Description of key information
Additional information
Experimental results for the biodegradation of the Benzenesulfonic acid, mono-C20-24 (even)-sec-alkyl derivs., para-, sodium salts (generic name: C20 -24 sodium sulfonate) are not available. However, biodegradation studies were performed with three structural analogues of the C20 -24 sodium sulfonate.
Referring to the key study, calcium sulfonate read-across substance (Analogue of CAS 70024-69-0) attained 8 % degradation during the test duration of 28 days (OECD Guideline 301D, Douglas, 1989). With regard to the supporting studies, Sanitised, O. (1996) determined 8.6 % degradation after 28 days (OECD Guideline 301F) for the calcium sulfonate read-across substance (CAS 61789 -86 -4) while 9.1 % degradation was attained for the calcium sulfonate read-across substance (CAS 68783-96-0) after 28 days (OECD Guideline 301B, Sanitised, P., 1995).
Based on the results of these studies, the Benzenesulfonic acid, mono-C20-24 (even)-sec-alkyl derivs., para-, sodium salts is not expected to be readily biodegradable.
