Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint:
in vitro gene mutation study in bacteria
Remarks:
prediction from hazard class
Type of information:
calculation (if not (Q)SAR)
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Automatic calculation with MeCLas tool
Reason / purpose for cross-reference:
reference to same study
Reason / purpose for cross-reference:
reference to other study
Principles of method if other than guideline:
Genetic toxicity potential of the UVCB potential was determined by classifying based on Mixture rules from EU CLP (additivity formula of classified components to derive hazard class). The classification criteria were used to estimate effects.
Type of assay:
other: prediction from hazard class
Remarks on result:
no mutagenic potential (based on QSAR/QSPR prediction)
Remarks:
Genetic toxicity potential of the UVCB potential was determined by classifying based on Mixture rules from EU CLP (additivity formula of classified components to derive hazard class). The classification criteria were used to estimate effects.

According to MeClas, the substance is not classified as germ cell mutagen.

Conclusions:
Interpretation of results: negative

Good quality study with result derived on basis of the Classification outcome (Mixture toxicity rules) from the reasinable worst case sample of the substance (maximum of typicals across industry as defined in IUCLID section 1.2/1.4). The analysed UVCB sample is not classified for germ cell mutagenicity.
Executive summary:

The study provided a conservative estimate, derived on basis of the classification outcome (mixture toxicity rules) from a reasonable worst-case sample of the substance using mineralogical information from the representative sample. 

 

Validity of the model used:

1. Defined endpoint: the endpoint is a REACH compliant defined endpoint

2. Unambiguous algorithm: EU CLP guidance based summation formula to determine classification, followed by back-calculation to related hazard criteria

3. Applicability domain: applicable to classify complex metal containing materials. 

4. Mechanistic interpretation - metal species: the tool translates the elemental composition into a mineralogical composition relevant for classification.

Endpoint:
in vitro gene mutation study in mammalian cells

Additional information

Genetic toxicity is driven by the characteristics of the individual UVCB constituents.
Relevant information on the individual UVCB constituents is reported in Section 7 Summary.
