Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information

Derivation of PNECs

The PNECfreshwater, PNECmarine water, PNECintermittent release, PNECsediment-freshwater, PNECsediment-marine-water and PNECsoil are not derived as no effects have been observed up to the limit doses in the aquatic freshwater studies. Therefore, no hazard for freshwater (sediment) organisms is identified. Furthermore, no hazard for marine water (sediment) organisms or soil organisms is expected.

The PNECstp is calculated by application of an assessment factor (1).

The PNECair and PNECsecondary poisoning are not considered as relevant based on the chemical structure and intrinsic properties of the registered substance.

The utilized procedures are described in detail in the ECHA REACH Guidance of May 2008, Chapter R.10 ("Characterisation of dose [concentration]-response for environment").

 

Environmental classification and labeling

Experimental and reliable QSAR-based results are available for evaluating biodegradation, metabolism and toxicity of Choline chloride towards aquatic vertebrate and invertebrate species. Beside acute toxicity data for three trophic levels (i.e. fish, daphnids and algae), also adequate long-term data are available (i.e. daphnids and algae). Choline chloride was found to be rapidly biodegradable (BASF AG, 1984) and based on the logPow of -3.77 (BASF AG, 1988) and BCF of 3.16 L/kg (Chemservice S.A., 2018b), no bioaccumulation in aquatic organisms is expected. The test substance was found to be not acutely toxic at concentrations upon 500 mg/L or even higher (for details, please refer to the different studies conducted by BASF AG). The most critical NOEC(21d) was found as 30.2 mg/L in an experiment conducted according to OECD 211 with Daphnia magna (MOE Japan, 1999). Based upon these results and in reference to Regulation (EC) No 1272/2008, Choline chloride has not to be classified and labelled with respect to environmental hazards.

Conclusion on classification

In accordance with Regulation (EC) No 1272/2008 (Classification, labelling and packaging of substances and mixtures, amending Regulation (EC) No. 1907/2006), Choline chloride has not to be classified and labelled with respect to environmental hazards.
