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 clear colorless mobile liquid at ambient temperature It is expected to float over water, because of its low relative density (0.904). The substance contains constituents having different water solubilities and volatilities.

The substance is classified as FLAMMABLE LIQUID, Category 3 based on Regulation (EC) 1272/2008 (CLP regulation) and UN Globally Harmonised System (GHS).

Otherwise, no other 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 11 constituents of the substance (more than 90% of the composition) are in the range between 7.58 and 544 Pa at 25°C

Log Kow 

(Constituent approach - QSAR estimation or peer reviewed literature data on constituents)

The log Kow at 25°C of the 11 constituents of the substance (covering more than 90% of the composition) were determined to be between 2.5 and 6.6.

Water solubility 

(Constituent approach - valid QSAR estimation or peer reviewed literature data on constituents - mixture approach)

The apparent water solubility at 25°C of the 11 constituents of the substance (covering more than 90% of the composition) were determined to be between 0.000473 and 1982 mg/L.

Surface tension

(data waiving)

Waived based on chemical structure of the known constituents 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).
