Description of key information

Glyoxylic Acid 50% is neither flammable, nor pyrophoric and does not emit flammable gases in contact with water.

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

In accordance with the ECHA Guidance document Chapter R.7a, Glyoxylic Acid 50% does not need to be tested for flammability because this endpoint can be reliably assessed on the basis of the chemical structure, flash point and experience in handling and use:

For liquids the primary value for ease of ignition is the flash point. No flash point could be determined up to 114°C when glyoxylic acid started to boil. This demonstrates that Glyoxylic Acid 50% is not flammable.

Glyoxylic Acid 50% does not fall into a substance category displaying pyrophoric properties. In addition, experience in handling and use show the absence of pyrophoricity.

Glyoxylic Acid exists as a 50 % aqueous solution. Thus, experience in handling and use demonstrates the absence of flammability in contact with water.

Justification for classification or non-classification

The available data demonstrate that Glyoxylic Acid 50% is not subject to classification according to Directive 67/548/EEC and Regulation 1272/2008/EC.
