Details on test animals or test system and environmental conditions:

OFA Sprague-Dawley rats (SPF caw) originated from IFFA CREDO (69210 L'Arbresle-France), were kept during a 5-day acclimatisation period. At the beginning of the study, the animals weight was contained between 176 g and 210g (males) and between 159g and 182g (females).

Applicant's summary and conclusion

Interpretation of results:

not classified

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

The LD 50 of the product LCA 01006 is higher than 2000 mg/kg body weight by oral route in the rat.
According to the criteria for classification, packaging and labelling of dangerous substances in accordance with EEC directives 67/548 and 93/21, the product LCA 01006 must not be classified "R28: very toxic if swallowed", "R25: toxic if swallowed" or " R22: harmful if swallowed".

Executive summary:

The product LCA 01006 was administrated to a group of 10 Sprague-Dawley rats (5 males and 5 females) at the single dose of 2000 mg/kg body weight according to the experimental protocol established on the basis of the official method as defined in the OECD guideline n°401 dated February 24th, 1987 and the test method B.1 of the Directive n°92/69/EEC dated December 29th, 1992.

No mortality occured during the study.

No clinical signs related ti the administration of the test ptoduct were observed. The body weight evolution of the animals remained normal throughout the study, similar between treated and control animals.

The macrsocopical examintaion of the animals at the end of the study did not reveal treatment related changes.

In conclusion, the LD50 of the product LCA 01006 is higher than 2000 mg/kg body weight by oral route in the rat.

According to the criteria for classification, packaging and labelling of dangerous substances in accordance with EEC directives 67/548 and 93/21, the product LCA 01006 must not be classified.
