Description of key information
The substance belongs to a group of Natural Complex Substances (NCS): UVCB sub-type 3, where the source is biological and the process is refinement (See ECHA Guidance on Identification and naming of substances under REACH); such as: exudates, resinoids and concretes that are well-known to be very difficult to analytically assess. These complex UVCB substances contain a large number of constituents with different volatility and solubility (mostly low solubility); the composition can be widely unknown and being (mostly) solid(ish) and/or extremely viscous resins their physical state leads to further difficulties for testing.
Considering the very complex nature of the test item (UVCB,solid, crystal light brown, mainly composed of unknown constituents), physico-chemical properties of the registered substance were determined from experimental testing when possible. Some endpoints were waived, based on the experience in handling, testing and use of the substance and on the chemical structure of the known constituents. We also considered waiving based on the technical issues due to the complex nature of such UVCB substance especially when the information obtained from testing was not relevant or of practical use and irrelevant for subsequent assessments.
Based on available data, and according to both GHS and CLP criteria, the substance is NOT classified for physical hazards (but the dataset is incomplete). The substance is described as a solid, so Aspiration Hazard will Not apply.

Summary of relevant physico-chemical properties:
Endpoint (method) |
Data |
Appearance at 20°C and 1 atm.(visual observation) |
The test iem was described as a light brown crystallized solid. |
Melting/Freezing point (OECD 102/EU A1, DSC) |
The melting point is given in a range of: 38.27 °C to 69.53 °C (311.42 K to 342.68 K) with the lowest peak maximum of 57.13 °C (330.28 K) |
Boiling point (OECD 103/EU A2, DSC) |
The boiling point is also given in a range of: 252.73 °C to 353.24 °C (525.88 K to 626.39 K) with the highest peak maximum of 312.83 °C (585.98 K) |
Relative density (OECD 109/EU A3, pycnometer) |
The density of the test item was calculated as 1.1412 ± 0.0068 g/cm3 at 20.0 ± 0.2°C. |
Granulometry (data waiving) |
Study scientifically not necessary (not granular / powder) |
Vapour pressure (OECD 104/EU A4, static method) |
The vapour pressure of the test item was calculated as 387 Pa at 20.0 °C and 463 Pa at 25.0 °C. |
log Kow (data waiving + QSAR estimation on knwon constituents) |
Waived based on technical issue and poor knownledge of the composition of the substance + QSAR estimation on known constituents of the registered substance. |
Water solubility (data waiving) |
Waived considering the very complex nature of the test item, the information obtained from testing is considered as not relevant or of practical use for subsequent assessments. |
Surface tension (data waiving) |
Waived based on non-intended use of the substance (i.e. not a desired property). |
Auto-ignition temperature (data waiving) |
waived (liquid and melting point below 160°C) |
Flash-point ( EU A9, equilibrium method) Flammability (N.1 readily combustible solids) Flammability water&air (data waiving) Self-heating substances/mixtures |
waived (solid) No ignition was observed throughout the course of the test. Waived based on experience in handling and use and chemical structure of known constituents of the substance. NOT flammable if contact with air or water waived. |
Explosive properties (data waiving) |
Waiving based on experience on this type of substance and chemical structure of known constituents. Low potential for explosive properties |
Oxidising properties (data waiving) |
Waiving based on technical issue and chemical structure of known constituents of the substance. Registered substance is considered to have low potential for oxidizing properties. |
Slight variations are possible with composition (UVCB substance).
