Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

A relevant exposure of birds is not expected.

Key value for chemical safety assessment

Additional information

No information concerning effects to birds is available for 1,3,5-trioxane. However, in chapter R.10 of the Guidance on information requirements and chemical safety assessment (ECHA 2008, p. 42) concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), it is laid down that "the chemicals of concern with respect to secondary poisoning include lipophilic organic chemicals and some metal compounds". The substance shows a low adsorptive (log Koc = -0.416) as well as a bioaccumulative (log Pow = -0.5) potential. Hence, a relevant distribution into soil and a considerable exposure of birds is not expected. Therefore, and because of reasons of animal welfare, no study on toxicity in birds is performed.
