Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Applicant's summary and conclusion

The biodegradation of tartaric acid (mTA) complexed with iron (III) in soils is comparable to the half-life of tartaric acid i.e. 10 days at most because the stereoisomeric composition of tartaric acid (mTA), and Fe(III) complexation do not or only slightly influence the degradation rates in soils. The short half-life and mineralization of tartaric acid (mTA) complexed with iron (III) in soil is in line with its ready biodegradability, and evidence of its conversion into carbon dioxide and water by microorganisms. Tartaric acid (mTA) complexed with iron (III) will also degrade in water-logged soils because of the ability of microorganisms to convert this substance in the absence of oxygen (anaerobic conditions). Finally, the antropogenic tartaric acid (mTA) complexed with iron (III) will become part of the natural LMW organic acid pool.
