Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The PNEC freshwater, marine waters, and intermittent release was derived based on the data on acute aquatic toxicity and on chronic aquatic toxicity where available following the guidance (GIRCSR Section 10, ECHA 2008). If combination of studies with confirmed EC50 values or NOECs and limit tests was available for one taxonomic groups, preference was given to the data with confirmed (no) effect concentrations. In the absence of a confirmed (no) effect concentration from testing of one of species of the three trophic levels, the lowest confirmed (no) effect concentration of the other species was used to derive the PNEC.

Conclusion on classification

There were no effects observed up to 100 mg/l (nominal) in any acute aquatic toxicity testing. These results do not warrant classsification according to GHS EU implementation.

Preliminary PBT Assessment

 

An assessment of the PBT status of the substance has been made using all available data. The information available suggests that the substance does not meet the PBT screening criteria as outlined in Directive 2006/121/EC (Appendix A).

 

Persistence Assessment

Within 27 days, a degradation of 37 % was determined for Diethanolamine, propoxylated according to OECD Guideline 302C; and hence Diethanolamine, propoxylated is considered to be "Inherently Biodegradable, not fulfilling specific criteria" (Currenta, 2010). However, since the substance is not readily biodegradable and the biodegradation was less than 70% in the OECD 302 C test, it has to be classified as P, according to the PBT screening criteria.

 

Bioaccumulation Assessment

In the absence of a measured BCF value, the log KOW can be used as a screening criterion for bioaccumulative potential (i.e. >4.5). As the log KOW of the substance is below 4.5, the B/vB criterion is not met. Therefore the substance is identified as not B.

 

Toxicity Assessment

The acute effect information for all three trophic levels is much higher than the screening criterion of 0.1 mg/l. It can therefore be expected that the substance is not toxic towards aquatic organisms.

 

Summary and Overall Conclusions on PBT or vPvB Properties

The overall conclusions, based on the present available data, of the preliminary PBT assessment are that the (screening) criteria for PBT/vPvB are not met and that further testing in the scope of the final PBT assessment is not considered to be required.

 

Emission Characterisation

The substance is not a PBT/vPvB substance, therefore the emission characterisation does not need to be conducted.
