Endpoint:

oxidising solids

Type of information:

other: expert judge

Adequacy of study:

key study

Study period:

Jan. 04. 2006

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

other: It is sufficient to conclude the oxidising properties without further test according to the expert judge.

Qualifier:

according to guideline

Guideline:

other: UN Recommendations on the Transport of Dangerous Goods

Principles of method if other than guideline:

Expert statement, based on assessment of oxygen balance. The oxidising properties of FAT 40824/A were screened based on the UN Recommendations on the Transport of Dangerous Goods (Orange Book. 3rd edition. 1999) where a set of criteria is compiled to evaluate the need for classification of materials as oxidising substances. According to the criteria as described in the above mentioned UN document: the classification procedure using experimental testing need not be applied for organic compounds if the compound does not contain oxygen. fluorine or chlorine.
and
the classification procedure using experimental testing need not to be applied for organic compounds if the compound contains oxygen. fluorine or chlorine and these elements are chemically bonded only to carbon and hydrogen.

GLP compliance:

no

Parameter:

other: Based on chemical structure

Remarks on result:

other: The oxygen balance of FAT 40824/A as calculated according to the UN recommendations and taking carbon hydrogen and oxygen into consideration was found to be negative.

FAT 40824/A contains chlorine and oxygen. Chlorine is bonded to carbon only. whereas a part of the oxygen atoms is bonded to sulphur. Thus. the conditions of the UN recommendations are not fulfilled and the oxygen balance was used as third criterion to predict oxidising properties:

The oxygen balance of FAT 40824/A as calculated according to the UN recommendations and taking carbon hydrogen and oxygen into consideration was found to be negative. In principle this means that there is a surplus of carbon atoms for a complete reaction according to the following reaction scheme:

CxHyOz + [X + (y/4) – (z/2)] – O2 = x CO2 + (y/2) H2O.

Interpretation of results:

GHS criteria not met

Conclusions:

Based on expert statement, it is concluded that FAT 40824/A is considered to be non-oxidising.

Executive summary:

In an expert statement, it is concluded that FAT 40824/A is considered to be non-oxidising and no further test is necessary. This assessment is based on the oxygen balance. FAT 40824/A contains chlorine and oxygen. Chlorine is bonded to carbon only. whereas a part of the oxygen atoms is bonded to sulphur. Thus. the conditions of the UN recommendations are not fulfilled and the oxygen balance was used as third criterion to predict oxidising properties:

The oxygen balance of FAT 40824/A as calculated according to the UN recommendations and taking carbon hydrogen and oxygen into consideration was found to be negative. In principle this means that there is a surplus of carbon atoms for a complete reaction according to the following reaction scheme:

CxHyOz + [X + (y/4) – (z/2)] – O2 = x CO2 + (y/2) H2O.

Description of key information

The test substance is considered as non oxidising.

Key value for chemical safety assessment

Oxidising properties:

non oxidising

Additional information

Justification for classification or non-classification

The test substance has been considered to be non-oxidising based on the expert statement, hence does not warrant classification according to the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
