P501 		[Rationale for the Classification]
Although there is no data of this substance itself, based on (1) to (4), it is assumed that this substance, which is insoluble in water, also releases the divalent cobalt ion and causes toxicity similar to that of water-soluble cobalt compounds. Therefore, the classification result of cobalt (II) chloride was applied and it was classified in Category 2.

[Evidence Data]
(1) The first step in the toxicity process of cobalt compounds is the release of cobalt ions in vivo. Water-soluble cobalt compounds release cobalt ions into biological fluids outside the cell, and the ions enter the cell through ion channels within the cell membrane. In contrast, poorly soluble cobalt compounds are taken up by organelles (lysosomes) in the cell via a process called endocytosis; cobalt is then solubilized in the acidic environment in the organelles, and the ions are released inside the cell. Evidence for cellular uptake of the different forms of cobalt compounds is provided by in vitro study results (NTP RoC 14th (2016), AICIS IMAP (2014), ECHA RAC & SEAC Final Opinion (Background Doc.) (2020)).
(2) Based on (1), this substance (insoluble cobalt compound) and other four cobalt compounds (water-soluble compounds) are considered to have similar bioavailability. Assuming that all the cobalt compounds are soluble in biological fluids after inhalation or oral exposure and release the divalent cobalt ion at similar rates, data obtained from one cobalt compound can be read across to other cobalt compounds of which data are not available. That is, it is considered that the data can be mutually applicable among the cobalt compounds that can release the divalent cobalt ion (ECHA RAC & SEAC Final Opinion (Background Doc.) (2020), AICIS IMAP (2014)).
(3) Cobalt (II) chloride (CAS RN 7646-79-9) was classified in Category 2 for this hazard class (GHS Classification Result in FY2015).
(4) In the EU classification, this substance was classified as Muta. 2 (REACH registration dossier (Accessed Oct. 2021)).

  • This GHS classification was conducted based on the information sources and the guidance for classification and judgement which are described in the GHS Classification Guidance for the Japanese Government etc. Using other literature, test results etc. as evidence and including different content from this classification result in a label or SDS are allowed.
  • Hazard statement and precautionary statement will show by hovering the mouse cursor over a code in the column of "Hazard statement" and "Precautionary statement," respectively. In the excel file, both the codes and statements are provided.
  • A blank or "-" in the column of "Classification" denotes that a classification for the hazard class was not conducted in the year.
  • An asterisk “*” in the column of “Classification” denotes that “Not classified (or No applicable)” and/or “Classification not possible” is applicable. Details are described in the column of “Rationale for the classification”.
