Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is readily biodegradable
Justification for type of information:
No phototransformation study is provided. In general, fate and environmental data requirements do not need to be fulfilled because algae and algal products, used as soil amendment, are readily transformed in elements naturally present in the environment. Furthermore, seaweed extracts including Ascophyllum nodosum extracts are included in Annex I of Directive 91/414/EEC, which requires a reduced package of studies for Plant Protection Products made from plants or plants extracts (SANCO Draft Working Document 10472/2003/rev. 5).

Regarding the sentence "in vitro micronucleus study was NOT performed”, I think it was a typing error. It should be “in vivo micronucleus study was NOT performed”
