Description of key information

In accordance with column 2 of REACH Annex VII, the study does not need to be conducted as 77PD is hydrolytically unstable at pH 7 (Half life 3.6h).

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
20 °C

Additional information

For 77PD a calculated log Kow of 6.3 was received using Epiwin.

The intermediate hydrolysis product 4[(1,4 -dimethylpentyl)amino]phenol (= N-1.4 -dimethylpentyl-p-phenol) is

characterized by a logKow of 3.1 being calculated with KOWWIN v. 1.67.
