Endpoint summary

Administrative data

Description of key information

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

The substance is a colourless to pale yellow liquid at ambient temperature. It contains volatile constituents leading to a low flash point and the constituents are considered as insoluble to moderately soluble in water (0.014 to 268 mg/L). In water, it is less dense than water, so likely float.

The substance is classified as FLAMMABLE LIQUID, Category 3 based on Regulation (EC) 1272/2008 (CLP regulation).

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)

Summary of relevant physico-chemical properties:

Endpoint (method)

Data

Appearance

(visual)

Colourless to pale yellow organic liquid at 20 °C and 1 atm.

Freezing point(OECD 102/EU A1)

The freezing point of registered substance is stated as <-20°C

Boiling point

(OECD 103/EU A2, Siwoloboff)

The boiling temperature of the test item has been determined to be ca 199.3 ± 0.6 °C, corrected to standard pressure (101.325 kPa).

Relative density

(OECD 109/EU A3, oscillating densimeter)

The relative density D(20/20) was measured as

0.8760 ± 0,0010. 

Less dense than water.

Granulometry

not applicable (liquid)

Vapour pressure

(QSAR calculation - Kreatis)

The vapour pressure of 11 major components of the test item have been estimated by a valid QSAR. They were estimated in a range between 0.505 and 544 Pa at 25°C.

Log Kow

(QSAR calculation - Kreatis)

The partition coefficients of major constituents of the substance (more than 90% of the composition) were determined to be between 2.5 and 4.8 at 25°C

Water solubility

(QSAR calculation - Kreatis Mixture approach)

The Water solubility of major constituents of the substance (more than 90% of the composition) were determined to be between 0.014 mg test item/L and 268 mg test item/L at 25°C.

Surface tension

(OECD 115, /EU A5, plate method)

The surface tension of an aqueous solution of the test item (using a 90% saturated solution obtained with a loading rate of 1g/L) was determined to be between 53.07± 0.02 mN/m at 19.7 ± 0.5°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 considering that the structure of the known constituents of the substance are not characteristic of true surfactants, that the dissolved part of the substance is probaby not representative of the whole substance and especially that it is not the intended use of the substance (i.e. not a desired property), this conclusion should be taken with caution.
