According to column 2 of EC 1907/2006 Annex VIII the testing on
“Adsoption/Desorption” does not need to be conducted if the substance
has a low potential for adsorption (e.g. the substance has a low octanol
water partition coefficient) or if the substance and its degradation
products decompose rapidly. Based on log Kow ≤ 3 the potential for
adsorption of alkyl ether sulfates is quite low. Hence, testing of the
adsorption and desorption attributes of the category members is not
However, to estimate PNEC sediment by the equilibrium partitioning
method data of the sorption behavior of alkyl ether sulfates are needed.
Since measured sorption values are not available for the test substance
the Koc was calculated using the QSAR for “Predominantly hydrophobics”
from Sabljic & Gusten (1995).
Based on calculated log Kow-value of -0.858 the calculated log Koc
value for AES (C9 -11, 1 -2.5EO) Na (CAS 160901 -28 -0) is -0.595
(corresponding Koc = 0.25 L/kg).
