Reaction mass of 7539-04-0 and pentaerythritol tetrakis(3-mercaptopropionate) and 2-{3-(3-mercaptopropionyl)thiopropionyl}oxymethyl-2-(3-mercaptopropionyl)oxymethyl-1,3-propanediyl bis(3-mercaptopropionate)

Oxidising properties

Reference

Endpoint:

oxidising liquids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the organic substance contains oxygen or halogen atoms which are chemically bonded only to carbon or hydrogen and hence, the classification procedure does not need to be applied

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING

The following statement has been reported by an expert:

A test substance is considered an oxidizing substance when a mixture of the substance and cellulose in a 1:1 ratio (by mass) spontaneously ignites or the mean pressure rise time of the mixture is less than or equal to mean pressure rise time of a 1:1 reference mixture (by mass) of 65% aqueous nitric acid and cellulose.
 
The molecular structure of the main constituents in the test substance do not contain groups that act as an oxidizing agent. The oxygen atoms that are present in the molecular structure of the test substance are chemically bonded to carbon or hydrogen. The purity of the test substance is to be regarded as 100%. The molecular structures of impurities were therefore not taken into account.
 
In conclusion, PEMP product has no oxidizing properties.

Reason / purpose for cross-reference:

data waiving: supporting information

Qualifier:

according to guideline

Guideline:

other: UN ST/SG/AC.10/11/Rev.5: Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Appendix 6 "Screening procedures" (2009)

Deviations:

no

Qualifier:

according to guideline

Guideline:

EU Method A.21 (Oxidising Properties (Liquids))

Version / remarks:

2008

Deviations:

no

Interpretation of results:

GHS criteria not met

Conclusions:

The substance PEMP product has no oxidizing properties.

Description of key information

The substance has no oxidizing properties (based on structural features:UN-MTC App.6, EC A.21).  

Key value for chemical safety assessment

Oxidising properties:

no

Justification for classification or non-classification

Due to the lack of specific functional groups, classification for the hazard 'oxidising liquid' is not required according to CLP Regulation (EC) No. 1272/2008.
