Description of key information
Data available for the structurally similar read across chemicals has been reviewed to determine the acute oral toxicity of the test chemical 2,2'-[(3,3'-dimethyl[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[4-nonylphenol] / C.I. Solvent Yellow 107 (67990-27-6).The studies are as mentioned below:
1.In a acute oral toxicity study,rats were treated with test chemical in the concentration of 5000 mg/kg bw orally. No mortality observed in treated rats at 5000 mg/kg bw. Therefore,LD50 was considered to be > 5000 mg/kg bw,when rats were treated with test chemical orally.
2.Acute oral toxicity study was done in rats using test material Barium bis[2-chloro-5-[(2-hydroxy-1-naphthyl)azo]toluene-4-sulphonate] (5160-02-1).No mortality was observed at dose 10000 mg/kg bw in treated rats.Hence,LD50 value was considered to be >10000 mg/kg bw,when rats were treated with Barium bis[2-chloro-5-[(2-hydroxy-1-naphthyl)azo]toluene-4-sulphonate] (5160-02-1)orally.
3.Acute oral toxicity study was performed in rats using test chemical.No mortality was observed at dose10000 mg/kg bw.In clinical sign observations, changes on urine composition,behavioral somnolence (general depressed activity) and dermatitis were observed.Hence,LD50 value was considered to be >10000 mg/kg bw,when rats were treated with test chemical orally.
Thus, based on the above summarised studies,2,2'-[(3,3'-dimethyl[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[4-nonylphenol] / C.I. Solvent Yellow 107 (67990-27-6) and it’s structurally similar read across substance, it can be concluded that LD50 value is greater than 2000 mg/kg bw. Thus, comparing this value with the criteria of CLP regulation,2,2'-[(3,3'-dimethyl[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[4-nonylphenol] / C.I. Solvent Yellow 107 (67990-27-6)cannot be classified for acute oral toxicity.Hence, based on the data available for the structurally similar read across, test chemical 2,2'-[(3,3'-dimethyl[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[4-nonylphenol] / C.I. Solvent Yellow 107 (67990-27-6)is not likely to be toxic at the dose of 10000 mg/kg bw.
