Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Flash point: - 3 °C
Lower explosion limit: 1.6 %(v/v), 1.6 %(v/v), 1.6 %(v/v)
Upper explosion limit: 10.4 %(v/v), 10.4 %(v/v)
No pyrophoricity.
No flammability on contact with water.

Key value for chemical safety assessment

highly flammable

Additional information

The key parameter for the flammability of a liquid is the flash point, which is discussed in IUCLID chapter 4.11.

A number of published values are available for the upper and lower explosion limits of 1,2 -dimethoxyethane. Each source is reporting consistently the same flammability range from 1.6 %(v/v) to 10.4 %(v/v). This information combined with the data on flash point and boiling point leads to the conclusion for the key parameter.

Considering the structure formula and experience in handling and use it can be stated that pyrophoricity and flammability on contact with water is not a concern for the substance.

Justification for classification or non-classification

According to regulation 67/548/EEC the substance meets the criteria for classification as highly flammable.

Criteria for classification as "highly flammable": Liquid substance with a flash point below 21 °C, but not meeting the criteria for "extremely flammable".

Criteria for classification as "extremely flammable": liquid substance with a flash point below 0 °C and a boiling point of max. 35 °C.

As the boiling point is 83 °C the criterion for classification as "extremely flammable" is not met.
