Description of key information

Hydrolysis (OECD 111, EU Method C.7) Less than 10 % of the test substance hydrolysed within 5 days at 50 °C, at each of the three pH-values tested. 
According to the Directive it is estimated that the half-life of the test substance in aqueous solution at 25 °C is greater than one year for each pH value .

Key value for chemical safety assessment

Additional information

Less than 10 % of the test substance at pH 4, pH 7 and pH 9 hydrolysed within 5 days at
50 °C.

According to the guideline it is estimated that the half-life of"3-hydroxy-2-(hydroxymethyl)-2-methylpropionaldehyde"in aqueous solution at 25 °C is greater than one year for pH 4, pH 7 and pH 9.

"3-hydroxy-2-(hydroxymethyl)-2-methylpropionaldehyde"is stable to hydrolysis at each pH-value tested.
