Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
oxidising liquids
Type of information:
read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
weight of evidence
Justification for type of information:
Target and source substances are highly similar, both structurally and chemically.
Reason / purpose for cross-reference:
read-across source
Qualifier:
according to guideline
Guideline:
EU Method A.21 (Oxidising Properties (Liquids))
Deviations:
no
GLP compliance:
no
Contact with:
powdered cellulose
Duration of test (contact time):
ca. 30 s
Sample tested:
test mixture (not specified)
Remarks:
migrated information
Parameter:
mean pressure rise time
Result:
>= 19.31 - < 29.55 s
Sample tested:
reference mixture (not specified)
Remarks:
migrated information
Parameter:
mean pressure rise time
Result:
>= 3.44 - < 4.93 s
Interpretation of results:
other: no oxidising properties
Remarks:
Migrated information
Conclusions:
Due to the fact that the 1:1 mixture, by mass, of test item and cellulose has a mean pressure rise time higher than that if 1:1 mixture, by mass, of 65% nitric acid and cellulose the test item has no oxidising properties.
Executive summary:

Oxidising properties of uronium hydrogen sulphate were evaluated according to EU guideline A.21.

It was concluded that the test item has no oxidising properties.

Description of key information

Uronium hydrogen sulphate has no oxidising properties.

Key value for chemical safety assessment

Oxidising properties:
no

Additional information

Justification for classification or non-classification

Data are conclusive for oxidising properties, but not sufficient for classification according to CLP criteria (Regulation (EC) No 1272/2008).

No classification is proposed for oxidising properties according to CLP.
