Description of key information

No experimental data are existing for the substances of the category. Soil Adsorption Coefficient has been estimated for all substances with KOCWIN v2.00 and the results are reported below:

BSA, CAS: 98-11-3; Koc: 1.896 l/kg (Kow method)

TSA, CAS: 104-15-4; Koc: 3.821 l/kg (Kow method)

XSA, CAS: 25321-41-9; Koc: 7.698 l/kg (Kow method)

CSA, CAS: 16066-35-6; Koc: 12.18 l/kg (Kow method)

HBSA, CAS: 98-67-9; Koc: 1.511 l/kg (Kow method)

The highest value of CSA has been selected as key value representative of the category for the Chemical Safety Assessment

Additional information

In accordance with Column 2 of REACH Annex VIII not required: the substance has a very low logPow and therefore is likely to have a very low potential for absorption. In addition, the substance is readily biodegradable. An indicative value has been calculated with EPIWIN 4.1 to complete the assessment for all the substances. The value 12.18 l/kg has been reported as key value for safety assessment, as conservative case.
