not classified

Remarks:

Migrated information Criteria used for interpretation of results: EU

Executive summary:

The test item was administered to a group of 6 female Sprague Dawley rats at the single dose of 2000 mg/kg body weight. The experimental protoeol was established on the basis of the offieial method as defined in the O.E.C.D. guideline N° 423 dated December 17th, 2001 and the test method B.ltris ofthe Directive N° 2004/73/EC. No mortality oecurred during the study. No clinieal signs related to the administration of the test item were observed. The body weight evolution of the animals remained normal throughout the study, similar between treated and control animals. The macroscopical examination of the animals at the end of the study did not reveal treatrnent-related ehanges. In eonclusion, the LD,o of the test item is higher than 2000 mg/kg body weight by oral route in the rat. According to the criteria for classification, paekaging and labelling of dangerous substanees and preparations in aceordance with the E.E.C. Directives 67/548, 2001159 and 99/45, the test item must not be classified. No symbol and risk phrase are required.
