Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The item substance is considered readily biodegradable according to studies provided on section 5.2.1. (QSAR Toolbox_Ready biodegradability). Substance mineralisation value extracted from the studies is 89.9%. Therefore, studies related to adsorption-desorption coefficient were not provided and the corresponding data waving was developed on section 5.4.1.
The partition coeficient studies were provided on section 4.7. (OECD Test guideline 107). According to its results, a KOW value of -6,025 was calculated, indicating low lipophilicity. This conclusions are supported by the high solublity rate of the item substance (Section 4.8., OECD Test guideline 105). Bioaccumulation is not expected.
Volatilisation rate is supported by the information provided on section 4.6. (EU Method A.4.). A vapour pressure value of <8 Pa was extracted, showing a negligible volatilisation rate.
In conclusion, the assessed substance is expected to remain on surface water and degrade fast, without reaching further compartments.
Additional information
Although the physical state described on section 1.2 (composition) and 1.4 (Appearance/ physical state/ colour) for the substance Reaction mass of copper digluconate, sodium sulphate and copper sulphate is solid, the manufacturing method (described in section 3.5.1.) only allows substance synthetisation as a dissolution, containing at most a 50% of Reaction mass of copper digluconate, sodium sulphate and copper sulphate.
Therefore, studies for physical hazards determination, were developed using solid substance form, whereas for toxicology and ecotoxicology hazards, the dissolution (≤ 50% Reaction mass of copper digluconate, sodium sulphate and copper sulphate) form was used as stated on guidelines.
In consequence, the substance has been classified taking into account that it always will be in a dissolution in a maximum of 50% of concentration.
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).
