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


The hydrolysis behaviour of 1,3-Propanediol, 2,2-bis(hydroxymethyl)-, allyl ether in dependence of pH was assessed according to the OECD Guideline 111 (‘Hydrolysis as a function of pH’) and EU method C.7 (‘Degradation: Abiotic degradation: Hydrolysis as a function of pH’). Sterile aqueous buffer solutions of different pH values (pH 4, 7 and 9) were treated with the test item solution and incubated in the dark under controlled laboratory conditions (at constant temperatures). Samples were taken at the beginning and after five days for analysis for the test item.

The amount of test item after five days in all three buffer solutions at 50°C was more than 90% of the amount at the start of the test, therefore the test item was considered to be hydrolytically stable (following OECD Guidelines, t(0.5) at 25°C is considered to be greater than 1 year) and no further examination was made beyond the tier 1 assessment. There were no observations which aroused doubts concerning the accuracy of the results and the validity of the study.
