- Executive summary:
In the non-GLP Klimisch 1 study from Bütfering (2012) the particle size distribution of Sodium di(1,3-dimethylbutyl) sulfosuccinate was determined using sieves from 63 to 1400 µm. The mass median aerodynamic diameter (MMAD) of the test item is calculated to be 792 µm.
This study is considered relevant for the risk assessment.
