Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
Toxicity to soil macroorganisms except arthropods
The substance shows no effects up to the limit concentration in acute aquatic toxicity tests. Furthermore, the substance shows no potential for accumulation in soil due to its ready biodegradable properties, its LogPow value and is not ionisable. Therefore,an impact on terrestrial organisms is very unlikely and thus, studies on soil organisms are not required.
However, there are two soil studies available with a fungicide formulation, containing up to 35% pentanols. The results demonstrate that further terrestrial studies with pentanols are not necessary.
In a 14-day acute toxicity study with Eisenia fetida no effects were observed up to 1000 mg test item/kg soil dw (BASF 1996). In a chronic study with Eisenia fetida a NOEC of 305.0 mg test item/kg soil dry weight was determined (BASF 2012). Under the very conservative assumption that these adverse effects are caused by the pentanolic fraction only, a NOEC of 106.75 mg /kg soil dry weight could be extrapolated for the pentanols. Nevertheless, we would expect that a chronic study with Eisenia fetida on pentanol would result in a much higher NOEC value.However, this NOEC based on worst-case assumptions has been used for the PNECsoil derivation.
Toxicity to terrestrial arthropods
The substance shows no effects up to the limit concentration in acute aquatic toxicity tests. Furthermore, the substance shows no potential for accumulation in soil due to its ready biodegradable properties, its LogPow value and is not ionisable. Therefore, an impact on terrestrial organisms is very unlikely and thus, studies on soil organisms are not required.
Toxicity to terrestrial plants
The substance shows no effects up to the limit concentration in acute aquatic toxicity tests. Furthermore, the substance shows no potential for accumulation in soil due to its ready biodegradable properties, its LogPow value and is not ionisable. Therefore, an impact on terrestrial organisms is very unlikely and thus, studies on soil organisms are not required.
Toxicity to soil microorganisms
The substance shows no effects up to the limit concentration in acute aquatic toxicity tests. Furthermore, the substance shows no potential for accumulation in soil due to its ready biodegradable properties, its LogPow value and is not ionisable. Therefore, an impact on terrestrial organisms is very unlikely and thus, studies on soil organisms are not required.
Toxicity to birds
No data on terrestrial toxicity are available. However, in chapter R.10 of the Guidance on information requirements and chemical safety assessment (ECHA 2008, p. 42) concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), it is laid down that "the chemicals of concern with respect to secondary poisoning include lipophilic organic chemicals and some metal compounds". The substance shows a low bioaccumulative (log Pow = 1.29) potential. Thus, a relevant and considerable exposure of birds is not expected. Therefore, and for reasons of animal welfare studies on bird toxicity are not provided.
Toxicity to other above-ground organisms
This is not a standard information requirement in Annex IX/X of Regulation (EC) No 1907/2006.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
