Description of key information

Hydrolysis studies are available for the read-across substances formic acid, trimethylolpropane and pentaerythritol:

A 5 day test was carried out to according to EC method C7 to determine the rate of hydrolysis of formic acid. At pH values of 4, 7 and 9 and at a temperature of 50°C each, no hydrolysis occured within the test duration of approx. 5 days.

The hydrolytic behaviour of trimethylolpropane was tested according to OECD 111. The hydrolytic half-life at pH 4.0, 7.0, and 9.0 was determined to be greater than 1 year. Therefore, trimethylolpropane is hydrolytically stable.

A hydrolysis study was conducted by Perstorp AB, to determine the hydrolysis in water at different pH values of the test substance Pentaerythritol. The study was conducted according to the OECD test guideline. Solutions of the test substance in aqueous buffers at pHs, 7, and 9 were stored in a heating cabinet at 50°C for five days. At the end of the storage period, the samples at 50°C were analysed with samples which had been stored at -20°C, and the difference calculated. It was concluded that no hydrolysis was observed under the conditions investigated.
