Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2011
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
Guideline compliant well documented study
Qualifier:
according to guideline
Guideline:
OECD Guideline 103 (Boiling point/boiling range)
Deviations:
no
GLP compliance:
no
Type of method:

Key result
Boiling pt.:
>= 296 °C
Atm. press.:
1 021 mBar
Decomposition:
yes
Decomp. temp.:
>= 296 °C
Remarks on result:
other: From 296°C the test item shows a boiling and/or thermal decomposition with evaporation of the decomposition products.

The test item shows a boiling and/or thermal decomposition at ca. 296 °C (at 1021 mbar) (a decomposition is most likely due to a strong residue in the crucible at ca. 600 °C (see TGA measurements)) according to the definition in the OECD guideline 103 (mean value from repeat determination; 1st

heating run).

·        296 °C (from first measurement)

·        296 °C (from second measurement)

From 296 °C the test item shows a boiling and/or thermal decomposition with evaporation of the decomposition components. The DSC measurements were confirmed by means of TGA measurements (up to 296 °C the sample shows a weight loss of ca. 5-7 weight%) under the same measuring conditions.

Conclusions:
boiling/decomposition at 296°C
Executive summary:

In the Klimisch 1 non-GLP study from Kintrup (2012) the boiling point of Sulfosuccinic (FA C12-18)E, 2Na was determined with the DSC method according to OECD 103 and EU method A.2. The test item shows a boiling and /or decomposition at ca. 290 °C (at 1022 mBar) (a decomposition is most likely due to the strong residue in the crucible at ca. 600 °C) according to the definition in the OECD Guideline 103 (mean value from repeat determinations; 1st heating run).From 296 °C the test item shows a boiling and/or thermal decomposition with evaporation of the decomposition products.

For the risk assessment a boiling point of 296°C will be used.

This information is considered to be relevant and reliable for the further risk assessment.
