The hydrolytically behaviour of the substance was investigated following OECD Guideline 111. Rapid hydrolysis at pH 4 and pH 7 within a few minutes was observed. Degradation of the substance at pH 9 at 20°C was slowly enough to investigate the hydrolysis behaviour of the substance, including calculation of half-life time and hydrolysis rate. Analysis of the substance was performed by HPLC. The calculated half-life was 1.9 h at pH 9 and 20°C. Determination of hydrolysis products was not possible, with the analytical method used to follow degradation of the parent substance. The substance is a reaction product with complex composition and is assessed as UVCB substance. It is assumed that hydrolysis of the substance results in a mixture of partially complex hydrolysis products, known as A) 2-ethyl-2-(hydroxymethyl)propane-1,3-diol, propoxylated, reaction product with methyl 3-oxobutanoate and B) 3-aminopropyldimethylamine.
