Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

Official classification:

Aquatic compartment

According to Regulation (EC) No 1272/2008 Annex VI Table 3.1 and Table 3.2 the substance holds no relevant classification.

 

Self-classification:

Aquatic compartment

The substance is not acutely and not chronically hazardous to aquatic organisms.

 

According to the criteria outlined in Table 4.1.0(a) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008), 4-morpholinecarbaldehyde (CAS 4394-85-8) is not to be classified as acutely hazardous to the aquatic environment since the lowest acute effect value is greater than 1 mg/L.

As described above, long-term toxicity data are available for algae only. Therefore, classification is based on the available chronic data for this trophic level and based on acute toxicity data for the trophic levels (aquatic invertebrates and fish) not covered by chronic data.

 

Chronic toxicity data:

The substance is rapidly degradable and the EC10 is > 1 mg/L. According to the criteria outlined in Table 4.1.0(b) (ii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008), the substance is not to be classified as chronically hazardous to the aquatic environment.

 

Acute toxicity data:

The L(E)C50 determined for aquatic invertebrates and fish was greater than 100 mg/L, the substance is rapidly degradable, the log Kow is < 4, and the BCF value is < 500. According to the criteria outlined in Table 4.1.0(b) (iii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008), the substance is not to be classified as chronically hazardous to the aquatic environment.

 

It can be concluded that 4-morpholinecarbaldehyde (CAS 4394-85-8) is not to be classified as chronically hazardous to the aquatic environment.
