Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data

Endpoint:
acute toxicity: oral
Type of information:
migrated information: read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
key study
Study period:
May 3 to 17, 1993
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
The acute oral toxicity test, performed in the year 1993, did not follow the OECD. However the conditions applied in the study are acceptable and the result shows clearly that the substance is not toxic. 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. They are both in the category of the long linear and branched chain alcohols. Key points are that the members share the same structural features, similar metabolic pathways, common mode of ecotoxicological action and common levels and mode of human health related effects. Member of the long chain alcohols are of a low order of toxicity following acute and repeated exposures. The overall toxicological profile of the sub-categories of linear and essentially linear alcohols is qualitatively and quantitatively similar for all end points.
