Description of key information

The data show that at pH 4, 7 and 9 essentially no hydrolysis occured within 5 days at 50 ± 0.1 °C. According to the EC test guideline, Hydroxypropinol can therefore be considered to be hydrolytically stable (t½ > 1 year at 25 °C) and no further testing is necessary.

Key value for chemical safety assessment
