Sulfonation products of dipotassium sulfite with (esterification products of C9-11 (branched and linear) Alkyl Polyglycosides with maleic anhydride)

Boiling point

Administrative data

Endpoint:

boiling point

Type of information:

migrated information: read-across from supporting substance (structural analogue or surrogate)

Adequacy of study:

key study

Study period:

From July 17 to 27, 2001

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: Eucarol AGE SS (D-Glucopyranose, oligomeric, 6-(hydrogen 2-sulfobutanedioate), 1- (coco alkyl) ethers, sodium salts) was used as supporting substance due to the structural analogy. It can be expected a similar structural features.

Applicant's summary and conclusion

Conclusions:

The test material initial boiling point temperature was 98°C. As the temperature increase, it was observed an initial sample degradation, starting from around 103 °C with evolution of gray vapours and a slow polymerization. The sample degradation was completed at around 160°C with the appearence of a solid dark material inside the boiling reservoir.
