key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Justification for type of information:
Oleyl alcohol is related compounds to Amyl alcohol which is both reagents used in the manufacture of S-allyl O-pentyl dithiocarbonate.
Qualifier:
no guideline followed
Principles of method if other than guideline:
Equilibrium surface tension was measured using the Wilhelmy Plate Technique.
GLP compliance:
not specified
Type of method:
plate method
Surface tension:
66.53 mN/m
Temp.:
25 °C
Conc.:
0.101 other: mg/m2
Remarks on result:
other: 66.53 dyne/centimeter (dyne/cm ) = 66.53 millinewnon/meter (mN/m). Water solubility of Oleyl Alcohol: 0.042mg/L. In the study oleyl alcohol is assumed to be "insoluble". Concentrations are reported as surface concentrations only.
