A LLNA study according to OECD 429 and EC. B.42 guidelines was
performed. The SI values calculated for the substance concentrations 10,
25 and 50% were 1.0, 1.4 and 1.1 respectively. Since there was no
indication that the test substance elicits an SI ≥ 3 when tested up to
50%, Silicic acid (H2Si2O5), barium salt (1:1), lead-doped was
considered not to be a skin sensitizer in the LLNA. It was established
that the EC3 value (the estimated test substance concentration that will
give a SI =3) (if any) exceeds 50%.
Based on these available data, Silicic acid(H2Si2O5), barium salt(1:1),
lead-doped does not have to be classified for skin sensitisation
according to Directive 67/548/EC or the CLP Regulation.
