Test animals
- Species:
- rat
- Strain:
- Sprague-Dawley
- Sex:
- female
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- unchanged (no vehicle)
- Details on oral exposure:
- The undiluted test substance was administered to the stomach using a stainless steel ball-tipped gavage needle attached to an appropriate syringe. Following administration, each animal was returned to its designated cage. Feed was replaced approximately 3-4 hours after dosing.
- Doses:
- 2000 mg/kg
- No. of animals per sex per dose:
- 5
- Control animals:
- no
- Details on study design:
- An initial limit dose of 2,000 mg/kg was administered to one healthy female rat by oral gavage. Due to the absence of mortality in this animal, four additional females received the same dose level, sequentially. Since these animals survived, no additional animals were tested. Females were selected for the test because they are frequently more sensitive to the toxicity of test compounds than males. All animals were observed for mortality, signs of gross toxicity, and behavioral changes at least once daily for 14 days after dosing. Body weights were recorded prior to administration (initial) and again on Days 7 and 14 (terminal) following dosing (see Section 9). Necropsies were performed on all animals at terminal sacrifice.

Applicant's summary and conclusion
- Interpretation of results:
- practically nontoxic
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the conditions of this study, the acute oral LD50 of triisotridecyl phosphite is greater than 2,000 milligrams per kilogram of body weight in female rats. In accordance with the provisions of Regulation (EC) Number 1272/2008 amended by Commission Regulation (EU) Number 286/2011 of 10 March 2011 (ATP002) on the Classification, Labeling, and Packaging of Substances and Mixtures, classification is not required based on the results of this study.
