with
Genotoxicity:
negative
Cytotoxicity / choice of top concentrations:
other: Maximum dose tested: 38.58 mg/plate (highest non-cytotoxic estimated dose in the experiment)
Vehicle controls validity:
valid
Positive controls validity:
not specified
Additional information on results:
Based on published experimental data on the analogue Sodium Acetate which is considered to be not mutagenic on S. typhimurium TA 92, TA 1535, TA 100, TA 1537, TA 94, and TA 98, with metabolic activation, and applying the read-across approach, the substance Calcium acetate is also considered as not mutagenic under test conditions.

The analogue Sodium acetate which shares the same functional group with Calcium acetate, also has comparable values for the relevant molecular properties. These properties are:
- a low log Pow value, which is -3.72 for Sodium Acetate and -1.38 for Calcium acetate,
- a high water solubility, which is 1.25 g/mL at 25 ºC for Sodium acetate and 1000 g/L at 25 ºC for Calcium acetate, and
- similar molecular weights, which are 82.0 for Sodium acetate and 158.17 for Calcium acetate.
Remarks on result:
other: all strains/cell types tested
Remarks:
Migrated from field 'Test system'.

Any other information on results incl. tables

The substance Calcium Acetate is also considered as not mutagenic on S.typhimurium TA 92, TA 1535, TA 100, TA 1537, TA 94, and TA 98, with metabolic activation.

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information):
negative with metabolic activation

The substance Calcium Acetate is also considered as not mutagenic on S.typhimurium TA 92, TA 1535, TA 100, TA 1537, TA 94, and TA 98, with metabolic activation.
Executive summary:

Based on published experimental data on the analogue Sodium acetate (repoted under endpoint record 07.06.01_01 NaAc) which is considered to be not mutagenic on S. typhimurium TA 92, TA 1535, TA 100, TA 1537, TA 94, and TA 98, with metabolic activation, and applying the read-across approach, the substance Calcium acetate is also considered as not mutagenic under test conditions.
