Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

No ready biodegradation was identified in a modified Sturm test.

In aerobic surface water as well as in water-sediment systems a fast hydrolysis and reaction to mainly THPI and THPAM was observed. Pathways for mineralisation of Captan were proposed based on these results.

In soil analogous reactions were observed. Captan degrades with a half life-time of 0.91 d mainly to THPI. 

Nevertheless it has to be emphasized that several other studies exist on distribution and elimination of Captan in environmental systems for use of Captan as active ingredient in plant protection products (EFSA (July 2020)).

The results of the studies indicate that neither Captan nor its degradation products are persistent.
