Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
