Description of key information

As the substance (XDI) reacts with water, this property is not considered relevant for XDI. The Koc and logKoc of the hydrolysis product (XDA) have been calculated to be 12.5 and 1.1, respectively.

Key value for chemical safety assessment

Additional information

Key values for chemical safety assessment:

- Koc of XDA at 25: 12.5

- Log Koc of XDA at 25: 1.1

 

In accordance with section 2 of REACH Annex XI it is technically not feasible to perform the study Adsorption/desorption (section 9.3.1) as the substance reacts with water. The Koc of the hydrolysis product (XDA) has been calculated based on logKow, by using the default QSAR model (for non-hydrophobics).The calculated Koc and logKoc values are 12.5 and 1.1, respectively. This shows that XDA has a very low potential to adsorp to soil/sediment.
