Description of key information
Repeated dose toxicity: Oral
Data available for the target chemicals was reviewed to determine the toxic nature of the test chemical Reaction mass of Reaction mass of Benzenamine, N,N-dimethyl- , molybdate, tungstate & phosphates(101357-72-2). The studies are as mentioned below:
In a repeated-dose toxicity study, 0, 31.25, 62.5, 125, 250 or 500 mg/kg/day of test chemical was administered to 10 male and 10 female B6C3F1 mice per dose via gavage 5 days/week for 90 days. No mortality was observed. Dose-related increases in splenomegaly, and extramedullary hematopoiesis and hemosiderosis of the spleen were observed in the mice when given greater than 31.25 mg/kg/day of test chemical . Splenomegaly was reported as minimal in 4/10 mice, and extramedullary hematopoiesis and hemosiderois were reported as mild in 1/10 mice.Compound-related effects were noted in the spleen, liver, and kidney of male and female mice. The incidence and/or severity of the lesions increased with increasing dose levels, where treatment-related effects were present in all groups of treated mice at doses greater than 31.25 mg/kg/day. Therefore the NOAEL was considered to be 31.25 mg/kg/day in B6C3F1 mice for 13 weeks by oral gavage.
In a 90 day oral toxicity study, rats were administered test chemical at doses: 0, 300, 1500 or 7500 ppm (0, 65, 319 or 1756 mg/kg/day for males and 0, 91, 467 or 2316 mg/kg/day for females) The NOAEL for test chemical was determined to be 65 mg/kg/day for males rat and 467 mg/kg/day for females rat. While LOAEL for 5-amino-4-chloro-2-phenyl-2,3-dihydropyridazin-3-one (Chloridazon) was 319 mg/kg/day for males based on decreased body weight and gain, decreased food consumption and increased liver weight and decreased cholesterol and triglycerides and 2316 mg/kg/day for females rat based on slight decrease in body weight and gain, decreased food consumption and possibly decreased cholesterol and triglycerides.
Based on the data available for the test chemical Reaction mass of Benzenamine, N,N-dimethyl- , molybdate, tungstate & phosphates(101357-72-2) is not likely to be toxic by oral route as per the criteria mentioned in CLP regulation.
Repeated inhalation study:
According to Annex IX of the REACH regulation, testing by the inhalation route is appropriate only if exposure of humans via inhalation is likely. Taking into account the particle size distribution of the substance the majority of the particles was found to be in the size of 150 micron to 75 micron which is much larger size range compared to the inhalable particulate matter. The study need not to be conducted because the melting point of the test chemical is above 300°C has very low vapour pressure, so the potential for the generation of inhalable vapours is very low. Also the normal conditions of use of this substance will not result in aerosols, particles or droplets of an inhalable size, Thus, exposure to inhalable dust, mist and vapour of the chemical Reaction mass of Benzenamine, N,N-dimethyl- , molybdate, tungstate & phosphates(101357-72-2) is highly unlikely. Therefore this study is considered for waiver.
Repeated dermal study;
The acute toxicity value for substance Reaction mass of Benzenamine, N,N-dimethyl- , molybdate, tungstate & phosphates(101357-72-2) (as provided in section 7.2.3) is in range of >2000mg/kg body weight. Also, given the use of the chemical; repeated exposure by the dermal route is unlikely since the use of gloves is common practice in industries. Thus, it is expected that Reaction mass of Benzenamine, N,N-dimethyl- , molybdate, tungstate & phosphates shall not exhibit 28 day repeated dose toxicity by the dermal route. In addition, there is no data available that suggests that Reaction mass of Benzenamine, N,N-dimethyl- , molybdate, tungstate & phosphates(101357-72-2) exhibit repeated dose toxicity by the dermal route. Hence this end point was considered for waiver.

Splenomegaly was reported as minimal in 4/10 mice, and extramedullary hematopoiesis and hemosiderois were reported as mild in 1/10 mice. Compound-related effects were noted in the spleen, liver, and kidney of male and female mice. The incidence and/or severity of the lesions increased with increasing dose levels, where treatment-related effects were present in all groups of treated mice at doses greater than 31.25 mg/kg/day. Therefore the NOAEL was considered to be 31.25 mg/kg/day in B6C3F1 mice for 13 weeks by oral gavage.
In a 90 day oral toxicity study, rats were administered test chemical at doses: 0, 300, 1500 or 7500 ppm (0, 65, 319 or 1756 mg/kg/day for males and 0, 91, 467 or 2316 mg/kg/day for females) The NOAEL for test chemical was determined to be 65 mg/kg/day for males rat and 467 mg/kg/day for females rat. While LOAEL for 5-amino-4-chloro-2-phenyl-2,3-dihydropyridazin-3-one (Chloridazon) was 319 mg/kg/day for males based on decreased body weight and gain, decreased food consumption and increased liver weight and decreased cholesterol and triglycerides and 2316 mg/kg/day for females rat based on slight decrease in body weight and gain, decreased food consumption and possibly decreased cholesterol and triglycerides.
Based on the data available for the test chemical Reaction mass of Benzenamine, N,N-dimethyl- , molybdate, tungstate & phosphates(101357-72-2) is not likely to be toxic by oral route as per the criteria mentioned in CLP regulation.

Therefore this study is considered for waiver.
Repeated dermal study;
The acute toxicity value for substance Reaction mass of Benzenamine, N,N-dimethyl- , molybdate, tungstate & phosphates(101357-72-2) (as provided in section 7.2.3) is in range of >2000mg/kg body weight. Also, given the use of the chemical; repeated exposure by the dermal route is unlikely since the use of gloves is common practice in industries.

Justification for classification or non-classification
Based on the observations made for test chemical chemicals, Reaction mass of Benzenamine, N,N-dimethyl- , molybdate, tungstate & phosphates(101357-72-2)does not exhibit toxic nature upon repeated exposure by oral, inhalation and dermal route of exposure and hence is not likely to classify as per the criteria mentioned in CLP regulation.
