Description of key information

The substance was not classified as flammable in contact with water, pyrophoric, self-reactive substance, self-heating substance and organic peroxide.

Key value for chemical safety assessment

Additional information

Pyrophoric liquid

In accordance with section 2.9.4 Annex I of Regulation (EC) No 1272/2008 and ECHA guidance on the application of CLP Criteria section 2.10.4.2 the classification procedure for pyrophoric liquids need not to be applied when experience in manufacturing or handling shows that the substance or mixture does not ignite spontaneously when coming into contact with air at normal temperatures. Based on the experience in handling and use the substance is not known to ignite spontaneously when coming into contact with air at normal temperatures. Thus, no study was conducted and consequently the substance has not to be considered for classification as pyrophoric liquid.

 

Substances which, in contact with water, emit flammable gases

In accordance with column 2 of REACH Annex VI and with Regulation (EC) No 1272/2008 Annex I section 2.12.4.1 the classification procedure for this hazard class need not be applied if:

a) The chemical structure of the substance or mixture does not contain metals or metalloids; or

b) Experience in handling and use shows that the substance or mixture does not react with water, e.g. the substance is manufactured with water or washed with water; or

c) The substance or mixture is known to be soluble in water to form a stable mixture.

The substance did not contain metals or metalloids. Therefore the substance has not to be considered for classification as substances which, in contact with water, emit flammable gases.

 

Self-reactive substances and mixtures

In accordance with section R.7.1.10.4 ECHA guidance IR/CSA chapter R.7a, section 2.9.1 ECHA guidance on the application of CLP criteria and UN-MTC section 5.1 appendix 6 the test for self-reactive substances was waived.

The test item does not contain any functional groups quoted in ‘UN Manual of Tests and Criteria’ (fifth revised edition, appendix 6, table A 6.1 and A 6.2) or Bretherick’s – Handbook (6th Edition, Volume 2, p 128 ff) which may indicate explosive or self-reacting properties. Therefore, it can be concluded by expert judgment that the test item does not meet the criteria for self-reactive substances, Thus no classification procedures for self-reactive substances was required and consequently the substance has not to be considered for classification as self-reactive substances and mixtures.

 

Self-heating substances and mixtures

In accordance with ECHA guidance on the Application of the CLP Criteria section 2.11.4.2 and ECHA guidance on IR/CSA chapter R.7a section R7.1.10.7 the test does not to be conducted as in general liquids are not classified as self-heating since the phenomena applies only to solids. Furthermore the test method is not applicable to liquids according to guidance on the Application of the CLP Criteria section 2.11.4.2. Thus no classification procedure for self-heating substances and mixtures was required and consequently and the substance has not to be considered for classification as self-heating substances and mixtures.

 

Organic Peroxide

In accordance with Regulation (EC) No 1272/2008 Annex I section 2.15.1 only organic peroxides have to be tested according to the UN-MTC, Part II test series A-H. Based on the structure it can be concluded that the substance is not an organic peroxide. Thus, no tests were conducted and the substance has not to be considered for classification as organic peroxide.

Justification for classification or non-classification

Based on the molecular structure and experience in handling and use, the substance was not classified and labelled as flammable, flammable in contact with water, pyrophoric, self-reactive substance, self-heating substance and organic peroxide according to Regulation (EC) No 1272/2008 (CLP).
