Additional information

To determine the hydrolysis potential of Tinuvin 292 at different environmental relevant pH-values a GLP study according to OECD guideline 111 was carried out. Since Tinuvin 292 consists of two components which are not available separately, the half-lives are given as range. The half-lives at pH 7 (20 °C) range from 1637 – 2568 hours and at pH 9 (20 °C) from 100 – 106 hours (Ciba Inc. 2008)
