Description of key information
Additional information
Phototransformation and hydrolysis are the main abiotic degradation pathways for a substance. Benzenesulfonic acid, di-C10-14-alkyl derivatives, calcium salts is neither susceptible for phototransformation in air, water and soil nor for hydrolysis under environmental conditions. The test substance is a complex mixture (UVCB) for which the test guideline for hydrolysis is not recommended with components having different hydrolytic rates. The representative structure of the test substance contains a phenyl sulfonate functional group and this suggests that hydrolysis at environmentally relevant pH levels and temperatures would not readily occur.
Biotic degradation
The calcium sulfonate target substance (Benzenesulfonic acid, di-C10-14-alkyl derivatives, calcium salts) is not expected to be readily biodegradable based on a biodegradation study with calcium sulfonate read-across substance (CAS 70024 -69-0) according to OECD Guideline 301D (key information). The effects of the test substance were assessed based on chemical oxygen demand (COD) measurements using activated sludge from a domestic wastewater plant as inoculum. The test substance attained 8 % degradation during the test duration of 28 days.
Bioaccumulation
The calcium sulfonate target substance (Benzenesulfonic acid, di-C10-14-alkyl derivatives, calcium salts) is not expected to bioaccumulate. Bioaccumulation in aquatic biota is expected for substances possessing a partition coefficient (logPow) in the range of 4.5 to 6 (ECHA Guidance R.11 PBT Assessment). A higher logPow is probably more an effect of solubility than lipophilicity. The representative structure of Benzenesulfonic acid, di-C10-14-alkyl derivatives, calcium salts) possess a logPow of 26.22, concluding that no strong potential to bioaccumulation is expected. This is supported by the predicted Bioconcentration Factor (BCF) of 70.8 L/kg (Chemservice S.A., 2013). Furthermore, based on the assessment of various sulfonates (Lubrizol, 2012), the hazard profile does neither meet the B nor the vB criterion.
Transport and distribution
A Mackay Level III fugacity modelling calculation was performed with EPIWIN by Chemservice S.A. (2013). With a mass amount of 87.1 % for soil, it is clear that the calcium sulfonate target substance (Benzenesulfonic acid, di-C10-14-alkyl derivatives, calcium salts) will mainly be present in soil and is likely to persist there rather than in other environmental compartments. A soil adsorption study of the calcium sulfonate target substance (Benzenesulfonic acid, di-C10-14-alkyl derivatives, calcium salts) is technically not feasible. A prediction with KOCWIN v2.00 revealed a logKoc of 15.65 (Chemservice S.A., 2013).
No Henry Law constant can be determined using a representative structure in HENRYWIN v3.20 since both prediction methods revealed "incomplete results". For the chemical safety assessment, the value predicted by EUSES v2.1 for the target substance (97.2 Pa*m³/mol) is used in order to calculate the PNECsediment (freshwater and marine water) of Benzenesulfonic acid, di-C10-14-alkyl derivatives, calcium salts.
