Endpoint:
water solubility
Type of information:
(Q)SAR
Remarks:
EPI
Adequacy of study:
weight of evidence
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with limited documentation / justification
Justification for type of information:
Data comes from an online compilation using QSAR model. There is no experimental study reference, however data provide from validated model.
No study was conducted on the oil iself, as not relevant for an UVCB. Literature provided data for the five major components representing about 80%. Fenchone content is about 12% of the UVCB.

Description of key information

Literature provided data for the 4 major components representing about 80% of the UVCB ranging between 2.49 mg/l and 2150 mg/l for the water solubility at 25°C as followed :

Constituent names  CAS nr  Water solubility at 25°C source
thuyone alpha + beta (at about 60%)  546 -80 -5 / 471-15-8 407.7 mg/L EPI suite v4.11
fenchone (at 12%)  1195 -79 -5 2150 mg/L EPI suite v4.11
sabinene (at 5%) 3387-41-5 2.494 mg/L EPI suite v4.11
limonene (at 3%)  5989 -27 -5 13.8 mg/L HSDB - toxnet

Key value for chemical safety assessment

Additional information

As no CSA is required for the tonnage band of concern, no key value was retained.
