Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Physical & Chemical properties

Administrative data

Description of key information

Physico-chemical properties of registered substance were determined from experimental testing. Some endpoints were waived, based on chemical structure.

The substance is a yellow powder at ambient temperature, with low volatility. In water,it is soluble, and denser, so likely sink.

Surface-active properties are not expected.

It has no potential for bioaccumulation (log Kow<0.3).

It is not classified as hazardous with regard to physical hazards (flammability, explosivity, oxidising properties) based on CLP criteria.

 Endpoint  Data

 Appearance (visual)

 Registered substance is a white powder at 20 °C and 1 atm.

 Melting point (OECD 102/EU A1, DSC)

No melting point was recorded, the test item inflated and darkened.

 Boiling point (OECD 103/EU A2, DSC)

 No boiling point was recorded under nitrogen atmosphere.

 Relative density (OECD 109/EU A3, air comparison pycnometer for solids)

The mean relative density of test item was determined to be 1.234 +/- 0.030 at 18.6°C +/- 0.3°C

Vapour pressure (OECD 104/EU A4, effusion method weight loss)

 The vapour pressure of the test item is largely lower than 10-3 Pa at 20 °C.

 Log Kow (OECD 117, A24,HPLC method)

 The partition coefficient n-octanol/water of the test item was stated as < 0.3.

 Water solubility (OECD 105, A6, flask method)

 The water solubility was determined as 541 g/L at 30 ± 0.5°C (pH=7).

 Surface tension (waiving)

 Waiving (based on structure, surface activity is not expected and surface activity is not a desired

property of the material)

 Self-ignition temperature (weight of evidence)

Considering various information from studies made on the substance, there is absolutely no reason to expect that the substance Rye extract have auto-flammable properties.

 Flash-point (waiving)

 The flash point of test substance was waived (based on the main form placed on the market, solid).

 Flammability (EU A10/UN method N1)

 Not considered to be flammable.

No ignition in contact with flame. No propagation in contact with a flame: not a flammable solid (CLP/GHS)

No hazardous reaction anticipated if contact with air or water, based on chemical structure and experience in handling and use.

 Explosive properties(data waiving, based on chemical structure)

 Neither explosive nor self-reactive properties are anticipated.

 Oxidising properties (data waiving)

 No oxidising properties anticipated.

 Particle size distribution (laser diffraction )

The median particle size D50 was determined at 85.1 µm.

Organic peroxides (waiving)

 Not a peroxide.

 Self reactive substances (waiving)

 Not a self reactive substance
