A study was conducted according to OECD Guideline 111 (Hydrolysis as a Function of pH) to determine the hydrolytic stability of Di(trimethylolpropane) at pH 4, 7 and 9 in the dark at 50°C.
Di(trimethylolpropane) was applied to sterile aqueous buffers at pH 4, 7 and 9 and the buffers were incubated in the dark at 50 ± 0.5°C for up to 5 days. No degradation was observed in pH 9 buffer and <10% degradation was observed in the pH 4 and 7 buffers, therefore, Di(trimethylolpropane) is considered hydrolytically stable under acidic, neutral and basic conditions.
Less than 10% degradation occurred at pH 4, 7 and 9 at 50°C during the initial investigation of a reliable OECD Guideline 111 ('Hydrolysis as a Function of pH') study. Further testing was therefore not conducted, and Di(trimethylolpropane) was concluded to be hydrolytically stable (Hugill and Markowicz, 2016).
