Details on results:
As the substance has two component elements (acid and amine), the partiition coefficient of both are given.

Any other information on results incl. tables

The log Pow of the two individual components was determined
as follows:


Acid component: Log Pow = -0.311


Amine component: Log Pow = -0.211


Test was conducted at pH 7, which was considered to be the
most environmentally relevant pH. At this pH the substance
is partially ionised.

Applicant's summary and conclusion

Conclusions:
The measured partition coefficient for both element of the substance are well below the threshold value (3) which would indicate a potiential to bioaccumulate.
Executive summary:

As Substances having a log10 Pow of greater than 3 are regarded as having the potential to bioaccumualate in the environment, this study has shown that this substance would not be expected to pose a bioaccumulation risk.
