Description of key information
Additional information
Stability
Ditolylether disulfonic acid disodium salt, isomer mixture is considered as stable. In a water-solubility study, ditolylether disulfonic acid disodium salt, isomer mixture was stable after 72 hours and at 30°C. Furthermore, with regard to its chemical structure ditolylether disulfonic acid disodium salt, isomer mixture is not expected to hydrolyse under environmental conditions.
Biodegradation
Ditolylether disulfonic acid disodium salt, isomer mixture is not readily biodegradable, no biodegradation was observed within 28 days.
Bioaccumulation
Since no experimental determined BCF value was available the BCF for representative constituents of ditolylether disulfonic acid disodium salt, isomer mixture was estimated by calculation. As the log Kow for each representative constituent is below 5.0, a general log BCF of 0.50 is assigned by the program, resulting in a BCF of 3.162 L/kg wwt, indicating that ditolylether disulfonic acid disodium salt, isomer mixture has no potential to bioaccumulate.
Adsorption/desorption
For ditolylether disulfonic acid disodium salt, isomer mixture no experimental results describing the adsorption properties are available. Under environmental relevant pHs, ditolylether disulfonic acid disodium salt, isomer mixture exists predominantly in the dissociated form, based upon its pKa values. At pH 5 to 9, ditolylether disulfonic acid disodium salt, isomer mixture will be deprotonated resulting in the corresponding anion. As deprotonated substances in particular generally have a low adsorption potential, adsorption for the dissociated form of ditolylether disulfonic acid disodium salt, isomer mixture is not expected. Nevertheless, in order to predict the distribution of ditolylether disulfonic acid disodium salt, isomer mixture between the organic phase of soil or sediments and the porewater calculations were performed using different estimation methods which are incorporated in the Estimation Program Interface (EPI) Suite version 4.1. The QSAR determination of the carbon partition coefficient for ditolylether disulfonic acid disodium salt, isomer mixture revealed values of 0.044 to 1.346 L/kg (log Kow method) and 2424 to 82790 L/kg (MCI method) relating to the dissociated and non-dissociated form of representative constituents of ditolylether disulfonic acid disodium salt, isomer mixture, respectively. As Koc values estimated based upon the log Kow method considers the anionic character of ditolylether disulfonic acid disodium salt, isomer mixture the lowest value of 0.044 l/kg is taken into account for further assessment, indicating a low potential for adsorption.
Henry's Law Constant
The Henry's Law Constant (HLC) for representative constituents of ditolylether disulfonic acid disodium salt, isomer mixture was predicted using the QSAR calculation. The estimated HLC was 3.20E-12 Pa m³/mol. Ditolylether disulfonic acid disodium salt, isomer mixture is considered as essentially non-volatile from water.
