Remarks:

In accordance with Section 1 of REACH Annex XI, testing was omitted based on the evaluation of structural features and experience in handling. An expert statement rather than a full study was considered sufficient to cover this endpoint. The statement was prepared according to the EC A.12 and UN guidelines and according to the principles of GLP.

Expert statement

 

A test substance is considered highly flammable when it ignites spontaneously in contact with water, or evolves a flammable gas at a minimum rate of = 1 litre/kg of the substance per hour.

 

The molecular structure of the test substance or its impurities do not contain groups that might lead to ignition in contact with water and/or to the evolution of a flammable gas. Moreover the test substance was dissolved in water during the determination of hydrolysis. It demonstrated that the test substance does not ignite spontaneously in contact with water.

 

In conclusion, OS 2600 is considered ‘not highly flammable’ in contact with water.

Interpretation of results:

other: Non flammable based on CLP criteria.

Conclusions:

The substance is considered ‘not highly flammable’ in contact with water (expert statement in accordance with EC A.12 and UN).

Executive summary:

Based on experience during handling and because the molecular structure of the substance does not contain groups that might lead to ignition in contact with water and/or to the evolution of a flammable gas, the substance is considered ‘not highly flammable’ in contact with water (expert statement in accordance with EC A.12 and UN).

Expert Statement

 

A test substance is considered pyrophoric when it ignites within five minutes of coming in contact with air.

 

The molecular structure of the test substance or its impurities do not contain groups that might lead to ignition in contact with air. Moreover the test substance was handled under normal laboratory conditions during this project. It demonstrated that the test substance does not ignite in contact with air.

 

In conclusion, OS 2600 has no pyrophoric properties.

Interpretation of results:

other: Non flammable based on CLP criteria.

Conclusions:

Based on experience during handling and because the molecular structure of the substance does not contain groups that might lead to ignition in contact with air, the substance is considered not pyrophoric (expert statement in accordance with EC A.13 and UN).

Executive summary:

Based on experience during handling and because the molecular structure of the substance does not contain groups that might lead to ignition in contact with air, the substance is considered not pyrophoric (expert statement in accordance with EC A.13 and UN).

Description of key information

The substance is considered  ‘not highly flammable’ in contact with water (expert statement in accordance with EC A.12 and UN).

The substance is considered not pyrophoric (expert statement in accordance with EC A.13 and UN).

Key value for chemical safety assessment

Flammability:

non flammable

Additional information

Flammability in contact with water: Key study: Based on experience during handling and because the molecular structure of the substance does not contain groups that might lead to ignition in contact with water and/or to the evolution of a flammable gas, the substance is considered ‘not highly flammable’ in contact with water (expert statement in accordance with EC A.12 and UN).

Pyrophoric properties: Key study: Based on experience during handling and because the molecular structure of the substance does not contain groups that might lead to ignition in contact with air, the substance is considered not pyrophoric (expert statement in accordance with EC A.13 and UN).

Justification for classification or non-classification

Based on available data, the substance is non-flammable and therefore it is not classified in accordance with CLP Regulation (EC) no. 1272/2008.
