studies were not conducted and met the criteria for data waiver. This is
because the registered substance is produced, supplied and marketed in
the presence of mineral oil solvent. Removal of this solvent is expected
to cause a change in the equilibrium of the chemical structure of the
benzenesulfonic acid and the associated salts resulting in a degradation
of the chemical structure to a structure that is not representative of
the substance being placed on the market in the EU. It is, in
consequence, not possible to undertake any study of the registered
substance in the absence of the solvent. This is further compounded by
the fact that the presence of the solvent changes the physical state of
the registered substance from solid to liquid and will therefore have a
considerable effect on the result of any test conducted on the substance
in water screening tests were performed on analog and structurally
similar substances. These include studies performed according to OECD
Guidelines 301D, 301F and 301B. None of these available studies showed
ready biodegradation after 28-days.
soil adsorption coefficient of benzenesulfonic acid,
di-C10-14-alkyl derivs., sodium salts was determined
by the computer program KOCWIN v2.00 (EPIWIN software
v4.11) by US-EPA (ATL, 2017). The EPIWIN estimates the
organic carbon-normalized adsorption coefficient for
soil (and for sediment), which is designated as Koc.
Two different models are used for this estimation: the
Sabljic molecular connectivity (MCI) method as well as
with the traditional method which is based on logPow.
The traditional method gives a logKoc of 5.793 and the
MCI method reveals a comparable value of 7.101 as
result. The MCI method is taken more seriously into
account due to the fact, that it includes improved
