The substance is corrosive and no study in then required for this
end-point. However, as study has already been conducted according to
Buhler method (OECD Guideline 406). Application of the substance during
this study led to mild to strong skin reactions which confirms the need
for waiving any further test. . No skin reactions were noted at the
challenge sites of the test or untreated control group animals at the 24
or 48-hour observations. Arsenic acid produced a 0% (0/20) sensitisation
rate and was considered to be a nonsensitiser to guinea pig skin.
Positive control exhibited evidence of sensitisation, thus confirming
the susceptibility of this group of animals to dermal sensitisation.
