Key value for chemical safety assessment

Additional information

In order to estimate the partition coefficient of the substance sulfuric acid, mono-C8-14 alkyl esters, ammonium salts, compds. with triethanolamine (CAS No. 96690-74-3), the results calculated for sulfuric acid, mono-C8-14 alkyl esters, ammonium salts (CAS No. 90583-10-1) and for sulfuric acid, mono-C8-14 alkyl esters, compound with triethanolamine (CAS No. 85665-45-8) are used in a weight of evidence approach. The two read-across substances can be seen as complementary to each other, providing both counter ions present in the target substance. The calculated maximum values are to a good approximation similar (-0.88 for 90583-10-1 and -0.76 for 85665-45-8) and it can be concluded that the partition coefficient of the target substance is lower than the higher of these values, i.e. -0.76. This value is accepted to be used for a chemical safety assessment.

The partition coefficient of the analogue substances was determined using calculation method according to OECD Guideline 107 (EU Method A.8).
