- TEST SYSTEM
Specification
Male and female Sprague-Dawley strain rats were supplied by Charles River (UK) Ltd., Manston, Kent, U.K. At the start of the main study the males weighed 148 - 174g, and the females 133 - 153g, and were approximately five to eight weeks old . After a minimum acclimatisation period of at least five days the animals were selected at random and given a unique number within the study by indelible ink marking on the tail and a number written on a cage card.
Husbandry
The animals were housed in groups of five by sex in solid - floor polypropylene cages with sawdust bedding. With the exception of an overnight fast immediately before dosing and for approximately two hours after dosing, free access to mains drinking water and food (Rat and Mouse Expanded Diet No. 1, Special Diet Services Limited, Witham, Essex, U.K.) was allowed throughout the study.The animal room was maintained at a temperature of 18 - 22°C and relative humidity of 50 - 73%. On one occasion the temperature and humidity were outside the limits specified in the protocol (19°C and 70%). These deviations were considered not to have affected the purpose or integrity of the study. The rate of air exchange was approximately 15 changes per hour and the lighting was controlled by a time switch to give 12 hours continuous light and 12 hours darkness.
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- unchanged (no vehicle)
- Details on oral exposure:
- For the purpose of the study the test material was used as supplied. The specific gravity was determined by Safepharm Laboratories Limited and used to calculate the appropriate dose volume for the required dose level.
All 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 its fasted bodyweight at the time of dosing. - Doses:
- 2000mg/ kg bodyweight
- No. of animals per sex per dose:
- 5
- Control animals:
- no
- Details on study design:
- The animals were observed for deaths or overt signs of toxicity 1, 2 and 4 hours after dosing and subsequently once daily for 14 days.
Individual bodyweights were recorded prior to dosing on Day 0 and on Days 7 and 14.
At the end of the study the animals were killed by cervical dislocation and subjected to gross pathological examination. This consisted of an external examination and opening of the abdominal and thoracic cavities. The appearance of any macroscopic abnormalities was recorded. No tissues were retained. - Statistics:
- no

Applicant's summary and conclusion
- Interpretation of results:
- other:
- Remarks:
- Not classified in accordance with the CLP Regulation
- Conclusions:
- The acute oral median lethal dose (LD50) of the test material in the Sprague-Dawley strain rat was found to be greater than 2000 mg/ kg bodyweight.
- Executive summary:
A study was performed to assess the acute oral toxicity of the test material in the Sprague-Dawley strain rat. The method used followed that described in the OECD Guidelines for Testing of Chemicals (1987) No. 401 "Acute Oral Toxicity " referenced as Method B1 in Commission Directive 84/449/EEC (which constitutes Annex V of Council Directive 67/548/EEC).
Following a range-finding study, a group of ten fasted animals (five males and five females) was given a single oral dose of undiluted test material at a dose level of 2000 mg/ kg bodyweight. The animals were observed for fourteen days after the day o f dosing and were then killed for gross pathological examination.
There were no deaths. Common signs of systemic toxicity noted were ataxia, hunched posture and lethargy with additional signs of decreased respiratory rate. Animals recovered one day after dosing.
All animals showed expected gain in bodyweight during the study.
No abnormalities were noted at necropsy.
The acute oral median lethal dose (LD50) of the test material in the Sprague-Dawley strain rat was found to be greater than 2000 mg/ kg bodyweight. No symbol and risk phrase are required according to EEC labelling regulations.
