Hydrolysis

In a DOC Die-Away test performed according to EU Comission Directive 92/69 EEC C.4-A the mean biodegradation of Glyoxylic Acid 50% based on DOC decrease amounted to 98% at the end of the test (day 14). In accordance with Regulation 1907/2006/EC, Annex VIII, 9.2.2.1 column 2, testing does not need to be conducted as Glyoxylic Acid 50% is readily biodegradable.

Biodegradation in water

In a Ready Biodegradability study (OECD 301 A) Glyoxylic Acid 50% was assessed over a 14 day period by the DOC die away test. The nominal test concentration was 30.4 mg/L. The test material attained > 98 % biodegradation after 3 and 10 days, respectively. These results indicate that Glyoxylic Acid 50% is readily biodegradable under conditions of the test.

The reference compound sodium benzoate showed a mean biodegradability of > 90 % within 7 days, thus confirming suitability of the activated sludge.

Adsorption/ desorption

In accordance with Regulation 1907/2006/EC, Annex VIII, 9.3.1. column 2, testing does not need to be conducted based on the physicochemical properties as Glyoxylic Acid 50% has a low octanol water partition coefficient (log Kow < 0).
