Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 results reflect that the ultimate fate of 1-tetradecanol is dependent on its route of release into the environment.1-Tetradecanol released to air would partially precipitate to soil and water. There is relatively little movement between soil and water, because transfer via the air compartment is very slow, for a substance of low volatility. In water, the adsorption coefficient of 1-tetradecanol results in significant adsorption to sediment.

Applicant's summary and conclusion

Conclusions:
Two models have been used to predict distribution of decanol in the environment:
- The 1997 Level I model implemented as 'EQC'
- The 1999 Level III model, available on the Canadian government web site.

The results reflect that the ultimate fate of 1-tetradecanol is dependent on its route of release into the environment. 1-Tetradecanol released to air would partially precipitate to soil and water.
