Description of key information

Appearance / physical state / colour:

The physical appearance of Isoborneol was observed to be white crystalline solid powder compound with camphor odor.

Melting point/ Freezing point:

The melting point of Isoborneol was determined to be 212 °C.

Boiling point:

The boiling point of Isoborneol was determined to be 212 °C.

Density:

The density of chemical  Isoborneol was estimated to be 0.992 ± 0.06 g/cm3 at 20 °C.

Particle size distribution (Granulometry):

The particle size distribution of Isoborneol was determined by granulometric analysis with rotap sieve shaker. The particle size distribution was determined to be in the range of 147 micron to 52 micron.

Vapour pressure:

The vapour pressure of Isoborneol was estimated to be 4.706 Pa at 25 °C.

Partition coefficient:

The octanol water partition coefiicient i.e., log Pow of test chemical 1,7,7-trimethylbicyclo[2.2.1]heptan-2-ol was determined to be 2.32. On the basis of log Pow value test chemical test chemical 1,7,7-trimethylbicyclo[2.2.1]heptan-2-ol can be considered as hydrophilic in nature.

Water solubility:

The water solubility of Isoborneol was estimated to be 1190 mg/L at 25 °C.

Surface tension:

Based on the prediction done by ACD labs, the surface tension for chemical  Isoborneol was predicted to be 36.2 ± 3.0 dyne/cm.

Flash point:

The flash point of Isoborneol was determined to be 93 °C.

Autoflammability:

Isoborneol did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that Isoborneol is not auto-flammable.

Flammability:

The compound Isoborneol is a flammable solid fallen in category 2 according to GHS criteria.

Explosiveness:

The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties.

Oxidising properties:

The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidizing properties and hence the classification procedure does not need to be applied.
