Description of key information

For p-isopropyphenyl isocyanate no tests on toxicity to microorganisms are

available. Therefore, the available and reliable toxicity test of the main hydrolysis product 4-isoproylaniline is used to draw a conclusion on toxicity to invertebrates for the parent compound. The toxicity to microorganisms was assessed according to a national standard method with activated sludge, which is comparable to the OECD TG 209. With a test duration of 30 min an EC50 of 437 mg/l was obtained (Bayer, 1997).
