Endpoint:
oxidising liquids
Type of information:
other: expert statement
Adequacy of study:
key study
Study period:
15 March 2012-19 June 2012
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
In accordance with Column 2 of REACH Annex VII, oxidising properties study was not performed because there are no chemical groups associated with oxidising properties present in the molecule of the substance. An expert statement rather than a full study was considered sufficient to cover this endpoint. The statement was prepared according to the EC A.21 and UN guidelines and according to the principles of GLP.

Expert statement

 

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 test substance or its impurities 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 silicium or are part of an oxime group.

 

In conclusion, OS 2600 has no oxidizing properties.

Interpretation of results:
other: no oxidising properties
Conclusions:
The substance was determined to be non-oxidiser.

Executive summary:

Because the molecular structure of the substance does not contain groups that act as an oxidizing agent, the substance is considered not oxidizing (expert statement in accordance with EC A.21 and UN).

Description of key information

OS2600 was found to be non-oxidising.

Key value for chemical safety assessment

Oxidising properties:
no

Additional information

Key study: Because the molecular structure of the substance does not contain groups that act as an oxidizing agent, the substance is considered not oxidizing (expert statement in accordance with EC A.21 and UN).

Justification for classification or non-classification

Based on the molecular structure, the test substance was determined to be non-oxidised and therefore, it is not classified in accordance with CLP Regulation (EC) no. 1272/2008.
