readily biodegradable

Additional information

The ready biodegradation test 301A was performed on 2 -Keto-L-gluonic acid in a standard 15 day study. A total of 97% of the material was removed in 5 days. The test material is considered readily biodegradable. In addition, an OECD 303 B simulation test was available for the other main component of keto gulonic acid greens, ascorbic acid. That study also demonstrated that ascorbic acid is rapidly biodegraded. Therefore, keto gulonic acid greens are readily biodegradable.
