Additional information

According to REACH Annex IX, 7.16, column 2 the test is scientifically not justified, as the surface active substance is a zwitterion that has no acid-base properties (at environmental relevant pH) which dissociates in water rapidly to a quaternary ammonium ion and the sulphate counter ion.
