Physical & Chemical properties

Endpoint summary

Administrative data

Description of key information

Physico-chemical properties of registered substance were determined from experimental testing,except Vapour pressure, Partition coefficient and Water solubility that were derived in a constituents approach from QSAR estimations on constituents. Some endpoints were waived, based on chemical structure of known constituents or experience in handling and use of the substance.

The substance is a clear yellowish mobile liquid at ambient temperatureIt is expected to float over water, because of its low relative density (0.89). The substance contains constituents having different water solubilities and volatilities.

The substance is classified as NOT FLAMMABLE LIQUID based on Regulation (EC) 1272/2008 (CLP regulation).

No hazard was identified with regard to physical properties (explosivity, oxidising properties, self-heating substance) based on Regulation (EC) 1272/2008 (CLP regulation) and UN Globally Harmonised System (GHS).

Granulometry

(data waiving)

Study scientifically not necessary (liquid)

Vapour pressure

(Constituent approach - QSAR estimations on constituents)

The vapour pressure of the constituents of the substance (10 major components of the substance covering more than 85% of the composition) are in the range between 4.69E-04 ando 533 Pa at 25°C (estimated by QSAR).

Log Kow 

(Constituent approach - QSAR data on constituents)

The partition coefficients of 10 constituents of the substance (covering more than 85% of the composition) were estimated in the range between 3.1 and 8.9 at 25°C (valid QSAR estimations).

Water solubility  

(Constituent approach - QSAR data on constituents)

The apparent water solubilities of the constituents of the substance at ambient temperature (10 components covering more than 85% of the composition) were determined to be between6.41E-063 and 106 mg/L each at 25°C (estimations based on valid QSAR estimations).

Surface tension

(data waiving)

Waived considering that surface activity is not the intended use of the substance (i.e. not a desired property).
