Endpoint summary
Administrative data
Description of key information
Acute toxicity studies by oral, inhalation and dermal routes of administration were waived on the basis of the positive results in the in vitro human epidermis (he-EpiDerm) conducted in accordance with OECD431 test guideline and in vitro eye irritation test (BCOP) conducted in accordance with OECD437 test guideline, or as a consequence of the low respirable fraction and large particle size determined in dustiness testing.
Key value for chemical safety assessment
Acute toxicity: via oral route
Link to relevant study records
- Endpoint:
- acute toxicity: oral
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is classified as corrosive to the skin
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
According to GHS and EU CLP 1272/2008, potassium dicyanoargentate is classified as category 1A for skin corrosion, as an adverse effect was observed within an hour with 3 minutes of exposure to the substance.

Acute toxicity: via inhalation route
Link to relevant study records
- Endpoint:
- acute toxicity: inhalation
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is classified as corrosive to the skin
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
In addition to the GHS and EU CLP 1272/2008 classification for skin corrosion (Category 1A), inhalation studies have also been waived based on dustiness data. Dustiness data for this substance showed that the respirable fraction (2.30 mg/g) is just 4.3% of the total inhalable fraction (52.94 mg/g) which leaves the majority (95.7%) which is not respired (sneezed or swallowed). These data reflect the particle size data (MMAD 34.9µm) when considering that respirable particles are usually under approximately 10 µm.

- Endpoint:
- acute toxicity: dermal
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is classified as corrosive to the skin
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
According to GHS and EU CLP 1272/2008 the test substance is classified as Category 1A for skin corrosion.

Additional information
According to GHS and EU CLP 1272/2008, potassium dicyanoargentate is classified as category 1A for skin corrosion, as an adverse effect was observed within an hour with 3 minutes of exposure to the substance, and category 1 for effects on the eye, as a positive result was determined in a BCOP assay. Consequently, all acute toxicity tests by oral, inhalation and dermal routes of administration have been waived.
Justification for classification or non-classification
Following the waiver for conducting any acute in vivo tests as a consequence of the skin corrosivity and eye irritancy of the test substance, no formal classification for acute toxicity can be assigned. However, it is assumed that, due to the corrosive nature of the substance, a Category 1 result would be expected by either oral, inhalation or dermal exposures.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
