Description of key information

Hydrolytically stable as per OECD 111 preliminary study. The half-life time of Clearlink 1000 at 25°C is >1 year.

Key value for chemical safety assessment

Half-life for hydrolysis:
1 yr
at the temperature of:
25 °C

Additional information

Hydrolysis as a function of pH of the test substance was carried out in accordance with GLP as per OECD guidelines No. 111. The study was performed in duplicate at three pH values 4, 7 and 9. An increase in concentration was observed after 5 days in the preliminary test (Tier 1). Therefore it was concluded that the degree of hydrolysis was < 10% and the performance of the main study (Tier 2) was not required.
