Details on results:
The first-order rat constant for the oxidation of Dechlorane Plus in water was estimated to be 1/10000000000 / sec corresponding to an oxidation half-life in water of 2100 years.
Validity criteria fulfilled:
no
Conclusions:
No valid results, as the method of estimation and calculation was not described.
Executive summary:

The rate of oxidation of Dechlorane Plus in water was estimated as first-order rate constant with 1/10000000000 / sec corresponding to an oxidation half-life in water of 2100 years. The method of estimation and calculation was not reported.

Endpoint:
hydrolysis
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is highly insoluble in water

Description of key information

In accordance with column 2 of REACH Annex VIII, section 9.2.2.1, the study does not need to be conducted for substances highly insoluble in water.

Key value for chemical safety assessment
