The surface tension of pentadecanol, branched and linear is not quantified. A value in the range ca. 30 mN/m to ca. 66.5 mN/m at ca. 90% saturated aqueous solution is estimated by read-across from undecan-1-ol and (Z)-octadec-9-enol.
A preliminary assessment by calculated
Hydrophilic Lipophilic Balance suggests that no surface tension lowering
property would be expected on the basis of structure alone.
The main purpose of determining surface
tension is to assess whether a substance is a surfactant and not able to
have a log Kow done. The structural analogue n-octanol, which is
considerably more soluble in water than pentadecanol,
branched and linear, is regularly
used with water in the classic two-phase partitioning experiment (e.g.
OECD Guideline 107). Octanol and all alcohols do phase separate which
suggests that emulsification is not so strong as to create issues with
measurement of partitioning or other fate or effects studies.
The Category hypothesis is that the long
chain linear aliphatic alcohol family has at its centre an homologous
series of increasing carbon chain length, which is associated with a
consistency and predictability in the property data across the group,
for the physicochemical, environmental, and toxicological property data
sets. Predictivity of the surface activity behaviour of pentadecanol,
branched and linear being
intermediate between that of undecan-1-ol and (Z)-octadec-9-enol is
considered to be reasonable.
