Additional information

As no study is available for Blankophor TP 1160 (CAS 1200448-68-5), a read-across is performed to two studies, which are conducted with structural analogue substances (CAS 16470-24-9 and 16090-02-1). The studies are conducted according to OECD guideline 106 under GLP conditions (BASF, Ciba-Geigy, 1993 & BASF, RCC, 1993). The obtained results show that the amounts of test item adsorbed by the chosen soils ranged from 85% (soil A; sand) to 98 % (soil B; loamy sand) for CAS 16470-24-9 and 58% (soil A; sand) to 84% (soil C; sandy loam) for CAS 16090-02-1. This results in log Koc values ranged from 2.45 to 4 for CAS 16470-24-9 and 2.93 to 3.35 for CAS 16090-02-1.
