Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

Endpoint:
repeated dose toxicity: oral
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
a sub-chronic toxicity study (90 days) by the oral route does not need to be conducted because an appropriate inhalation study is available and inhalation is the most appropriate route of administration as based on the provided thorough and rigorous exposure assessment
Justification for type of information:
For this endpoint, an analysis based on the components is performed. Based on SIDS report on Sodium carbonate () and sodium hydroxide () and a EU-RAR on sodium hydroxide, no repeated toxicity has to be taken into account whatever the route of administration. Based on Na2S registration data, no NOAEL could be derived from the available study (Cromwell et al, 1979, Effect of copper sulphate, copper sulphide and sodium sulphide on performance and copper stores of pigs).
