophenyl)azo]-,calcium saltorally by gavage 56 Days.
