Endpoint summary
Administrative data
Description of key information
Physico-chemical properties were determined from experimental testing. Some endpoints were waived, based on surface active properties or chemical structure.
The substance is a solid at ambient temperature, with low volatility.
The critical micelle concentration of the test item was determined to be 70.0 mg/L at 20.0 ±0.5 °C. It is less dense than water (so likely float), with surface-active properties anticipated.
No hazard was identified with regard to physical properties (flammability,explosivity, oxidising properties) based on Regulation (EC) 1272/2008 (CLP regulation).
From granulometry, the substance contains a limited fraction of particles fine enough to be inhaled (approx 10%), also 1% of particles reach the thoracic fraction. However, dust explosion potential should be considered.
Additional information
Summary of relevant physico-chemical properties:
Endpoint (method) | Data |
Appearance (OPPTS Guideline: 830.6302 and 830.6303) | A sample of test item was visually assessed at 20.0 ± 0.5 ºC to be a white, opaque, free-flowing, soft, fine powder, which forms hard clumps (not easily broken down) of various sizes. The color was classified as N 9.5/90.0% R using the Munsell® Color System. |
Melting point (OPPTS/OECD 102/EU A1, DSC Method) | The test item was determined to decompose with softening/melting from approximately 188 °C (461 K) at 102 kPa |
Boiling point (waiving) | Waived because of decomposition of the substance before melting / boiling. |
Relative density (OECD 109/EU A3, gas comparison pycnometer) | The density of the test item was determined to be 976 kg/m3 at 20.0 ± 0.5 ºC. The corresponding relative density was calculated to be 0.976. Less dense than water. |
Particle size distribution (EUR 20268 EN, Sieving and Cascade impactor) | Proportion of test item having an inhalable particle size <100 μm =10.0% Proportion of test item having a thoracic particle size <10.0 μm=1.06% Proportion of test item having a respirable particle size <5.5 μm= 0.044% |
Vapour pressure (OECD 104/EU A4, effusion by VP balance) | 6.2E-7 Pa at 25°C |
Log Kow (waiving) | waiving (surface active substance) |
Water solubility (waiving) Critical Micelle Concentration (CMC) (based on OECD 105/EU A5, ring method) | Water solubility: waiving (surface active substances) The critical micelle concentration of the test item was determined to be 70.0 mg/L at 20.0 ±0.5 °C (CMC is considered as a water solubility limit). |
Surface tension (OECD 105/EU A5, ring method) | The surface tension at a nominal concentration of 1.0 g/L, was determined to be 40.3 mN/m at 20.0 ± 0.5 °C. (surface active). |
Flammability (A10, screening test) Flammability if contact with air or water (data waiving, based on structure and experience) | . No propagation in contact with a flame. No flammable properties expected if contact with air or water. |
Explosive properties (data waiving, based on structure) | No potential. |
Oxidising properties (data waiving, based on structure) | No potential. |
Self-reactive properties (data waiving based on chemical structure) | No potential. |
Organic peroxide (data waiving based on chemical structure) | Not a peroxide. |
Corrosion to metals (data waiving, solid) | Unlikely for solids (method not applicable). |
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
