Sulfonation products of disodium sulfite with (esterification products of C10-16 (even numbered) Alkyl Polyglycosides with maleic anhydride)

Acute Toxicity: oral

Administrative data

Endpoint:

acute toxicity: oral

Type of information:

experimental study

Adequacy of study:

key study

Study period:

May 3 to 17, 1993

Reliability:

1 (reliable without restriction)

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 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
