- Remarks:
- QSAR model
- Principles of method if other than guideline:
- The water solubility was determined using a calculation method for the substances generally classified as MOA 1 substances (non-polar narcotics) and ethers, esters, ketones, aldehydes, alcohols, acids and phenols. This algorithm is based on Quantitative Structure-Property Relationship (QSPR) models which have been validated as QSAR models to be compliant with the OECD recommandations for QSAR modeling (OECD, 2004). The determination was performed using regression method in which validated log KOW values are plotted against the log of sub-cooled liquid water solubility from studies of high quality. These have been carried out using one of the methods recommended in the OECD 105 guideline or an adaptation of these. Further to this the water solubility of the WAF is determined by using a series of calculation steps using phase equilibrium thermodynamics.

- Conclusions:
- The apparent water solubility of 19 major constituents of the substance at 25°C is calculated as follows (based on valid QSAR estimations or peer reviewed literature data).
Water solubility (Units: mg/L at 25°C):
constituent 1: 209
constituent 2: 144
constituent 3: 387
constituent 4: 55.6
constituent 5: 0.626
constituent 6: 0.00365
constituent 7 : 0.247
constituent 8: 0.00408
constituent 9: 62.3
constituent 10: 0.277
constituent 11: 0.201
constituent 12: 0.142
constituent 13: 0.0544
constituent 14: 0.176
constituent 15: 0.0712
constituent 16: 0.0905
constituent 17: 25.2
constituent 18: 21.6
constituent 19: 0.0211 - Executive summary:
A calculation method prediction was performed to assess the apparent water solubility of the constituents of the substance. This calculation method predicts the endpoint value which would be expected when testing the substance under experimental conditions in a laboratory following Guideline for Testing of Chemicals No. 105, "Water Solubility" adapted for testing as a mixture using the WAF method. The criterion predicted was the solubility in pure water in mg.L-1 at 25°C.
The water solubility determination of the individual constituents of the mixture was performed using regression method in which validated log Kow values are plotted against the log of sub-cooled liquid water solubility from studies of high quality. These have been carried out using one of the methods recommended in the OECD 105 guideline or an adaptation of these. Further to this the water solubility of the WAF is determined by using a series of calculation steps using phase equilibrium thermodynamics.
Finally the water solubility of 19 components (covering more than 98% of the composition of the substance) has been determined to be between 0.00365 and 387 mg/L each at 25°C.

Description of key information
The apparent water solubility of the major constituents of the substanceat ambient temperature (19 major components covering more than 98% of the composition) has been determined to be between 0.00365 to 387mg/L each at 25°C (calculated based on valid QSAR estimation).
Key value for chemical safety assessment
Additional information
No study was conducted on the oil itself.
The test item is a natural complex substance (NCS). It is a mixture of several constituents, but 19 of them represent more than 98% of that mixture.
Water solubility of the 19 constituents of the test item were calculated using valid QSAR estimations or peer reviewed literature data taking into account the interactions between the constituents of the mixture.
Finally, apparent water solubility of each of these 19 major constituents was reported below
(units: mg/L at 25°C)
constituent 1: 209
constituent 2: 144
constituent 3: 387
constituent 4: 55.6
constituent 5: 0.626
constituent 6: 0.00365
constituent 7 : 0.247
constituent 8: 0.00408
constituent 9: 62.3
constituent 10: 0.277
constituent 11: 0.201
constituent 12: 0.142
constituent 13: 0.0544
constituent 14: 0.176
constituent 15: 0.0712
constituent 16: 0.0905
constituent 17: 25.2
constituent 18: 21.6
constituent 19: 0.0211
As the substance is a UVCB with constituents of different solubility, the global solubility of the substance will depend on the composition and the loading rate (with varying ratio of constituents in the dissolved phase). Therefore we reported the water solubility of the 19 major components of the substance ranging between 0.00365 to 387 mg/L each at 25°C and no single key value was retained (nor calculated weighted WS nor worst-case).
