Administrative data

Endpoint:
eye irritation: in vivo
Type of information:
experimental study
Adequacy of study:
key study
Study period:
May 3 - 10, 1992
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
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. Eucarol AGE SS (D-Glucopyranose, oligomeric, 6-(hydrogen 2-sulfobutanedioate), 1- (coco alkyl) ethers, sodium salts) was old name for EUCAROL AGE SS/ND before REACH regulatory - new nomenclature. The substance was identified with: CAS: 151911-53-4 EC: 500-331-5
