Reference
Endpoint:
substances / mixtures which in contact with water emit flammable gases
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 does not contain metals or metalloids and hence, the classification procedure does not need to be applied
other:
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
In accordance with section 1 of REACH Regulation (EC) No. 1907/2006 Annex XI, the does not need to be performed as based on assessment of the chemical structure flammability on contact with water properties are not to be expected and this is supported by experience in handling and use for the substance. According to ECHA Guidance on Information Requirements and Chemical Safety Assessment (Chapter R.7a: Endpoint Specific Guidance, R.7.1.10.8, July 2017), flammability on contact with water testing is scientifically unjustified.

Description of key information

Data waiver for flammability (solids, pyrophoricity and in contact with water) based on physical form and experience of safe handling and use is predicted negative.

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

Testing for this endpoint has been waived because the study is scientifically unjustified. The substance is a liquid and the key value for flammability of liquids is the flash point, which has been determined to be 176.5 °C.

Justification for classification or non-classification

According to Regulation (EC) 1272/2008, Annex I, section 2.6, "Flammable liquid means a liquid having a flash point of not more than 60 °C". The flash point, 176.5 °C, is higher than this value and so the substance should not be classified as a flammable liquid. Further, in accordance with Regulation (EC) 1272/2008, Annex I, section 2.3, if used in an aerosol at > 1%, the aerosol does not need to be considered for classification due to the presence of this substance because the substance has a flash point is > 93 °C. The substance is a liquid under standard conditions (see IUCLID section 4.1, CSR section 1.3) with a freezing point of < -50 °C (see IUCLID section 4.2, CSR section 1.3), so the substance should not be classified as a flammable solid. The substance has a low vapour pressure of 0.0104 Pa at 25 °C(see IUCLID section 4.6, CSR section 1.3), so the substance should not be classified as a flammable gas.
