Description of key information
Additional information
Abiotic degradation
Phototransformation and hydrolysis are the main abiotic degradation pathways for a substance.The calcium sulfonate target substance (C15 -C36) 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 sulphonate 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 (C15 -C36) 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 (C15 -C36) 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 two representative structures of calcium sulfonate target substance (C15 -C36) possess a logPow of 26.14 and 27.40 (EPIWIN prediction; Chemservice S.A., 2013d), 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., 2013d). Furthermore, based on the assessment of various sulfonates, 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. (2013c). With a mass amount of 94 % and 99.40 % for soil, it is clear that the calcium sulfonate target substance (C15 -C36) will mainly be present in soil and is likely to persist there rather than in other environmental compartments. (Two representative structures were used for prediction.)
A soil adsorption study of the calcium sulfonate target substance (C15 -C36) is technically not feasible. A prediction with KOCWINv2.00 revealed a logKoc range of 15.43 to 16.46 (Chain lengths of C15 and C36, respectively).
No Henry Law constant can be determined using the two representative structures in HENRYWIN v3.20 since both prediction methods result in "incomplete results". For the chemical safety assessment, the value predicted by EUSES v2.1 for the calcium sulfonate target substance (C15 -C36) (2.56E4 Pa*m³/mol) is used in order to calculate the PNECsediment (freshwater and marine water) of the calcium sulfonate target substance (C15 -C36).
