Description of key information

A hydrolysis study with polyglycerol is available.

Key value for chemical safety assessment

Additional information

A hydrolysis study was performed with Polyglycerol-3 (read across substance, partly consisting of diglycerol, see section 13 of IUCLID for read across report) according to OECD test guideline 111. The half-life time of the major constituents in Polyglycerol-3 (i.e. diglycerol and triglycerol) at pH values normally found in the environment (pH 4-9) at 25°C were determined to be: pH 4 t½ > 1 year pH 7 t½ > 1 year pH 9 t½ > 1 year. Based on structural similarity, it is expected that these half-life times also apply for the higher polyglycerol constituents in Polyglycerol-3.
