The adsorption coefficient on soil (KOC) of the test item was determined according to OECD guideline no. 121 [adopted on 22 January 2001] and EU test method C.19 [Directive 2001/59/EC, Official Journal L 225 2001]. The Adsorption coefficient on soil (KOC) was determined as KOC = 5000 to 6300 / log KOC = 3.7 to 3.8 (upper and lower limits of the test item mixture). The result indicate some potential of the test substance to adsorb to soil particles. As isononyl benzoate is readily biodegradable under aerobic conditions and will also be rapidly degraded under unaerobic conditions, a significant transfer of the test item to sediment and soil is considered to be highly unlikely.
