Description of key information

The registered substance is a natural complex substance, for which a partition coefficient derived for the whole substance will be meaningless.

Thus, the assessment is based on log Kow information for each constituent present in the registered substance. The partition coefficients of propanol is 0.25 and the partition coefficient of acetic acid is -0,17.

Key value for chemical safety assessment

Additional information

No study was conducted on the substance itself.

The test item is a natural complex substance. It is a mixture of several constituents, but 2 of them represent the identity of this substance.

Therefore a Weight of Evidence approach was considered and the logP of these 2 known constituents of the substance was gathered.

Literature provided data for 2 known constituents of the substance:

-acetic acid log Kow = -0.17

-propanol logKow = 0.25
