Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The US EPA is a peer reviewed online database source for ecotoxicological studies conducted globally. While full details on the study are not reported, the database does provide an indication of the study that was conducted. In this case the study is only supporting therefore full details are not required.

Validity criteria fulfilled:
not specified
Conclusions:
A reliable 21 day LD50 value of 176000 ppm has been determined for the effects of dodecanol on the mortality of the bird Gallus domesticus. Full details of the study are not available.

Description of key information

Key value for chemical safety assessment

Additional information

Short-term toxicity

Only short term oral toxicity data to birds exists. A 21 day LC50 value of 176000 ppm has been determined for the effects of dodecanol on mortality of Gallus domesticus (chicken). The study reflects the only value available with this substance for this endpoint.

However this study has not been selected as key since ECHA (2011, Guidance on information requirements and chemical safety assessment Part B: Hazard Assessment Dec 2011, version 2.1) reads: "due to poor correlation between short and long term effects, only long term studies are considered suitable for CSA purposes".

 

Long-term toxicity

In accordance with Column 2 of REACH Annex X, studies on long-term or reproductive toxicity to birds (required in section 9.6.1) do not need to be conducted due to the existence of mammalian data demonstrating no long term systemic effects to higher organisms. Secondary poisoning assessment is not required for this substance because the substance is readily biodegradable, the potential for bioaccumulation is low (BCF = 85 L/kg) and mammalian toxicity data indicate that the substance does not have a potential to cause toxic effects if accumulated in higher organisms.
