Endpoint summary
Administrative data
Description of key information
Physico-chemical properties were determined from experimental testing on the standard quality (Items 1 and 2), except Vapour Pressure, Partition Coefficient and Water solubility that were derived from constituents. Some endpoints were waived, based on chemical structure of constituents.
The substance is a liquid at ambient temperature, with low volatility for the major fraction.
In water, it is poorly soluble, much less dense, with no surface-active properties anticipated (i.e. excess will floate).
It has potential for bioaccumulation.
It is classified as Flammable Liquid (cat.3), based on CLP criteria. No other physical hazard was identified.
Note that these parameters may show some variations, due to the UVCB nature of the substance, with both batch-to-batch variations, and two qualities identified.
However, based on typical compositions, all major constituents are common between the "standard" quality and the "high alpha pinene" quality:
- No declassification or more severe classification is anticipated for Flash Point-derived flammability hazard (see Endpoint Summary under 4.11).
- Structure-based waivers for other hazard classes (pyrophoric substances, flammability if contact with water, self-heating, organic peroxides) cover both qualities.
- Also, based on the absence of significant exothermal reaction with the standard quality tested, the DSC thermal stability experiment was considered to cover also the "high alpha pinene" quality with no explosive or self-reactive potential.
Therefore variations in the compositions are not expected to impact the CLP classification of the essential oil.
