CAS number: -
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 their physical state ((mostly) solid(ish) and/or
extremely viscous resins) leads to further difficulties for testing.
the very complex nature of the test item (UVCB, resinous material very
viscous and sticky, 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.
substance is a dark-green to brown-green resinous material, very
viscous and sticky at ambient
temperature and is flowable at 65 -70°C. It
is expected to sink into the water, because of its relative density is 1.0567.
hazard was identified with regard to physical properties
oxidising properties, self-reactive, self-heating substance) based on
Regulation (EC) 1272/2008 (CLP regulation) and
Summary of relevant physico-chemical
Appearance at 20 °C and 1 atm. (visual)
Dark green to brown-green resinous material (viscous and sticky)
Note: According observations reported in endpoint 4.4, the substance is flowable at approximately 65 -70 °C
(OECD 102/EU A1, capillary method)
Melting range = (0.3 °C - 14.2 °C) (273.5 to 287.4 K)
(OECD 103/EU A2, Cottrell)
No clear initial boiling point was determined using dynamic method and signs of decomposition were observed
(OECD 109/EU A3, pycnometer method)
1.0567 ± 0.0005 g/cm3 at 20.0 ± 0.2 °C
D20/4 = 1.0567
study scientifically not necessary (not granular / powder)
(OECD 104/EU A4,
717 Pa at 20.0 °C and 985 Pa at 25°C (interpolation)
Note that the result obtained on this kind of substance should be largely influence by small amounts of volatile constituents and these values don't represent the major part of the substance. Therefore the result should be considered with caution when used for subsequent assessment (worst case).
Waived based on technical issue and poor knownledge of the composition of the substance.
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
Waived considering that surface activity is not the intended use of the substance (i.e. not a desired property).
285°C (1005.2 - 1013.6 hPa).
Flammability (N.1 readily combustible solids)
Self-heating substances/mixtures (data waiving)
132.5°C at 1013 hPa => NOT classified under CLP & GHS.
Note that the result obtained on this kind of substance should be largely influence by small amounts of volatile constituents and the result doesn't represent the major part of the substance.
No propagation of a flame: NOT a flammable solid (CLP/GHS).
Waived based on experience in handling, testing and use and chemical structure of known constituents of the substance.
NOT flammable if contact with air or water
Waived based on the physical state (liquid)
NO self-heating substance anticipated.
(DSC screening test)
NO explosive properties are anticipated
Note also: NO classification for self-reactive substance
Waived based on technical issue and chemical structure of known constituents of the substance.
LOW potential for oxidizing properties
variations are possible with composition (UVCB substance).
