Reference
Endpoint:
water solubility
Type of information:
(Q)SAR
Adequacy of study:
key study
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 adequate and reliable documentation / justification
Justification for type of information:
QSAR prediction
Principles of method if other than guideline:
The result was obtained using an appropriate QSAR method (see attached QMRF and QPRF for details).
GLP compliance:
no
Type of method:
other: QSAR
Water solubility:
ca. 0 mg/L
Temp.:
20 °C
Remarks on result:
other: pH not available. The solubility in water is described qualitatively as "low".

Low solubility, value estimated, no data available for pH.

Water solubility was determined within the temperature range 20-25°C.

Conclusions:
A water solubility of approximately 1.9E-04 mg/l at 20-25°C was predicted for the hydrolysis product based on an appropriate calculation method. The result is considered to be interpreted qualitatively as "low solubility".

Description of key information

Trimethoxyoctadecylsilane: approximately 1.9E-04 mg/l at 20 -25°C, low solubility (QSAR)

Key value for chemical safety assessment

Water solubility:
0 mg/L
at the temperature of:
20 °C

Additional information

A water solubility value of approx. 1.9E-04 mg/l at 20 -25°C was predicted for the parent substance using an appropriate calculation method. The parent substance is characterized as being of low solubility.
