classification and labelling as sensitiser for benzenesulfonic acid,
di-C10-14-alkyl derivs., sodium salts (with a TBN of 2.8) is based on
the LLNA positive results. In addition, the sensitisation weight of
evidence for this category of sulfonates, is based on a series of
studies conducted according to the Modified Buehler design and on the
results of numerous skin sensitisation animal studies with low and high
TBN calcium sulfonates. Results of Human Repeat Insult Test (HRIPT) with
low and high TBN calcium sulfonates have also been considered (please
see attached file or refer to the respective section of the CSR). In
accordance with EU CLP Regulation (EC) No. 1272/2008, classification is
required for low TBN sodium sulfonates (TBN < 300) with a specific
concentration limit of 10% , and classification is not required for high
TBN sodium sulfonates (TBN ≥ 300).
