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 clear yellow liquid at ambient temperature.

It is expected to float over water, because of its low relative density (0.8967). Major constituents are slightly soluble to soluble components (20.12 to 3500 mg/L). It is slightly volatile and 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 onRegulation (EC) 1272/2008 (CLP regulation)

Additional information

Summary of relevant physico-chemical properties:

Endpoint (method)

Data

Appearance

(visual)

Registered substance is a clear 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 registered substances stated as <-20°C

Boiling point

(OECD 103/EU A2, Siwoloboff)

The boiling point of registered substance

was stated as 141.5 ± 0.8 7 °C (414.6 ± 0.7 K), corrected to standard pressure (101.325 kPa).

Relative density

(OECD 109/EU A3, oscillating densitymeter)

The relative density (D20/20) of test item was determined to be 0.8967 +/-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 registered substance has been calculated at ca 59 Pa considering the major constituents of the substance (more than 70% of the composition ranged between 14.8 and 253 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 70% of the composition) are ranging between 2.38 and 6.30 but minor constituents can have LogKow>4

Water solubility 

(Constituent approach - literature and QSAR data on constituents)

The water solubility of the major constituents of the substance(more than 70% of the composition) are ranging between 20.12 and 3500 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 51.85 ± 0.23mN/m at 19.8°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 265+/-5°C (between 99.636 and 100,580kPa).

Flammability

Flash-point

(EU A9, ISO 2719 -B, non-equilibrium closed cup) 

Contact with air/water

(Waiving)

Self-heating

(waiving)

With a flash point of 80 +/-2°C, the registered substance is NOT classified as a Flammable Liquid according to Regulation (EC) 1272/2008 (CLP regulation) but it is classified as Flammable Liquid Category 4 according to GHS.

No hazardous reaction anticipated if contact with air or water. Waiving, based on structure and experience.

No self-heating potential. Waiving based on physical state (liquid)

Explosive properties
