Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint summary
Administrative data
Description of key information
Physico-chemical properties were determined from experimental testing.
Some endpoints were waived, based on chemical structure and/or experience.
The substance is a white to yellow powder at ambient temperature.
In water, it is slightly soluble and denser. It is not considered as a surfactant, due to the chemical structure of the substance, non-intended use.
The substance is NOT classified as hazardous with regard to physical hazards (flammability, explosivity, oxidising properties, self-heating) based on Regulation (EC) 1272/2008 (CLP regulation) and GHS.

D2020= 1.1109 Denser than water. |
Vapour pressure (OECD104/EU A4, effusion method: Knudsen Cell ) |
Vapour pressure at 20 °C: 2.04E-06Pa (Low volatility). Result extrapolated. |
log Kow (OECD 117/EU A24, HPLC) |
The log POWof the test item is stated as2.6(mean)at a temperature of 25 ± 0.5 °C and a pH value of 7. |
Water solubility (OECD 105/EU A6, flask method) |
The water solubility of the test item in demineralized water was determined to be: 27.02 ± 0.77 mg/L at 20.0 ± 0.5 °C (pH 6.3) |
Surface tension (data waiving) |
Waived based on chemical structure of the substance, not characteristic of true surfactants and considering that it is not the intended use of the substance (i.e. not a desired property). |
Flash-point (EU A9)
Flammability (N.1 readily combustible solids) |
Waived considering physical state of the substance (solid)
No ignition is observed when the substance is heated with the flame of a gas burner for two minutes. NOT flammable solid (for CLP and UN regulations). |
Flammability if contact with air or water (data waiving) |
No pyrophoric properties expected, or release of flammable gas, based on chemical structure and experience. |
Auto-flammability, Self-heating properties (data waiving) (eq.to EU A15) |
No relative self-ignition or self-heating anticipated, as a low melting solid. |
Explosive properties (data waiving) |
No explosive properties anticipated (based on chemical structure). |
Oxidising properties (data waiving) |
No oxidising properties anticipated (based on chemical structure). |
Self-reactive properties (data waiving) |
No potential, based on chemical structure. |
Organic peroxide (data waiving) |
Not a peroxide, based on chemical structure. |
Corrosivity to metals (data waiving) |
Test method not applicable to solids. |
Granulometry (OECD110/ISO13320/OCSPP 830.7520) |
Median diameter (D50) = 97.7 µm Respirable fraction (<4µm) = 6.5% Thoracic fraction (<10 µm) = 18.0% Inhalable fraction (<100 µm) = 50.5% Dust particles (<500 µm) = 88.5 % (dust explosion potential) |
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
