Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

According to Article 13 of Regulation (EC) No. 1907/2006 "General Requirements for Generation of Information on Intrinsic Properties of substances", information on intrinsic properties of substances may be generated by means other than tests e.g. from information from structurally related substances (grouping or read-across), provided that conditions set out in Annex XI are met.

Annex XI, "General rules for adaptation of this standard testing regime set out in Annexes VII to X” states that “substances whose physicochemical, toxicological and ecotoxicological properties are likely to be similar or follow a regular pattern as a result of structural similarity may be considered as a group, or ‘category’ of substances. This avoids the need to test every substance for every endpoint”.

Classification related key information

Readily biodegradable: 74 - 82% in 28 days (OECD 301B); read across

Acute aquatic toxicity:

-             Fish: LC50 (96 h) = 13 mg/L (nominal); read across

-            Aquatic invertebrates: EC50 (48 h) > 100 mg/L (nominal)

-            Algae: ErC50 (72 h) >91 mg/L (measured, geom. mean)

Chronic aquatic toxicity: 

-            Aquatic algae: NOErC (72 h): 7 mg/L (measured, geom. mean)

Conclusion on classification

Reaction mass of bis[2-[2-(2-butoxyethoxy)ethoxy]ethyl] adipate and [2-[2-(2-butoxyethoxy)ethoxy]ethyl](3,6,9,12-tetraoxahexadecyl)adipate (EC 943-330-9) is readily biodegradable. The acute aquatic toxicity L(E)C50 values are > 1 mg/L for fish, aquatic invertebrates and algae. Furthermore the chronic effect concentration is above the trigger value of 1 mg/L (NOErC (72 h): 7 mg/L). Thus, the substance does not need to be classified and labelled according to to the consolidated version of Regulation (EC) No. 1272/2008 (CLP) considering all further amendments.
