Pentadecan-15-olide

Endpoint summary

Additional information

Data for the physico-chemical properties were provided based on studies for the following endpoints: melting and boiling points, relative density, vapor pressure, partition coefficient, water solubility, flash point, flammability.

The results of the studies are reported in the endpoint summary as well as in the accompanying IUCLID database. Data for several endpoints were waived due to intrinsic properties or based on the criteria as laid down in regulation (EC) 1907/2008 Annex VII/IX column 2 or Annex XI.

The substance is a white solid, slighltly soluble in water, with low vapour pressure. No surface-activity nor dissociation are anticipated under environmental conditions.

It is NOT considered as hazardous with regard to physical hazards (flammability, explosivity, oxidising properties).

Summary of relevant physico-chemical properties:

Endpoint	Data
Appearance	White solid block.
Melting point	34.6°C
Boiling point	325°C
Density	990 kg/m^3 The substance is less dense than water.
Vapour pressure	85 mPa at 25°C Not a V.O.C.
Log Kow	5.79
Water solubility	0.3 mg/L at 20°C (in pure water). Considered as slightly soluble. In natural medium, ca 0.02 mg/L.
Flammability	Not flammable (flash point = 160°C). No ignition if contact with a flame. No flammable properties expected if contact with air or water (based on chemical structure and experience).
Explosive properties	No explosive properties anticipated (based on chemical structure assessment).
Oxidising properties	No oxidising properties anticipated (based on chemical structure assessment).
Stability in organic solvents	Not expected to be critical. No instability observed when testing.
Dissociation constant	No ionisable function.
