- Conclusions:
Classification: not irritating- Executive summary:
In a study performed according to OECD 404 the test item (27% tris(p-isocyanatophenyl) thiophosphate in ethyl acetate) was shown to be slightly irritating to the rabbit's skin. Erythema grade 1 was observed in all 3 animals 24 and 48 hours after treatment. These effects disappeared on day 3 to 4 after treatment. No systemic intolerance reactions were observed.
