Description of key information

A ready biodegradability study of SPS-100 was performed for 28 days using a method similar to MITI (I) (OECD 301C).  At the end of the test period (28 d) the average biodegradation of SPS-100 was 2%. Thus, the criterion for ready biodegradability (at least 60% biodegradation) was not met. The study is considered to be reliable with restrictions since a toxicity control was not included.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

A ready biodegradability study of SPS-100 was performed for 28 days using a method similar to MITI (I) (OECD 301C). The initial concentration of the test substance was 100 mg/L. At the end of the test period (28 d) the average biodegradation of SPS-100 was 2%. Thus, the criterion for ready biodegradability (at least 60% biodegradation) was not met. The study is considered to be reliable with restrictions since a toxicity control was not included.
