Description of key information

Dimethyl glutarate was readily biodegradable. By day 7, 70% biodegradability was achieved. The Theoretical Oxygen Demand was calculated as 1.6 mg O2 per mg of active substance.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

The study available for this endpoint (Gannon J., 1997) was conducted (equivalent or similar to) according to the following OECD Guideline 301 D (Ready Biodegradability: Closed Bottle Test) and GLP principles. The purity and composition of the sample is not described.

In a Closed Bottle System. biodegradation was measured as the loss of dissolved oxygen within the closed bottle. If the dissolved oxygen loss at Day 28 is >= 60%, and this level of biodegradability has been exceeded within 14 days of exceeding 10% of biodegradability, then the chemical is considered "Readily Biodegradable."

Dimethyl glutarate was readily biodegradable. By day 7, 70% biodegradability was acheived. The Theoretical Oxygen Demand was calculated as 1.6 mg O2 per mg of active substance.
