No data available for terrestrial organisms.
In accordance with REACH
Regulation (EC) 1907/2006, Annex IX and X, Section 9.4., Colum 2, the
toxicity testing to terrestrial organisms shall be proposed depending on
the results of the chemical safety assessment. According to Annex I of
this regulation, the chemical safety assessment triggers further action
when the substance or the preparation meets the criteria for
classification as hazardous according to Regulation EC 1272/2008 and its
second adaptation 286/2011 or is assessed to be a PBT or vPvB. The
hazard assessment reveals neither a need to classify the substance as
dangerous to the environment, nor is it a PBT or vPvB substance, nor are
there any further indications that the substance may be hazardous to the
In addition, indirect
exposure to soil is unlikely since the substance is readily
biodegradable according to OECD criteria. For substances being
considered as „readily biodegradable“, it can be assumed that they will
be completely biologically degraded within the STP process. Indirect
exposure to soil is not likely e.g. via agricultural use of sewage
sludge since the test substance is readily biodegradable (see IUCLIC Ch.
5.2.1). Furthermore, for substances not passing the STP-process but
being readily biodegradable, it can be assumed that they will be also
biological degraded in the surface water within a short time. Direct
exposure to soil is not likely since the substance is not intentionally
applied to soil. For the substance only industrial and professional uses
with adequate risk mitigating measures are foreseen. Environmental
exposure through widespread uses by consumers is excluded.
The substance has no
potential to bioaccumulate. Regarding the charged molecule at pH 7 the
log Koc was estimated to be 1.62 following the method of Franco & Trapp,
2008, 2009, 2010 (BASF, 2021). Therefore, adsorption to solid soil phase
is not expected (log Koc < 3).
In conclusion no testing is
Toxicity to birds:
In Annex X of the Regulation
(EC) No 1907/2006 REACH concerning the Registration, Evaluation,
Authorisation and Restriction of Chemicals (REACH), it is suggested,
that in case of long term toxicity testing to birds "any need for
testing should be carefully considered taking into account the large
mammalian dataset that is usually available at this tonnage level."
Furthermore, ECHA (2008) states in the "Guidance on information
requirements and chemical safety assessment Chapter R.7c" that "given
that mammalian toxicity is considered in detail for human health
protection, the need for additional data for birds must be considered
very carefully – new tests are a last resort in the data collection
process." Furthermore the substance is not bioaccumulative. Therefore,
and because of reasons of animal welfare, no study on toxicity in birds
