Test animals
- Species:
- rat
- Strain:
- Sprague-Dawley
- Sex:
- male/female
- Details on test animals or test system and environmental conditions:
- Animals were randomly allocated to cages. Females were nulliparous and non-pregnant. After an acclimation period of at least five days, animals were selected at random and assigned a number unique within the study. Animals were housed in groups of three by sex in solid-floor polypropylene cages with wood flakes. Except for the overnight fast immediately before dosing and for approximately three to four hours after dosing, food and tap water were available ad lib. Temperature was controlled to 19-25 °C; relative humidity was controlled to 30-70%. Rate of air exchange was at least fifteen changes per hour. Lighting was controlled to give 12 hours continuous light and 12 hours continuous darkness.
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- peanut oil
- Details on oral exposure:
- Test material was freshly prepared as required as a suspenion in arachis oil BP. Animals were dosed once only by gavage using a metal cannula attached to a graduated syringe. The volume administered to each animal was calculated according to the fasted bodyweight at the time of dosing.
- Doses:
- 2 g/kg as suspension in peanut oil; final dose volume 10 ml/kg
- No. of animals per sex per dose:
- Three
- Control animals:
- no
- Details on study design:
- Animals were observed for deaths or overt signs of toxicity 1/2, 1, 2 and 4 hours after dosing and subsequently once daily for 14 days. Individual bodyweights were recorded prior to dosing and seven and fourteen days after treatment. At the end of the observation period, animals were killed by cervical dislocation. All animals were subjected to gross pathological examination.
- Statistics:

- Mortality:
- There were no deaths.
- Clinical signs:
- other: No signs of systemic toxicity were noted during the study.
- Gross pathology:
- No abnormalities were noted at necropsy.
- Other findings:
- none
Any other information on results incl. tables
No mortalities or signs of systemic toxicity were observed during the observation period.
Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The acute oral median lethal dose (LD50) of the test material in the Sprague-Dawley CD (Crl: CD* (SD) IGS BR) strain rat was estimated as being greater than 2500 mg/kg bodyweight. No mortalities were noted in animals treated with 2000 mg/kg bodyweight.
- Executive summary:
This study was performed to assess the acute oral toxicity of erucamide following single oral administration to the Sprague-Dawley rat. The test material was administered orally as a suspension in arachis oil BP. Clinical signs and bodyweight development were monitored during the study. All animals were subjected to gross necropsy examination. There were no deaths. There were no signs of toxicity. All animals showed expected gains in bodyweight over the study period. No abnormalities were noted at necropsy. The acute oral median lethal dose (LD50) of the test material in the Sprague-Dawley rat was estimated as being greater than 2500 mg/kg. No mortalities were noted in animals treated with 2000 mg/kg bodyweight. The test material does not meet the criteria for classification according to EU labelling regulations Commission Directive 93/21/EC.
