Physical & Chemical properties

Endpoint summary

Administrative data

Description of key information

Physico-chemical properties of registered substance were determined from experimental testing,except water solubility, partition coefficient and vapour pressure that were derived from available data on constituents in a constituents approach. Some endpoints were waived, based on chemical structure of constituents or experience in handling and use of the substance.

The substance is a pale yellow liquid at ambient temperature

It is expected to float over water, because of its low relative density (0.8989). The major constituents are insoluble to soluble components (0.01283 to 1590 mg/L). They exhibit only low volatility (up to ca 21.3 Pa).

The substance is considered to have surface active potential.

It is NOT classified as hazardous with regard to physical hazards (flammability, explosivity, oxidising properties, self-heating, self reactive substance and organic peroxide) based on Regulation (EC) 1272/2008 (CLP regulation)

Additional information

Summary of relevant physico-chemical properties:

Endpoint (method)

Data

Appearance

(visual)

Registered substance is a pale yellow organic liquid at 20 °C and 1 atm.

Melting/Freezing point

(description of the test item state at -20°C as recommended in EFFA/EFEO guideline)

The Melting / freezing point of test item was stated as <-20°C

Boiling point

(OECD 103/EU A2, Siwoloboff)

The boiling point of test item was stated as 189.2 ± 0.4 °C (462.3 ± 0.4 K) at 101.325 kPa

Relative density

(OECD 109/EU A3, oscillating densitymeter)

The relative density (D20/20) of test item was determined to be 0.8989 +/-0.0002

less dense than water

Granulometry

not applicable (liquid)

Vapour pressure

(Constituent approach - literature and QSAR data on constituents)

The Vapour Pressure of the major constituents of the substance (more than 78% of the composition) are ranging between 3.04 and 21.3 Pa at 25°C

Log Kow 

(Constituent approach - literature and QSAR data on constituents)

The logKow of the major constituents of the substance  

(more than 78% of the composition) are ranging between 2.97 and 6.99.

Water solubility 

(Constituent approach - literature and QSAR data on constituents)

The water solubility of the major constituents of the substance (more than 78% of the composition) are ranging between 0.01283 and 1590 mg/L at ambient temperature.

Surface tension

(OECD 115/EU A5, plate method)

The surface tension of an aqueous solution of the test item (90% of the saturation solubility) was determined to be 54.15  ± 0.06mN/m at 19.9°C.

As the result is below the threshold value of 60mN/m, the substance is considered to have surface active potential under the experimental conditions based on EUA5 criteria.

However since the structures of the constituents of the substance are not characteristic of true surfactants and considering that it is not the intended use of the substance (i.e. not a desired property), this conclusion should be taken with caution.

Auto-ignition temperature

(EU A15)

Auto-ignition of the test item was determined as 260+/-5°C (between 99.828 and 100,105kPa).

Flammability
