Justification for classification or non-classification
From the data available for the target chemical dihydrogen (ethyl)[4-[4-[ethyl(3-sulphonatobenzyl)amino](4-hydroxy-2-sulphonatobenzhydrylidene]cyclohexa-2,5-dien-1-ylidene](3-sulphonatobenzyl)ammonium, disodium salt, it is concluded that the chemical is not likely to exhibit skin sensitisation.
