Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The substance is not flammable (no solid).

Key value for chemical safety assessment

Additional information

Burning rate, solid:

According to REACH legislation, Annex VII, column II flammability does not need to be conducted since the substance is a liquid. Flammability for liquids is expressed as flash point.

Contact with water:

The structural formula (see page 9) of the test item contains none of the functional groups quoted in Manual of Tests and Criteria (fourth revised edition, appendix 6, article 5.3) which may react with water to emit flammable gases. Therefore, it can be concluded by expert judgement that ‘Ethane-1,2-diol, propoxylated' does not emit flammable gases in contact with water. The determination according to EU Method A.12 (Flammability (Contact with Water)) and UN Test N.5 (Flammability (Contact with water)) is not necessary (Currenta, 2009).

Pyrophoric properties:

Experience in production or handling shows that the substance does not ignite spontaneously on coming into contact with air at normal temperatures (i.e. the substance is known to be stable at room temperature for prolonged periods of time) (Currenta, 2010).

Self-heating substances and mixtures:

The substance is a liquid. Liquids do not demonstrate self-heating properties unless they are adsorbed on a large surface.
