Reference
Endpoint:
water solubility
Type of information:
calculation (if not (Q)SAR)
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Value is predicted from model. Thus, it provides an approximation compared to experimental measures.
Qualifier:
no guideline followed
Principles of method if other than guideline:
The water solubility is estimated from the log Kow (WSKOW v1.42). Equation for estimation of the water solubility from log Kow (WSKOW v1.42): Log solubility (mol/L) = 0.796 - 0.854 log Kow - 0.00728 MW + correction
GLP compliance:
no
Type of method:
other: Calculation
Specific details on test material used for the study:

Water solubility:
0 mg/L
Temp.:
25 °C

Log Kow used by Water solubility estimates: 23.51

 

Equation Used to Make Water Sol estimate:

Log Water Solubility (in moles/L) : -25.739

Water Solubility at 25 deg C (mg/L): 1.619e-020

Conclusions:
The predicted value for the water solubility of menhaden oil at 25°C is 1.619e-20 mg/L.
Executive summary:

The given water solubility is calculated from Kow by WSKOW, using EPI Suite. This model predicts a very low value for the water solubility at 25°C (< 2e-20 mg/L). The EPA recommend that EPI Suite is a screening-level tool and should not be used if acceptable measured values are available.

Description of key information

A calculation based on the partition coefficient predicts a very low value (< 2x10-20mg/L) for the water solubility of menhaden oil. The oil is therefore expected to be practically insoluble in water.

Key value for chemical safety assessment

Water solubility:
0 mg/L
at the temperature of:
25 °C
