Description of key information
An OECD 301D (Ready Biodegradability: Closed Bottle Test) study was conducted using the test substance Betadet SHR. Results demonstrate that the test substance can be considered to be readily biodegradable, given that the substance attained 94% degradation after 28 days whilst meeting the 10-day window (showing 25% degradation on day 6 and 77% degradation on day 12 of the study).
The reference substance, sodium benzoate, attained 93% degradation after 28 days, thereby confirming the suitability of the test method and culture conditions. Furthermore, the toxicity control, attained 87% degradation after 28 days, confirming that Betadet SHR was not toxic to the sewage treatment microorganisms used in the study. As such, the study is considered to be valid.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
