The biodegradation potential of aromatic hydrocarbons, C10-13, reaction products with branched nonene, sulphonated, sodium salts has been assessed in an inherent test (SCAS test) in combination with Closed Bottle tests. The results reveal that methylnaphthalenesulphonate, and part of the isomers of dimethylnaphthalenesulphonate, degrade. The other constituents are not readily biodegradable. The substance is considered to be inherently degradable not fulfilling the specific criteria outlined in the REACH guidance.
The substance is expected to be stable in the environment on the basis of the chemical structure.
The bioaccumulation test on aquatic species is waived because the available information (log Kow and calculated BCF values) is deemed sufficient for the PBT assessment, classification and labelling and the chemical safety assessment. The log Kow of -3.3 and the chemical structure of the substance suggest a very low bioaccumulation potential. The calculated BCF is 1.41 L/kg wwt (EUSES).
The log Koc of 3.5 was experimentally determined in an adsorption/desorption study according to OECD Guideline 121 (Estimation of the Adsorption Coefficient (Koc) on Soil and on Sewage Sludge using High Performance Liquid Chromatography (HPLC)) under GLP conditions.
