Administrative data

Endpoint:
vapour pressure
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:
Vapour pressure at 20°C = 34 hPa
The vapour pressure was measured for the aqueous solution and the value reflects the water content.
