The studies were not performed according to OECD guideline and GLP conditions.

Key value for chemical safety assessment

Skin irritation / corrosion

Reference
Endpoint:
skin irritation: in vivo
Type of information:
migrated information: read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
key study
Study period:
May 3 to 10, 1993
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
The skin irritation 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 irritant. 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.

Additional information

Both studies, performed in the year 1993, did not follow the OECD guidelines. However the conditions applied in the study are acceptable and the results show that the substance is not irritant for skin, but it is an eye irritant.


Justification for selection of skin irritation / corrosion endpoint:
The study refers to "D-Glucopyranose, oligomers, monosulfosuccinate, coco alkyl glycosides, sodium salts", a structurally related substance to "Sulfonation products of (esterification products of C9-11 (branched and linear) alkyl-(mono-, di- and tri-)glycosides with maleic anhydride) with dipotassium sulfite". The skin irritation 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 irritant.

Justification for selection of eye irritation endpoint:
The study refers to "D-Glucopyranose, oligomers, monosulfosuccinate, coco alkyl glycosides, sodium salts", a structurally related substance to "Sulfonation products of (esterification products of C9-11 (branched and linear) alkyl-(mono-, di- and tri-)glycosides with maleic anhydride) with dipotassium sulfite". The eye irritation test, performed in the year 1993, did not follow the OECD. However the conditions applied in the study are acceptable and the result shows that the substance is an eye irritant.

Effects on eye irritation: irritating

Justification for classification or non-classification

Basing on the tests results and following the REGULATION (EC) No 1272/2008 (EU Regulation on Classification, Labelling and Packaging of substances and mixtures) the substance "Sulfonation products of (esterification products of C9-11 (branched and linear) alkyl-(mono-, di- and tri-)glycosides with maleic anhydride) with dipotassium sulfite" need to be classified as eye irritant:

 

Skin corrosion/irritation: not classified

Hazard statement: none

 

Serious eye damage/ eye irritation: Eye damage 2

Hazard statement: H319: Causes serious eye irritation.
