Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 solids
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Justification for type of information:
Data is from experimental study report
Qualifier:
according to guideline
Guideline:
other: as mentioned below
Principles of method if other than guideline:
Redox titrations are based on a reduction-oxidation reaction between an oxidizing agent and a reducing agent. A potentiometer or a redox indicator is usually used to determine the endpoint of the titration. In permanganometry a slight faint persisting pink color signals the endpoint of the titration because of the color of the excess oxidizing agent potassium permanganate
GLP compliance:
no
Other quality assurance:
ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
Contact with:
potassium permanganate
Key result
Sample tested:
other: not specified
Parameter:
other: ml or mg of KMnO4
Result:
4 790 other: ml/100g
Interpretation of results:
other: not classified based on CLP criteria
Conclusions:
Test chemical was not observed to have any oxidising property.
Executive summary:

Test chemical was observed to have mild oxidising property since 4790 ml of KMnO4 was required for getting the end point of the redox titration for 100 g of test chemical.This oxidation potential was not considered strong enough for classifying the chemical as an oxidising solid. Thus, the chemical is considered as nonoxidising for the purpose of classification.

Description of key information

Test chemical was not observed to have any oxidising property.

Key value for chemical safety assessment

Oxidising properties:
no

Additional information

Test chemical was observed to have mild oxidising property since 4790 ml of KMnO4 was required for getting the end point of the redox titration for 100 g of test chemical.This oxidation potential was not considered strong enough for classifying the chemical as an oxidising solid. Thus, the chemical was considered as nonoxidising for the purpose of classification.

Justification for classification or non-classification

The test chemical was considered as nonoxidising for the purpose of classification.
