Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No studies on the toxicity of the substance to terrestrial-organisms are available. These studies do not need to be conducted because direct and indirect exposure of the soil compartment is unlikely – [exposure considerations]
Additional information
No studies on the toxicity of the substance to terrestrial-organisms are available. These studies do not need to be conducted because direct and indirect exposure of the soil compartment is unlikely – [exposure considerations]
Despite of the absence of direct or indirect exposure of the soil compartment the PNECsoil was calculated using the equilibrium partitioning method.
It has been noted that the guidance on information requirements and chemical safety assessment(v.4.0, June 2017), Chapter R7b states that “EPM is based on sorption to organic matter and that it therefore, cannot be used for some classes of substances, e.g. when binding behaviour is not driven by lipophilicity (e.g. aromatic amines forming covalent bonds to sediment components, ionisable substances, surface active substances).
To evaluate if the EPM can be used conservatively for cationic surfactants, results available from long term daphnia and sediment tests for 8 different cationic surfactants were used.
The results of the sediment studies were compared to the EPM calculated sediment effects. For 5 out of the 8 the EPM predicted the EC10 for sediment organisms more conservatively than what was observed in the sediment test without applying the additional safety factor of 10 to compensate for ingestion. After including the additional AF (of 10), for all 8 substances the EPM was found to be more conservative than the observed sediment toxicity. The Kp sups-water for these substances ranged from 1040 L/kg to 20100 L/kg. See table included in the sediment paragraph.
New sediment and daphnia data on cationic surfactants will be added to the dataset to in the end generate even more convincing support which will be reported according to the appropriate ECHA guidance.
A similar approach has been applied to the available soil data but for many substances no effects were observed to soil organisms up to 1000 mg/L and these data were therefore not considered suitable.
Finally it should be noted that for all substances in this table real measured sorption data are used which are not normalized to the organic matter content of the soils and that for both sediment and soil the same Kd is used (See EU risk assessment primary alkyl amines).
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.
