Description of key information

Adsorption coefficient was calculated using partition coefficient as Koc = Pow.

Key value for chemical safety assessment

Koc at 20 °C:
28 183.83

Additional information

According to method C.19 Koc = Pow.

1-octanol/water partition coefficient of Atlen SK is 4.45 (as logPow) at 20 °C.

LogKoc = LogPow = 4.45, recalculate to Koc = Pow = 28183.83

However, in accordance with column 2 of REACH Annex VIII the Adsorption/desorption screening test does not need to be conducted for substances which are readily biodegradable.

[LogKoc: 4.45]
