Executive summary:

Guinea pig maximization test was conducted for chemical 1,1'-biphenyl (CAS no.: 92 -52 -4, E.C. no. 202 -163 -5) to assess its skin sensitization potential in accordance with OECD Guideline 406. Since the chemical did not induce any signs of contact sensitization, the test chemical was considered to be not sensitizing to the guinea pigs’ skin.

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not sensitising)

Additional information:

Skin sensitization:

1. Guinea pig maximization test was conducted for chemical1,1'-biphenyl (CAS no.: 92 -52 -4, E.C. no. 202 -163 -5)to assess its skin sensitization potential in accordance with OECD Guideline 406. Since the chemical did not induce any signs of contact sensitization, the test chemical was considered to be not sensitizing to the guinea pigs’ skin.

2. Skin sensitizing test was conducted forNicotinonitrile (CAS no.: 100 -54 -9, E.C. no.: 202 -863 -0)in rabbit. Allergic effect was not observed in any of the animals. Hence the test substance was considered to be non sensitizing to rabbit skin.

Justification for classification or non-classification

Based on the studies available and weight of evidence the test substance was considered to be non-sensitizing.
