Description of key information

Additional information

In accordance with Annex IX of the Regulation (EC) No 1907/2006 REACH concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), information regarding phototransformation in air, as well as in water and soil, is not mandatory.

In Annex VIII 9.2.2.1 column 2 of the REACH Regulation, it is stated that a study on the "Hydrolysis as function of pH" does not need to be conducted if the “substance is readily biodegradable". As can be seen in section 5.2, reliable studies indicate the test substance and the degradation product can be considered readily biodegradable. Therefore, a study on the "Hydrolysis as function of pH" does not have to be conducted for DMDMH. However, for information, hydrolysis data for DMDMH are provided.

Although according to Annex IX of the Regulation (EC) No 1907/2006 REACH concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), phototransformation in water is not a mandatory information requirement, Results from a reliable study (Schmidt 1992) are provided for information.
