Applicant's summary and conclusion

Interpretation of results:

practically nontoxic

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

Exposure to 2000 mg/kg bw cholesterol of male and female rats did not result in mortality.

Executive summary:

Sprague Dawley rats (5/sex) were given 2000 mg/kg bw cholesterol by oral gavage. Animals were observed for 14 days for mortality, clinical signs, and body weights were recorded at the start and at the end of the study. All animals survived the 14 day observation period. All animals gained weight, and no clinical signs or gross changes were observed. Based on the absence of mortality at the tested dose of 2000 mg/kg bw, cholesterol does not have to be classified and has no obligatory labelling requirement for acute oral toxicity according to the:

- Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations (2011)

- Regulation (EC) No 1272/2008 on clasification , labelling and packaging of substances and mixtures.
