Additional information

In order to estimate the surface tension of the substance sulfuric acid, mono-C8-14 alkyl esters, ammonium salts, compds. with triethanolamine (CAS No. 96690-74-3), the experimental results obtained 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 surface tensions of read-across substances were determined by the ring method according to EU Method A.5. Following the obtained results, sulfuric acid, mono-C8-14 alkyl esters, ammonium salts, compds. with triethanolamine (CAS No. 96690-74-3) should be regarded as being surface active material.
