Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion

Any other information on results incl. tables

Based on the physical characteristics of this test substance it is likely that it will be absorbed dermally, and will produce high pH values when in contact with moisture either from the skin or the ocular environment. The oral gavage studies indicate that aqueous preparations of the test substance resulted in trauma (gastrointestinal haemorrhage, erosion and ulceration) and adaptive changes (mucosal hyperplasia in the fore-stomach associated with oedema and cellular infiltration) which are considered to be due to the administration of a strongly alkaline preparation.

Applicant's summary and conclusion

It is considered that performing irritancy studies via the dermal or ocular routes are unlikely to yield any additional data to those already available. It is considered the risk phrase R35 'Causes severe burns' should be assigned to MODA.
