Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
February 22, 2009
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: The test was carried out following OECD guideline 102 and EC directive No. 440/2008 A.1
Qualifier:
according to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Deviations:
no
Qualifier:
according to
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Deviations:
no
GLP compliance:
no
Type of method:
capillary method
Specific details on test material used for the study:
Name: BLANCOLEN® HP (Disodium hydroxy(sulfonato)acetate)
Batch No.: 080129
Decomposition:
yes
Decomp. temp.:
> 180 °C
Sublimation:
no

No melting point (or range) of the test substance BLANCOLEN HP was observed below 300°C. It was noticed that the test substance decomposed because the colour changed from white to slight grey/brown at 180°C (453 K).

Conclusions:
decomposition at temperatures > 180°C
Executive summary:

It was noticed that the test substance decomposed because the colour changed from white to slight grey/brown at 180°C (453 K).

Description of key information

No melting point was determined. Decomposition at approximately 180°C.

Key value for chemical safety assessment

Additional information

No melting of the test substance was observed below 300 °C. It was noticed that the test substance decomposed due the colour change at approximately 180 °C.
