- QSAR prediction:
The value is not an experimental result, however the QSAR model is recommended by the ECHA guidance document on information requirements, and is well documented with regard to validation parameters according to OECD principles. In addition, the substance investigated matches with the parameters of training set compounds and the result is considered as reliable with restriction. - Reason / purpose for cross-reference:

- Calculated LogKow was estimated to be 3.13.
- Executive summary:
The partition coefficient of the test substance was estimated using the recommended QSAR model KOWWIN v1.69, based on Atom/Fragment Contribution (AFC) method. The substance is within the applicability domain (MW, descriptors).
The calculated partition coefficient log Kow is 3.13.

Description of key information
The partition coefficients (LogKow) of the test item, based on the three major known constituent, is estimated to be in the range between 2.98 and 4.57.
Key value for chemical safety assessment
Additional information
No study was conducted on the test chemical iself, as not relevant for an UVCB.
The partition coefficients (LogKow) of the test item was reliably estimated from data on its three major constituents (covering more than 83% of the composition).
The partition coefficients of the 2 major constituents (d,l-limonene and alpha-terpineol) of the test item come from literature (peer-reviewed).The partition coefficient of 1,8-cineol was calculated using the recommended QSAR(EpiSuite). This component falls inside the Applicability domain of the model.
The results are listed below:
- 1,8 -cineol, LogKOW = 3.13
- d,l-limonene, LogKOW = 4.57
- alpha-tepineol, LogKOW = 2.98
As the substance is an UVCB with constituents of different LogKow, the global LogKow of the test item will depend on the composition and loading rate. Therefore we considered the logKow of the three major constituents of the substance. The logKow values will be estimated using the lowest (2.98) and the highest (4.57) LogKow values of the three major constituents.
